It's a 2012 dodge.
Some cars have a separate charge circuit, further away from the alternator
Anything built in the last 40 years should never have the battery disconnected while running
Lots of anecdotal evidence says its fine but I've seen it plenty of times across everything from the 80s onward. Pull positive = huge increase in alternator voltage.
You might not kill anything, but you also might kill stuff.
That would just be an external voltage regulator. Still all part of the same circuit.
All my bikes for example have had that.
Then I'm horribly misinformed about this point. If the output from the alternator does not marginably change from 14V-12V I do not see how it could damage electronics. Electronics generally are limited by their resistance. I do not how it interacts with potential "forced current" from an alternator
Disconnecting the battery is an old school boomer trick that shouldn't be done anymore. A lot of people think it's a good way to go.
Voltage spikes in the literal alternator should be managed by any circuitry behind
And you're right. Electronics are limited by resistance. What happens with the voltage goes up and resistance stays the same?
The battery is part of the voltage limiting. Means it's on the dc side of the regulator, not the AC side with the alt.
The only way to "force" current is to increase voltage.
The alternator voltage itself isn't what increases, necessarily.
That goes up and down with rpm
Voltage should not go up because the alternator circuit buffers it in coils and caps
Incorrect.
Voltage regulators in cars are not that sophisticated. They rely on the battery for that buffer.
A regular alternator circuit has a stepdown-converter that dynamically manages voltage "spikes"
I can't imagine that. It would wear out the cells horribly quickly
Nope
So you're saying the battery acts as a RCF circuit aswell?
If you hook up a battery at 10v to a battery at 13v the measured voltage of the 13v one will drop to the average of the two.
This is why, when connecting jumper cables to a dead battery the supply vehicle will read a much lower voltage
Even though there isn't anything wrong with it, the battery "draws down" the circuit.
This is a fundamental aspect of how vehicles maintain a steady voltage.
The alternator and regulator, when under load, will be designed to operate at a still higher voltage to pull it down to the necessary charge voltage of the battery.
It's not a benchtop power supply that's cost a couple grand of hardware in it. It's a device made by the lowest bidder.
The voltage (without a load) will not drop. It will stay at 13V and with a load the higher voltage battery will discharge proportionally to the voltage difference.
This is a voltage droop. (current overload) scenario caused by the interal resistance of the empty battery
It's either charging whatever was consumed during starting, or it's running the vehicle. There is always a load.
And what do you think any other slightly discharged battery or load does?
It's a load. Which causes a voltage drop.
Last one is a good point - my explainations mostly stem from ideal power sources
You can argue all day but I've shown people a dozen times in my life with a meter in hand.
Disconnect battery positive, voltage shoots up.
Depending on C value of the battery (thereby probably its size) this it not neccesarily the case
The simple fact is the regulator relies on the battery being present in the circuit.
Point taken, will remember!
You can Google this and get clear explanations from those smarter than I
It's more of a reference point than anything else. But I'm sure there is a technical reason
You also run the risk of the higher voltage at the regulator cooking the regulator itself. Thereby ensuring replacement of the alternator even if it was previously good. Kind of ironic tbh.
10v = one shorted cell, IIRC.
variable voltage or duty cycle field excitation windings, IIRC.
Yes. But why it occurred is the thing that I don't know or care about lol
Something of a guess but not quite:
Full discharge actually can cause mechanical damage in the form of flakes falling off the plates.
Once those flakes build up to make contact with the plates, short circuit.
And I don't need the technical explanation about dendrite formation haha
And there it is
The root cause being whatever shit the bed on the vehicle to result in killing the battery. I know how a battery dies.
well, now someone else gets to learn
But the mystery is how it went from "drove home under its own power and parked" to "1 volt at the battery" in a few hours.
The obvious is "alternator is shot"
My wife's van had the alternator fail while driving: stator coils ended up shorted to alternator case. Full battery current going through the coils to ground. Coils were smoking. Vehicle died while driving, not even enough power to let some piddly solenoid allow the shifter into park.
Did... did you murder it to play the hero to the miss?
Yeah. That's pretty catastrophic. This thing started fine, drove 6 miles across town then parked and suddenly the battery was junk.
(I don't know if it was a direct short, or the rectfier pack failing short, or what)
3spoopy5me boys
600? Are the new ones fucking gold plated?
They just might be
Alt is like 350 and tax. Battery $200 and tax. Everything is bullshit now.
not the case if the diodes fail it will eat the battery and let the car run same goes for the Voltage reulator if the car does not turn off the alternator which some can do it will run the car and eat the battery seen it tones of times car will run but will not start without help
yep they are both a form of capaciter and sacrificial media which is why alternators often eat batteries
seen similar at Auto zone the regulator fails low (providing a low voltage) and the car limps home but that is all it had charge to do that or diode failer as that kills batteries in less than a week (only time frame I know from doing the warranty work)
Ohh damn
And we now have 14.57v at idle.
A bit high but with in standard specks
Eh. 14.8 is the upper spec.
Realistically 14.7 is the ideal upper limit, but there's always a small voltage drop between the alt and battery anyways.
Either way this 340 dollar damn alternator better last.
sounds high from what I remember abought right for the Gold 100% new alternators but the remans were about onpar with the batteries at ~200
a non insignifigant amount of my job was testing alternators
Remember, damn near everything doubled in cost in the last 3 years.
i saw that real time but my data is less than a year old did not expect it to go up that fast
Especially the stupid "smart alternators"
Curses to the engineer that figured that one out. I understand the point of it but it only really serves to perform better on the epa tests and doesn't do a lot for the consumer.
Other than cost us 3 times as much to deal with the charging system issues that is.
Dc to dc chargers with sensing features to shut off when the car drops the alt output out are expensive and necessary.
the only smart alternator I saw was a toyota that was normal price but when it failed the car turned it off I do know the doge one like you have is weird and can't be bench tested at AutoZone as the regulator circuit is on part of the alternator
that and the hub has a weird clutch system in it
I also know that some dodges have an issue with oil getting into and burning up the windings (saw one come in to my store and looked it up)
My 2010 dodge controls the alternator voltage via the ECM as far as I know.
yep on most cars the regulator is part of the the alternator
Yep. Ecu controlled to drop load to save fuel in the specific conditions that benefit only during the damn mileage test.
And piss me, personally, off.
Miata gang.
Tuk tuk gang
Shitbox gang š š
Shitbox gang
I gotta get up, put pants on, and bring this fuckin diff to a real adult that can deal with it.
You had the whole week and didnt
Cuz I got the tools I need to set backlash and preload and shit but zero experience doing it so fuck that
I did not have the whole week. I worked all week and put an alt and battery in that dodge
Hehe
Due to limited time after work it was 3 days just to diagnose, take apart, and put together
No work today?
Nah I went to disturbed concert last night so I took off today to fuck with this diff and sleep in
But I still woke up at 6 am anyways
Xd
4 hours of sleep gang
I went to store and got a bag of chips, should of had more, fridays be bad muncheis as only a 9am snack/lunch vs non at 12 and then it just means dinner only
I don't have my glasses on and I thought that said you got a 9mm
I was like... you're not allowed wtf
Well yes, but lots of work
Not allowed yet*
EV & HEV gang
Bigger shit box gang u mean?
Why a shitbox?
Dunno
@remote plume i see u play warthunder
Heh, yea?
Wanna play some later
Already plans for today, I'll probably play some tomorrow, same time around.
Ill be driving a racing sim then, work fun trip
Ooo sounds fun
Actually, kinda looking for someone to play asetto corsa comp. With... like a group of people that don't dirty race
F1 too
But it seems no contact wil be done for the more serious ones
Wich is a shame as i am but also competitive, but i know for sure some guys gonna wreck no matter what, heck one coworker hit a solid half wall today wich he knew was there as he didnt look
I think some game has that system of no contact at movement vector differences of greater than some speed i.E. only slight touching allowed, no warp speed ramming and cannonballing
Idk, but with slight touching i can still push people away xd
Broken boi
ayo clean asf
That part isn't lolol
Well the others are
Idk yet. Trans shop has it, they'll get to it when they get to it
I estimate this will cost me between $100 and $1000 kek
It's a rather sensitive matter and the cost if you fuck it up is high
Treu
It's just a few thousandths of an inch between "lasts 200 thousand miles" and "grenades in 200 feet"
sorry, sold mineā¦.
Well yes but you're far less likely to just grief poeple :D
***Ya got oil on your phone? š¤ ***
Found a guy who can weld it. He needs cad work done. I have a 3d scanner. Shit about to be bartered.
Oh shit I've been here for s while but didnt know there was a car place
I've got a Honda that sat for several years that I've cleaned up and got running. The srs module shit the bed at some point so I have to fix that, but I fixed a seam leak and cleared out an any infestation.
Welcome to the gang
I feel attacked
Anyone had any dealings with MyAirbag?
They make an srs module for the Honda and it supposedly has a 1 year guarantee. I'd rather get that than something from a rando on ebay
Lol @ last minute race car shit. Thing didn't even run yesterday
I've been doing little piddly shit for this guys cars for like 7 years and I haven't been to a single one of the races
Life is dumb
Also on the note of my gas gauge being broken as fuck, does anyone know how to reprogram an odometer or know where to check? I need to get a new gauge cluster at some point and I'd like the milage to match
I can figure out the legal stuff because I'm pretty sure it varies state to state, but idek where to begin to get the milage matching
Depents entirely on your car. It seems, yours is modern enough to have the ECU be the odometer and just transmit those numbers via CAN to the gauge cluster, along with speed and RPM and such
So if you just replace the gauge cluster you probably won't have to do anything
The milage is stored on the gauge cluster
So you get shit like this
I believe even the 2015-2022 tenth generation civics store milage in the cluster. It probably has ECU milage as well, but I'm not sure if the ECU milage corrects the dash milage on the newer cars. On the older cars it sadly does not
GM vehicles are also bad about storing the milage in the cluster but that's a different story
Yeah a lot of times when you need to buy a cluster new you need it programmed.
Luckily older Hondas are super simple so it's just plug and play except for the milage. So I'll probably have to have a shop reprogram the new odometer and slap a sticker in the doorjamb

300 hp N/A NA with the lfx v6
you mean 5 right?
Wat
okay so around 300hp/ton⦠iām used to 400 (high torque) to 650 (low torque) per ton so in a typical 6+ gea ābox that makes 2nd gear about 5th
they "accidentally" installed the 2" spacers š
about 25 to 30m above sea levelā¦. but if that car has 300hp my am will be producing that pwr at around 4000 rpm (8500 rpm limiter) and the Ultima around 6000 (10500 rpm limiter)
Oh. Didn't know it was a contest against a totally stock engine lol
my point is that cars 2nd gear will feel like 5th gearā¦
also that car canāt be considered stockā¦.
That doesn't make any sense though. 5th gear accelerates slower than 2nd. So more power makes 2nd accelerate like 1st used to.
And now 1st is just for destroying tires
Motor is though
thatās cause they put a underpowered engine in it š¤£
Boi
so they canāt driveā¦.
Merica
point of interest both the Ultima and the AM are lower capacity than the LFX!
Lfx will daily grocery getter with 500 rwhp though with a supercharger.
There's something to be said about those things
My primary interest is that there's a mostly bolt in kit to put one in, and it'll increase the mileage of the damn car by a lot
With a 10 gallon tank and very little room for more fuel that's valuable lol
I dailyed a 645whp Ultima for3 years w/out issues š
see nice ān cheapā¦
poor and happy vs rich and bored/unhappyā¦
Ask me when I'm 60 and still need to work for a living
The car being faster isn't going to add as much value as simply being functional will I'll tell you hwat
soo keep it stock!
It'll probably explode
then you are doing something wrong š¤£
It's got 200k miles on the clock and I'll be pulling a trailer.
I'd say that's wrong enough
maybe you need to get a Scania instead⦠they last for 500ā000k miles+ and have a much bigger towing capacity!
Just drive my silverado then
Nah. 5.3l v8
see the Scania is better š¤£
Probably
I donāt think it matters much!
Kinda does though. Especially if you've got a 1st gear that's like 10:1
Or more
First is 4.5 ish and final drive is like 3.7 ish. That's stupid.
16.7 ish kek
43k
Or thereabouts
tbh, from the HGV taster session I did, typically youāll be pulling away is normal done in 4th-7th
lower gears are for crawling up hills
Yeah but 1st is still there for when you need to tow the earth out of orbit
I'm pretty sure at that point the truck just sits still and moves the continent.
you just keep on dropping gear until you stall out or stop slowing down
iām half considering getting my class 1 hgv license!
Do it
Idk what that is but yes, do it
big rig driving license
Ah, thatās a cdl in the us
That's where i'm going at this point. Bought a modified but not tuned 2.5T subaru with 186k mi, it really needs a new shortblock and turbo for the sake of reliability, but i also just wanna tune it and send it until it blows up, downside to that is it'd cost alot more to replace heads and other things that break when engine grenades itself.
Class M, E, D, C, B, A + various endorsements.
Merica
Plus some states have a DJ or MJ for junior drivers
And learners permits
That thing is sick
Sit back and watch Ryan Eversley make good use of the push-to-pass function to churn out a 1:41 during the tail end of the 2019 25hrs of Thunderhill. This ended up being the fastest lap overall.
Aw it's a cute little baby v8
With massive balls
Lmao
Thunderhill sounds like a Ridge Racer 4 track
The actual track name in RR4 is Wonderhill
It's a blast to load up on my phone
I use retroarch, but there's probably a better standalone emulator for PS1 on android now
Might be able to get it working on PSP emulator too, but don't quote me on that
Gran Turismo 2 plays well too
but typically if i'm gonna play gran turismo i'd rather sit down and play GT4 on my ps2.
68mm stroke and 10k5 rpm red lineā¦. damn thatās a low torque arrangement!
I googled it and immediately saw it was a Hartley. It all makes sense now haha
Hartley has some sick engines
Soo my Smart Roadster coupe Brabus produces 109hp and 107lbft at the wheels š
New car bought?
and kerbs at 871kg (which is 50kg over official kerb)
I bought the Brabus a while ago
I didnāt need a 5th wheel for the AM š¤£š¤£
had someone skim the head down so itās got 9.3:1 cr, changed the compressor wheel over and upped the boost
Those brabus smarts be crazy fr fr
Is it still a semi-automatic? Some weeks ago I kinda got smoked by one at a traffic light
theyāre okay, 0-100km/h in just under 10s means they are fast enough to be safe making the āforwardā decision but not more than that
The box is either a SCT or DCT itās not a normal auto
seriously though iām looking at a 152v EV conversion
direct drive
Just under 10s means actually faster than my car xF
which is crazy cuz they have like a 1L I3, where I have 2L I4
Saw someone making a pickup truck out of essentially two smarts, looked rad!
0.7L I3 turbo
Exactly
iām guessing 2L n/a
Babus Smart stuff is so goofy I love it
Just Audi things
It's just luxury stuff, like side assist, and my airbags
You know, the non important stuff
adding them?
so mustāve charge you dollars to the base-8?! š±
We out here computing and shit
That price is pretty good though. Some places charge 200 bucks or more for each one. The bastards.
Wait, you guys have emissions tests?
Not in my state but the scanner still just says "hey everything is working correctly" or "some systems might not be working correctly"
Or red "shits fucked mate she's not road worthy"
But in the US it depends on the state
And sometimes county. In wi it's county specific. Up north there is no emissions check (just an obd2 scan) but there is here and obd1 cars are exempt
Same in UT, my county is the exception to the rule where most counties have emissions.
where i live is no emissions no inspection
nice for me not having to deal with that, sucks that that means more people on the road with unsafe cars.
No just Audis being Audis and having electrical issues. Although one of the issues is a vacuum leak
Thats some electrics, alright š¤
Damn talk about anti-slip
Talk bout the skid marks on ya plates
more inventive than the usual tyres stacked on top of each other and a bit of wood for a table topā¦
Talk about your table going bad eventually
"man this tire just doesn't grip plates like it used to"
The jokes are just a boring re-tread.
more like a tire-some table, eh?
X_X i need to get an awd vehicle
In Wisconsin it's practically required
And I imagine any other state with a heavy snow
Yep
Good winter tires is better than AWD
AWD is beneficial if youāre breaking through fresh snow. If youāre driving on plowed roads then good winter tires is all thatās needed
Or AWD is great for off roading
But AWD on summer tires is never gonna beat FWD/RWD on winter tires.
It depends
AWD doesn't help stopping, only powered traction
it can help with turning a bit
It can help with maintaining control, yeah. Certainly doesnāt do anything for stopping. But if you canāt get moving either then stopping isnāt going to be your concern
So, ya know, it depends
though anything is better than an unloaded rwd ute/pickup
I have that they sell 70# sand bags just for that
I prefer good all-seasons on my car, living where I live now has told me not to trust the weather
add drive shaft lash on a tuck that does not have ABS and winter was fun
Drifting is fun
except when trying to stop
I never felt the lack of ABS hindered my experience with stopping
it does when it is icy and you are in an old unloaded pickup
Fair enough, I never drove a pick up sadly enough 
more it only matters when it is slick as it can pulse the pedal faster than you can
The catch is when youāre fighting the pulse and lock the brakes up anyway
I see that happen more often than not in the winter, especially with small cars and beginner drivers.
And people have no idea how to steer when their brakes lock-up.
This is broke cope. Both is better.
Sadly my Mirai is FWD only
Get a second one and weld the fronts together
My idea was to get an Escalade and 2nd Mirai, then put both Mirai engines and tanks in the Escalade, then I have the most fuel efficient Escalade
What dual engine 4wd diy Frankenstein?
Yes
Have you ever seen the nose of a Mirai vs the Escalade?
It's more than twice the size
That would just result in an underpowered escalade.
The fuel efficiency is mostly set by the aerodynamics and weight as most modern engines are roughly the same thermal efficiency
So far all Escalades I seen have around 300hp, 2 Mirai engines will be around the same.
To be honest all I want is a quiet comfortable SUV that looks like the Escalade 
So you mean an escalade. They're already quiet. Do you just have a bunch of busted ones running around with rotted out exhaust?
Having a v8 doesn't mean it's loud
I hear and feel even quiet combustion engines, for me they're still loud.
Everyone does lmao
Personally I find RWD with appropriate tyres best.
I know so many people who don't.
They usually tell me a Rolls-Royce is quiet, yet here I am, getting annoyed by the engine noise
My hearing is sensitive enough that I always have to wear earplugs so I don't go deaf outside.
...ok
I really prefer the sound of an EV, or the absent of sound.
No donāt even know te it is
The main disadvantage, an Escalade drives 1:8 Litre, my Mirai drives 1:100 KG
So driving 1:50(?) KG doesn't sound bad to me either.
Keep in mind, in my area a litre of fuel is ±2.- for petrol, and ±10.- for a kg of hydrogen
She means a hydrogen escalade
imo two mirai āenginesā isnāt equivalent to a single Escalade v8 because theyāre different systems
Plus one of them would still move that tank just fine anyways.
A plug in hybrid that utilizes solely electric power for drive and only uses ICE for power generation would be the best option. You can get away with way less engine to do more or less the same work as the battery can take the surge power needed for acceleration and recover energy during cruise and idle functions.
That's why the Brat/Baja existed, and subsequently didn't exist.
The problem is high gas prices, hydrogen is much cheaper to fill up than a gas car.
Plus it's way way more efficient
If you can find a gas station offering hydrogen anywhere
I've never seen one
There are very few in the US. Theyāre more frequent in Europe but still not as common as petrol stations
There 1 on 1km distance from my house, and a ton other in the Benelux with more planned than we already have.
Then yeah sure
Not to mention if really needed I can ask nearby bus stations for fuel
If only the US took on interesting fuel types. Diesel cars never really sold here, and it took tesla building a shitton of EVs and stations for everyone to warm up to that idea
The main issue I see with fuel cell over gas electric hybrids is roadside support or remote use. Itās a lot easier to use a gravity feed can of fuel than transfer between two pressurized tanks
Hydrogen can be cheaper. It isn't in the US lol
Well, it's ±10.- per kg here, and my Mirai only has 4KG tank.
Do you know your cost per km?
It costs me at least 140.- to fill an Escalade, only 40.- to fill an Mirai.
Lets say I drive same distance with both then the Mirai still is way cheaper.
Yeah, here you're probably more likely to find a gas station selling 100 octane race gas than you are to find one with hydrogen
I know where there are several gas stations that sell race fuel. I don't know of a single hydrogen fillup point.
Like, van is 6 months old or owned for 6 months?
For me it's the opposite, I don't know any locations that sellrace fuel, but do sell hydrogen
The owner is 6 months old.
Finally caught up, yea a FWD with snow tires isnt gonna have fun with a yearly average of almost 4 meters of snow (149 inches) a year where i'm going
So that averages to a monthly snowfall of 12.41 inches (Though it doesn't snow year round so that number is drastically larger for the months it will snow)..... my old beatup corolla isnt gonna be able to handle that
Are the roads plowed and maintained where youāre going?
Where we're going, we don't need roads.
If they are then snow tires should set you up. If not and your car is going to be doing its own plowing the awd or 4wd might be worthwhile
I've had my car stuck on snow in the middle of the road before simply because the plows don't do the side roads sometimes for days after the storm.
Literally 3/4 wheels off the ground at that point because it just piled up underneath. Use to have a photo of it dug out with the wheels all a couple inches off the pavement.
Yeah, a vehicle that is higher off the road can make difference
from people who i know who live in the area the roads aren't well maintained
6months old
Atleast 6 months is at company but we got it basically new after dealer put decals and that type of stuff on
I mean the seat of the couch broke and they fixed it the shop and werk later it broke again
They accused my foreman of breaking it with a pry bar
Wouldnāt believe it somehow actually broke
But his van was in shop last month I think for oil change and whatnot probably, but the shop probz didnāt add any oil or such
Not first time a car came back with missing fluids
Sounds like you need this Ripsaw EV3-F4
I wish I could have 1 of those, but they're very illegal where I live
Tf they gonna do, get stuck in the dirt?
Also rubber tracks are the way to go
Probz can get em legal itās just lots of hoops and money but if u can afford that so can license
yea im good i dont need a wannabe tank
When are we getting this in star citizen?
Rip kit upgrade for the Ursa/Lynx plz
Funny enough the army has them as scout tanks because they're very very fast.
Plus tehey come armored too and a 50call on top remote controlled
There used ot be a show on discovery, back in the days, heck must be 13ish years ago, that actually was about the company making those
Which army?
They wouldn't be considered a tank in any army in the world. Last I checked they thought they might be able to get them developed for that task but zero armies have adopted them for that.
I think thereās a remote controlled version that the US army is evaluating
Neat
Not a tank, but they are light armoured vehicles, but thats i believe mostly for smal lcalibere and not bombs or such
Barely armored.
True but more than your average car, and if you fast as frick its a good combo
All the downsides of an amored vehicle, none of the upsides.
Speed is largely irrelevant on a ground based vehicle in 2023 when a predator can drop a guided smart bomb from 20k feet.
Or a relatively cheap missile doing Mach 2.2 gets shoved up your arse.
At that point you might as well be on a motorcycle.
Or a 200dollar drone and a grenate and a release mechanism
Speed helps prevent being acquired quickly. Nothing really helps once youāve been acquired.
Owh but there is
now introducing the tactical pocket nuke, obliterate anything in a 1mile radius to prevent being captured. Side effects are death, nuclear poision
not for inserting
Someone has been watching Ukraine dunk on Russian armor.
why do you want a car that sounds like a drill?
what
that is not a fair comparison a small sedan VS an over sized SUV not only is the fuel economy going to be vastly different but so will the tank size

Lexus Is Going To Change Steering Forever With Their New Yoke!

The Lexus RZ 450e has a surprising amount in common with the Tesla Model S. They're both electric, they're both al...
Here is the explanation why Lexus steer-by-wire systems
And the F1 cars use a standard hydraulic power steering pump I just confirmed. So just like regular old cars.
Yokes are still butt
I was wrong with the F1 cars
Lack of mechanical feedback with the road is shit for racing.
But still it's a nice system, I personally never liked the multiple turns of a normal steering wheel
And I hate variable turn rates.
But then I play games like FH5 and vehicle games with a HOTAS 
I want my steering wheel to directly correlate with wheel angle.
So I know exactly where it is, rather than some variable figure that's up to the computer and varies with speed.
Anyone who jerks the wheel 90 degrees at 80 mph in a panic is small brain anyways.
I just care as long my vehicle is stable.
That's never been an issue for any properly designed car ever. The steering wheel has nothing to do with stability at speed
My c6 and my miata are both rock solid at 100 mph
I am a real ADHD brain with very sensitive hearing and sight, so the less inputs I have to my brain the nicer.
But so is my 6000 lb truck
My Mirai is solid, but I don't like the multiple turning at low speeds.
I have a real skill issue with that
Owh yeah, i wonder how it goes if i where to drive to places i go with the tuk tuk, as that thing ahs a tiny turning circle but also fits anywhere
If I had the money to build a vehicle, it would have the turning circle of a tiny car, but the size of a bus
Then again i should jump start it and take it for a drive
Might do so tomorrow
Maybe drive to beach depending what time i get awake and go for a fish
But like. That's impossible.
Isnt there those light armored tanks that have 4axles all steering? They aint small but they can turn fast for their size
Just add lots of turning axles?
4 axle steering.
Front and back steering axles, look at the Hummer EV, which has a tiny turning circle
We had busses where I live with 2 axle steering that had a turning circle than a car
Throttle by wire is bad enough.
Only a fool would trust steering or braking by wire.
4 wheel steering derp someone else already said it
I mean, aint they still using cables lots in airplanes? Or a combined thing where hydraulicactivates wire and such for thing
Still limited to a diameter equal to the length of the bus
My miata can turn around in less than said bus
š
My tuk tuk can turn around in less than said miata and bus
Idk about less than the miata length
Technically if i just step out and pick up the front it can be turned in a 30cm radius of the outer wheels
I mean, I trust it more than majority of assholes on the road that got their licence with a pack of cereal.
Owh yeah
When i go to office, theres two diff highways merging where both are one lane, one goes on highway u exit other is off ramp
Truck comes i slow down to go behind that but i have a trailer, van behind that truck had a bigger gap from truck than me and sped up
Other driver's skill or lack thereof is irrelevant. I don't trust a system like that not to fail. And when it does fail, it's impossible to fail safely.
Power steering on a more traditional steering system fails? You can still steer but with greater effort.
Power assist fails on braking? You can still brake.
But as i dont wanna break too much as trailer and gaining speed again wich does need to go as im going up a incline that van isnt, he got mad and honked at me as i didnt let him in while i had to wait for him to let me in
He tought as his van was bigger id be scared
Mice chew through a tiny little wire and you lose your brakes? Screw that.
It has many redundant systems, unlike majority of cars.
And what if your driving column rusts?
Then it breaks and you have less control than a steer-by-wire system
Aka do your damn maintenance on time and ur fine
Mechanical failures like that tend to be gradual, and show significant symptoms before outright failure.
Electrical failures tend to be sudden and without any warning.
Nevermind the possibility of software failures in whatever brain box is responsible for controlling the steering in such a system.
I like my car and tuk tuk, nothing much electronic wise not that im mechanically good, but yeah
Or some other module on the same CAN bus doing something stupid and interrupting the communication between steering controls and actuator
Then drive a VW Beetle.
Don't drive any modern vehicle.
Only thing is the car has soemthign draining its batt super slowly wich i think is a tiny ass short in the interior light but oh well, jump start and it goes
Computerization and electrification is GREAT for some things.
But the industry has shown it can't be trusted for safety critical things to be completely computerized.
See Toyota unintended acceleration.
All im saying is, i like my knobs in my van and my car
Can just yeet on ac or whatever by smashing the dash
Aint there really anymore in new cars what i heard
Least they know in work vans and shit that stuff is important
Or they know the buyers will go elsewhere if it dont got it?
Keep in mind, a throttle cable is more dangerous than throttle by wire.
If your wire breaks the throttle doesn't work, if a throttle cable breaks, good luck stopping the engine.
Completely wrong
If a throttle cable breaks, the springs on the throttle close it.
FAIL SAFE.
Not on the engines I have seen.
Well if its a manual its easy
Just slow er down by shifting down, then just pop the clutch and let it stall
On the engines I have seen the throttle is only closed when the wire pulls it back or closes it, if there's no wire attached it's all the way open.
I don't think I've ever seen a cable actuated throttle in a car without a return spring on it, but I'll admit I'm not a mechanic.
You can't push a cable, so that would only work with cars that use two cables, which is not common.
Old cars had it, as soon the throttle cable broke the throttle on the engine is completely opened, thats how cars basically couldn't be stopped as soon it broke while driving.
Then they were not designed to fail safe. Which is dumb.
At least an electronic throttle can be mostly designed to fail safe, ignoring software issues. (loss of signal / power: close throttle via spring)
That's how an old fashioned throttle worked sadly, throttle by wire completely eliminated this problem
How scary a computer is, idiots on the roads are way way worse
Giving computers the ability to make advanced rapid decisions is GREAT.
Removing mechanical fallback is dumb.
I feel computers be good for like emergency braking, and perhaps a lane assist that new cars seem to have if u swerve too much
Besides that u dont need much computer work in
That's why you have a double redundant systems, Lexus has if the main battery fails, another system for the steering, if that fails there's another.
I mean, im soon going back on the toyota, i drive a ford transit, its a year newer the toyota, the only thing i love on it is the cruise as i do drive long distance lots. Oftimes and the ford caddys dont got that unfortunatly, but i hate the automatic windshield wipers, i hate for instance too, if im pulling a trailer, i have no reverse cam
The ford, bro i can almost jack knfie that shit as i have a camera in the rear that will still be on with the trailer, the toyota not so much
Not that i need but in tight pinches thats something nice
Plus sometimes i barely see it in mirror so its nice to know if that fucker is still going straight when reversing
Yeah, I watched the video as well.
I have my doubts on just how redundant those separate motors in the same housing truly are, and what are the single points of failure. I'm betting there are many.
Isnt that why electric still got a car battery? To power the simple things that cant be run of the big battery directly
Instead of a thing idk how to call that gets it to lower voltages or such
Same can be said for mechanical systems.
Everything is as good as the company and the owner of the vehicle.
My car soon has to go for its yearly checkup, i might of driven it one tank of gas since , so i wonder what theyll say thats gotta be fixed
As literally last 2years lots of shit be replaced already
Depends per vehicle, a good EV has at least 2 batteries, 1 redundant battery to keep the steering active and stuff, and 1 main battery.
Actually even modern ICE cars use the battery for redundancy if the engine and everything dies while driving.
Mechanical problems can be visibly seen. Any engineer or even many educated laymen outside of the company could look at a steering column and its components and see that, for example, the U Joint is worn and possibly going to fail.
Effectively nobody has the ability to audit the steering controller code to see how it responds to all possible inputs. You have to have an incredibly high degree of trust in the manufacturer and their suppliers, and in my opinion that degree of trust is not warranted.
I can tell you, many people cannot steer the wheels of a 1.5 ton vehicle when assist systems don't work.
So steering assist needs to be active when the engine dies.
Tell that to modern cars, where seeing all the mechanical components means removing the covers of almost everything
I saw today by coincoidence on insta, a vid of a battery plug, like the stuff u do in car but with a battery in that was used to make the car think it was charging or whatever or had power so it could be kept in park if it where to be in a accident, thats a flaw of electric cars isnt it
They crash and u cant just put em in park or such as they just go dead
Some are active in that situation, some aren't.
Even if you can't see them, you can often hear them and feel them.
Also speaking of bad drivers, almost hit a car at a traffic light as it didnt instantly go when light turned green, it had its hazards on but was slowly moving so didnt eevne see that first go
But it had a flat
Mechanical failures tend to be gradual. Electrical / computer failures tend to be sudden.
It was in the right lane of 2 to go straight and had a turning lane to the right and left, he went and crossed from the right straight lane trough a red i think to go leftwhile he had a flat to park, vs going right wich was closer and just pulling over
So you can on EVs, but people are so used to loud noises that they don't hear anything subtle.
Speaking off, our work is soon getting its first full ev van
Heard its already at the shop, but its gotta be wrapped, plus a water thank thrown in as electric so no roof rack or such is going to be installed
Tell me about it, cooling pumps dying, tension belt flying through the hood, exhausts falling from under the car, and people don't even notice it.
I was goonna get that i heard most liekly, but a other guy quit so im going back on that van how it seems so yea
But if it aint gonna be my new van, well im still gonna take it out for a spin 
Don't notice, or don't care / can't afford.
Before you ever drive an EV, don't judge it, don't judge a book by its cover, won't get you anywhere
I wasn't talking about EVs at any point here.
FWIW, I haven't driven them personally. I don't think I'd like the "automatic regen / 1 pedal driving", but other than that the concept is totally viable for most consumer driving needs, and I'm sure one would work quite well for most of my needs.
If you don't trust a computer, then you better can live in the jungle without technology.
You have everything you need, if you know how to survive.
Ive droven a hybrid tough, i liked that, maybe cuz it was automatic(duh) and i could just floor it but also it was quiet, if i do get to drive it for a bit, i wanna use it to sneak up on a coworker and just get as close as possible and honk, as u dont really hear it coming
My colleague once wanted to drive Mirai, he didn't know it was turned onš
Its electric? Also yeah i had the same
As if u go in the dash gets on, but turning it on its electric
I trust computers and electronics JUST FINE for some things. But some things, I don't, and I believe with good reason.
Also as it was first time automatic and whatnot, did drive nice
Was the toyota whatever it called stationwagon
Hydrogen Electric Vehicle.
With a full battery it's as quiet as an EV.
My manager when i had the van ill be getting back, he needed it as it has a water tank in, so i did take the van home then every night, i just took his car home till he returend it, was a nice ride
Hydrogen electric? Never heard of that but i assume its just similar to a hybrid with fuel just diff fuel source
With how some people steer, I wish cars had a steer by wire system that tells those people "Not today buddy"
It's basically a plug-in hybrid, but instead of an ICE, you have an hydrogen generator.
Ah, but can it fully drive ev?
I saw a while back, as i know most evs are still fuel powered, that jeep had one that could just fully drive electric as u could charge it so u didnt needda fuel it up
It can, as long it has battery.
Ah so u can just hit a switch so it wont turn on the gen?
That's a plug-in hybrid, a mild-hybrid needs both engines working.
Sadly the Mirai is automatic, but it won't start consuming hydrogen as long it has a charge.
Not to mention the hydrogen generator is as powerful as the engine from a small town car, while the electric motor has 150HP.
So even if u fully floor it , it wont be like: switch on the engine to not deplete the battery?
You hear the hydrogen generator kick in, or well I do, but it's way after you floor it.
Although flooring any Toyota is like waiting for a snail to walk
It's still faster than a VW Polo though
Well the one i drove, it did like 60/70 on the electric, but i assume all hybrids have the electric drive train tough as the engine is mostly to power car and charge batterys but as ev bit
So it went to accelerate quite nicely then engine kicked in and no different
Eh, they can be reasonably peppy. My little Pontiac Vibe with the 1.8 moves okay. As long as I don't have too many passengers in it... (somewhat accurately described as a rebadged Matrix.)
I one time drove my car filled
So basicallyt 5 people
2adults in rear and a kid, 2 in front
Just with the two adults and kids i noticed it before driving off as it was sagging
I know, but ly Mirai has instant torque because it's basically an EV
5 people in a Mirai, I wish that was possible
Iāve got a 9 year old hybrid that I actually love. The pedal and response is a little mushy compared to a traditional ICE set up but it can hold itās own quite well. Not to mention how nice it is on my wallet
I don't put enough miles on my cars to get any worthwhile savings with an EV, IMO.
I'm practically at "oil changes once a year, whether they need it or not!"
If thatās the case then an EV might make more sense in your situation
Meanwhile i'm putting 100 miles per day on mine
I'm probably averaging less than that per week.
So you're putting less than 3k miles on them per year?
@hollow knollyeh my diahatsu aint big but it fits plenty
Currently its used as a garage for my window cleaning stuff as i no longer use the car really as i use the tuk tuk
But its basically used as a van while it isnt one and it works quite well for it, im just glad i managed to find a roof rack for it took me a long time to get one for that being a used one as money adds up, but yeah, i wish i got so much work im having all water jugs filled and it meaning i got so much work for a day im making baller and it being worth grabbing the car vs just tuk tuk and a few of the can
Ballpark, not far off from that.
Also as i like how it sticks out and people know i the window cleaner drive it, it already meant last weekend they went looking for me as they wanted theirs cleaned too and saw my ride
probably 1/3 of that in the last 6 weeks from two trips...
Then yeah you should be good with what you're doing now
The total yearly fuel costs probably are still cheaper than the amortized difference in price between ICE and EV.
I work from home, and we don't have to do much distance driving day to day. If the cost differences come down more, or fuel costs go up significantly, the math could change. But right now? Makes no sense for me to use an EV.
For me any car preferably EVs with enough assist is nice, my ADHD is literally putting me to sleep in ICE cars because they're so loud.
We ll yeah, as if u look at the range of new modern cars and their price to acquire vs electric, and then looking if u where to drive and fill at a gas station or recharge at electric, the gas car if u look at it is gonna be just as cheap to fill, if u just stick to highway fueling and recharging, but the purchase price is cheaper
For example for me it makes a lot of sense, Hydrogen is ā¬10.- a kg, electricity around ā¬0.30 a kw and fuel is ±2 a litre.
Plus a minute to refuel time wise is cheaper than 30mins
I'd recharge at home if I had an EV. Not difficult to pull permits and run wiring.
If I had an EV I charge it overnight or at work.
Yes tehn it be worth, but if u look at it from a drivin point where u drive far and shit daily, like a work car so to say, ev is shit
Depends on how far, of course.
It's a breeze, we have charging point almost everywhere.
Yes but the time it takes vs gas
I go to work and have 400KM, I go home I have 400KM
From a business standpoint though, downtime to charge is EXPENSIVE.
I work 8 hours in the same building, enough to fully charge a car
'cause you're paying the driver the time they're sitting there waiting.
Yea for that kinda traffic theyre great, but im more talking if u aint got a office job and do electric theyre kinda shit, with most my work, even if i where to drive a person ev not a van for instance, most times it means it will be fully drained end of each day if we were to drive far with em, we getting ev as trial due to rotterdam saying they bannng diesel company vans , so yeah that aint far, but for long distance they gonna be shit
Delivery companies here have for that reason 2 EVs per person
And that's a HUGE capital expenditure.
Should make ev vehicels with the battery pack being modular, port i work in the robot vehicles just go in bay when low, battery be pulled out and gets swapped, probably also cheaper to have a station for that than having two vehicles per person, plus it means two minutes swapping bat instead of van plus cargo
That's interesting though. I would think if that's such a big thing, two vehicles per driver, companies would be pushing more for swappable batteries
I used to drive an electric forklift for a bit back in the early 00's. Swapping out a few thousand pounds of batteries took about 45s once you were at the front of the line.
Yeah the port im in the agvs, the battery is like half the size of a smart car, and within 5mins idk its swapped over, by a robot, it aint fast but for that size batt and weight yeah duh, but those tiny cars and shit, heck the dhl electric vehicles here are half the size of that battery so they cant be that big heavy that it takes long, i mean my old job forklift we had two batterys, took me 2mins to swap with a handjack
Yup, as its just a put forks under that have the tray on it for the battery, pull one out park grab the other one and slide it in
Bet for those cars it could be done that way too, but if wanna be fancy u have a tiny drive trough thing with a agv that pulls it out, but even manually its easy, just one plug and it being in by weight, for the cars probably want a lockng mechanism but even then, the dumb postal drivers we have here can even do such
Had a giant pneumatic / suction setup to pull the old battery out, stick it on a shelf next to a charger, and put a new one in.
I used a pallet jack, batterys had a thing on so u could pallet jack underneath jack it up a inch, unplug and pull it out
It's cheaper than constantly refuelling the gas guzzlers they had before.
Thinking about it now, there probably were forks involved as well. It's been a while.
While an EV charges like twice a day, the older vans have to refuel at least 3 times a day
Older vcans? Well i worked and we had delivery van too, that van would basically be fueled at end of each day so it be ready, but they could run two days on a tank, even old vans do what, 400on a tank/? Thats more than enough for one day of delivering
Well its either u can change it during day its a side unlaod, but the other option is lift it out from above, and those aint the replace when empty during day so u can charge it and use a spare type
Yeah, slide out the side is what they were.
The deliveries they do is constantly stopping, sometimes they don't even drive 500m and then have to stop and drive again.
This apparently costs the most fuel.
Well i mean not if u drive normal, but they fucking floor it to 60 and brake hard in that 500m and will let it run for the whole day even if they have multiple adress in one stop
And dont bother to take a extra step but will drive the van
Cant say they drive normal looking at their vans
Dude, they drive faster than me, and I floor my Mirai
Exactly , that way i can see they use a tnak a day, but 3?
3 tanks a day sounds like an exaggeration.
My van was loaded and had ladders on top and did 120km to and back at 140non stop and it didnt even run the tank empty in one day
So no way they use more than a tank a day, heck even with their driving and letting it run full day, it doesnt use a full tank as i taint loade to the brim with max weight, as where iworked the movanos got max weight on each trip and they did 4/5a day and be over eveh
Trust me, the depot is like passing half the country, because why store it in the depot nearby
Thats a lie
Nope, last time my package came from across the country
Theyre near, but thers vans that go to big depot to pick up the packages in evening and bring to be sroted or pick up for the morning delivery
Yes it does, but that doesnt mean the van is doing that
As it goes by cart, its either a boxtruck or a actual truck driving from the big sorting to the depots and back
I only ever seen a DPD truck, I never seen their vans, and DHL vans are usually freelancers, so unmarked
And usually those vans are partially falling apart
Usually? They always are, never seen one that aint unless it just got into their posession lol
Oddly enough the company owned vans have the least scratches, the personal ones are falling apart
Idk where ur based, but it seems tnt vans usually are the nicer ones, unless its a claer van from em but just have a round logo instead of the full wrap ones, the logo ones are subcontractors, all vans be ruined
I haven't seen TNT in years, usually PostNL(the 1 that's 99% on time), DHL(That doesn't feliver to your door 70% of the time because you "weren't" home) and DPD which is as good as PostNL
Yeah its the same thing, i just say tnt]
Dpd is shit, dhl tries, dpd just drives past and says they tried, altough dhl sometimes pull that ,but their delivery is across the street from me if i miss, but its just dpd is shittiest
Also non ever are on time, and if they are they barely are at the end of the time frame
That's not really a thing. And even if it were rusted to hell somehow in less than 300k miles, the U joints in the thing would have been crunchy long before that. And even when those ARE failed, the thing so turns. It's just extra crunchy.
Get back to work u
Here DHL refuses to deliver on time and on location
Never in my life seen a throttle body that was sprung open and closed by the cable. There's no reason for it and flies in the face of basic design theory
Usually its most packages evening delivery, 95% of time even if diff driver its always around 7
I'm home
So it seems the evening crew got their shit together , day crew is something different
Go fix ya miata
Have a 600 rwhp miata.
But it cant drive
It drives just fine. Dude dailies it
I meant urs
Yeah, that.
I'm only waiting on parts lol
Project cars are always waiting on parts. Even when its working.
Corollary: every car that's old enough is a project car
Might fuck around and paint the diff housing today now that I feel better
I see it a lot it very old cars and even modern mopeds
Doubt. Give me one photo of a throttle body that's sprung open. That's the dumbest thing you could do.
Engines idle when the tb is closed and should never open on their own.
There's a reason it's called a return spring. And it's to return it to closed.
šæ
š
Sounds normal
I own a vehicle from the 1970s and have worked on much older. Only the Model T didnāt have a return spring and thatās because it was a lever throttle
And all of them if the cable snapped you would just take the steps to take it out of gear and turn it off
Maybe it's a Europe thing, but it's been years ago I even worked on an ICE vehicle, let alone driven 1 extensively.
Well my first experience with vehicles was shit from the 70s onward and I've never seen it and it flies against all engineering education I've managed to complete
Why? Because it makes zero sense.
If the tb is pulled open by the spring then the cables has to pull out closed.
What happens when you pull on a cable that's already pulling a tb closed... nothing.
It just pulls harder closed.
Then you could say well dummy you push the cable
I had the return spring on my carb snap once while driving over a mountain pass. Just meant I had impromptu cruise control until I got to town and could get a replacement at autozone
Cables aren't really designed for that.
You can push through a cable but that's also cable 101 to never do that because it'll bind in the sleeve.
I mean that I know, just not really easy on an automatic 
You just push it into neutral
Or well, never driven an automatic other than my Mirai, which more or less a single gear vehicle.
Wait, that's possible?
I thought it would be locked into gear
I can't even think of a way a spring-open tb would work with a cable.
"N" is usually directly adjacent to "D"
Most automatics you can bump through gears if needed. Just canāt slam it into park
Or shouldnāt
Yeah. You CAN lol
Probably snap that pin off in the process
You could also just slam it into a wall
Jump a coulee
shear the parking pawl right off, yeah
Anyone have any ideas for how a spring open tb can even work
I'm really trying to figure it out
You probably have your throttle pulled closed at start up and let it out to run
I canāt think of a situation you would want to do that though
Maybe on an Me-163?
But thatās a scary kind of special case
Conceptually there's nothing hard about doing it. Spring just attached the other way so default state is open.
Cable also attached the opposite way, so pull closes it.
And then, once you're at where the cable terminates at the gas pedal, you'd flip it from one side to the other.
(or don't, I'm not your mom. Then you'd have the fun where pedal on the floor means idle, and pedal released means WOT)
Physically there's no reason you couldn't, you'd just be stupid to do it
Or not so much stupid as there isnāt much benefit from a failure or function perspective in most situations
Maybe on a piece of equipment
Yes but all of that is stupid lol
I'm trying to figure out how to get it to work the expected way
If āthe expected wayā is on a gas pedal to the floor is open throttle then a lever and a second spring should do the trick
Really itās just a fail open design instead of fail closed
It could be so the throttle is lighter?
I personally wouldn't know, like I said, it's been a while I seen them up close.
That would be nonsense of course as Jimmy stated. Extra parts for a worse situation. It wouldn't make the throttle lighter. It physically wouldn't work
The thing you say is a thing isn't even possible without a second cable or a lever AND another spring. So you'd be dealing with a second much stiffer spring to pull the open spring closed.
Some do indeed have two cables but it's still spring-closed.
The throttle lever or whatever its called also has a spring inside, it's like the spring in the throttle lever is a bit tighter than the 1 on the engine block.
Nah. Not buying it. It still makes zero sense.
Not always. My cornbinder only has the spring on the carb
That's extra work for the same result and a stiffer pedal
The accountants would shit bricks
Companies are weird.
I have seen some weird ass shit.
From motorised bathtubs to 4 wheeled mopeds.
I mean you keep saying it but I can't comprehend a possibility. without making the situation WORSE, its not even possible to do that
a motorized bathtub, beer cooler, or barstool will all still be spring-closed, and I have seen 2 of the three.
done many laps around a campground on a beer cooler with an engine.
But, have you lived in the Netherlands?
Iāve visited and none of the vehicles looked out of the ordinary there
are there any vehicle manufacturers there that arent owned by major players
and yet mass produce commonly available vehicles
I think DAF is Dutch
The catch is that anything produced would most likely still need to be used and certified for use in the EU. And thatās more stringent than most US states. Because of that Iād be surprised to see a fuel body that was allowed to fail open
DAF, Spyker, Donkervoort, and then we have tons of smaller manufacturers that had faulty throttle systems in the past.
Post pics
Should be easy to Google up any throttle body from one of their engines
Pretty sure the battery in my miata is shot now too.
I have no idea how to even search stuff up that has anything to do with an engine, all I know is I had weird shit in my hands before when helping people.
I am not gonna make pictures with oily hands
Car make and model throttle body. Takes 2 seconds
I don't even remember the cars I did stuff with, I saw them once then never again.
I helped people, seen fully disassembled vehicles, that's about it, I am unable to ask people what manufacturers they are if they don't understand sign language and my hands are too dirty to type.
That's bare aluminum.
no i mean weren't you gonna paint it safety red?
Yes. It is unpainted as yet
I couldn't possibly agree more on the stupidity of such a solution, when the obvious alternative, spring to close, has nothing but advantages in comparison.
Okay. I CAN think of some engines that when examined, will really seem like they're spring opened, and I have several of them.
Any small engine with a governor that sets it to always run at a set RPM. Generators is one obvious case. Some lawn equipment like a chipper/shredder. They'll still possibly have a spring on the carb that pulls the throttle closed, but the governor mechanism will have a stronger mechanism pulling it full open when stopped.
Never on a car though.
maybe? been a while since I messed with one, not sure they would want to start at wide throttle though
so I thought they dont open until the thing starts
i thought a vacuum or whatever pulled it open but its got like.. a regulator to keep it below a certain maximum
And the best part is just one stray gamma ray can do that
And those things are blasting through the earth left and right.
Extremely rare but without everything being checked and double checked a bit can be flipped anywhere in memory at any time and do that
It's way worse than just a single bit flip. Watchdog tasks that don't actually watchdog, telemetry logging (brake pedal and throttle pedal position!) that could log values incorrectly...Bunch of other stuff as well.
Here's the post from the source
https://embeddedgurus.com/barr-code/2013/10/an-update-on-toyota-and-unintended-acceleration/
So any time anyone thinks they can trust fully computerized things with no backup, this is the required reading.
Well. Yeah. But that's what started it and without any error correction the car dunks itself.
Though I will say the process of suing the balls off a company, despite usually being used for financial gain, was clearly applied here appropriately and the financial incentive definitely helped fund getting the root cause. That level of analysis must have been big bucks.
That kind of thing benefits everyone.
Indeed. One can only hope Toyota and the rest of the industry learned from it, but I have a hard time believing that.
Writing extremely robust code is hard.
Quick, shoot me some automotive usecases of an IR thermal camera, I finally have one :D
Finding exhaust leaks. Partially clogged cooling passages. Uneven brake application.
Cats overheating due to slightly rich mixture.
Looking for interesting stains on the inside. Eh, maybe better not to know.
Seeing how it looks like when u pee trough a ir cam?
So, wife has #1 loaded into van, ready to leave for a field trip. Calls me from the driveway: "brake light is on, what should I do?"
Big old puddle of brake fluid by the left rear wheel...
Looks like my day just got more interesting.
Hehe]
Very good ones, Injustice! Thanks!
Add āfinding hydraulic leakā to the list
Looks like it's the caliper, but not certain yet. Entire area was covered.
That would simplify things if thatās the case
Yeah, but it's a lot more expensive than a new line or the flex hose!
Which is what I was expecting
Still less than 100 for a reman so not a huge deal either way.
I packed up all my guns and tried to drive 3 hours with a buddy once. Spur of the moment.
Made it to the end of my driveway with no brakes.
Pinhole in the damn line.
Lol
So today is apparently brake day for all
I mean it was a few years ago
Ah
I mean, my tuk tuks front brake is going bad
But the rears aint so yeah, it works front but not much
Might just do some work this summer, stereo for one. And im thinking of pulling the diff oil out and putting new in
Fuckin diffs
Failing shocks
ac issues
whatās going wrong with your diff?ā¦
It's out of my car because I had a howling noise on decel. So now it's at the shop, my cover got welded reinforcement done and is getting repainted and oem competition bushings are going in.
How would I check for failing shocks?
A colder one probably isn't damping oscillations as much? Guess.
Hmm would not think they'd be heating up much. Also I'd guess every shock would react different in terms of heat
Well if it isnāt driving smooth Iād say, check the points itās mounted
work vans had catastrophic as it just fell trough , shitty handling and then just collapsed the front
I was talking about automotive thermal camera usecases to be clear xD
Well i dont think they produce lots of heat even if theyre screwed?
U could stress test and see if the temp is way hotter than a non broken one/wearing one
Shocks work by converting motion into heat
Ah, well i assume if faulty theyre either really hot or colder than the working ones due to it not doing its thing?
Failed shocks allow a bunch of bounce on the springs.
Bounce the car at each corner. If the thing oscillates up and down significantly rather than just coming back up and maybe a small bit of rebound at the top you might consider getting them checked by a professional.
It's kind of a matter of experience to know how they are behaving vs when they were new but the point is failed shocks just bounce rather than damp.
Aka ask mr fat ass to sit on it and wiggle his booty?
Nice
Miata of Theseus!
Nearly. I got a guy who can cut out, weld, and repair this little bit of rust now too. I'm exchange for my technical skill with... stuff
First order of business will be getting his cnc plasma table moving
So your gonna 3dprint stuff for him?
So what, u gonna test the kneepads on ur pants?
Owh
I seee

Some videos and pictures of things I've cut recently on the 4x4 scratch built plasma. Lots more on the way.
That
I know what a cnc is
But plasma
It's funny you say that, there's a person in the subaru discord that has a 240z they call the "Theseus' Z" cause there were about 8 donor cars that went into it, especially for the body work.
I'll find pictures real quick
8 cars for bodywork? Seems like he got one piece of body panel per car
She did pretty well on it (also correction it's a 260z)
I mean when it's a car from the early 70's, sometimes you just gotta find cars with 1 good panel to salvage
atleast if you wanna do it on the cheap
afaik the only body panel that is original is the roof
Gosh i love that model
Yep, i think the License plate also says Th3s3us
So sad that europe practically has no JDM cars left
Well yeah, replacing that will probaly compromise the structure quite a lot if done wrong, even if right
Probably better than it being rust dust, tho :D
Yeah
Idk the full story on the car, but it's one of the cars in that server that always brings a smile to peoples faces whenever it shows up
She's apparently doing similar things to a Subaru Outback rn
cause why shell out big bucks for a rust free Outback (which is unobtainium) when you can just make one rust free?
Lol no
Welds is welds baby
Your saying cutting off a roof wont sacrifice it?
Not when you weld the new one back on.
As i mean you are altering the structure
I wish, companies would rerelease certain oldies but like kinda redone
rerelease as in pretty much same body but make it modern
Chances are the new roof will be stronger anyways since the manufacturer likely welded less than the person replacing it would have
Even if u replace iwth new and weld on new i feel it still be comopromised and not like factory
Never said im right, im just asking mostly
If welds done at least half way correctly, it's harder then the base material in most cases
Some companies will put together single cars for rich clients if they're still producing parts for said cars.
Sadly not what I meanš
Also: most cars that people would love to buy, are already completely sold out in parts, because each not crashed one is being upheld pretty good probably
But you do have to remember that harder isn't always better when it comes to durability
Speaking of weldin
True - I meant that it takes greater forces to separate both sides tho
Saw a vid come by of a russian guy who died because he hit a pole with his supra and it waas cut clean in half, but apparantly they cannot import a full car, or can but super expensive, so theyll cut it in half and import both parts as parts
And weld together
Words be difficult
Wait the accident cut the supra or only afterwards?
Also: that had gotta be some pothole alright
It was apparantly imported as two pieces of a car for "parts"
So it was welded back together and afterwards got in a wreck against a pole, wich cut it clean in half but on the welds it seems, aka no z cut to get more area to weld, but it also had no cage or anything to reinforce it on suhc
Dont know much backstory just saw it come by but yeah
Anyways im signign off
Going to bed

Pole, not pothole
Ohh bruh
"While pretending to drive a fast car, something Civic owners have a lot of experience with"
much burn, I love it
hey, sometimes it's fun being in a little manual car with 0 hp, cause then you can full throttle everywhere and feel like you're going fast without endangering anyone
oh yeah, a lot of people say its more fun to drive a slow car fast, than a fast car at that same speed
it's why i liked the manual scion ia (became the toyota yaris sedan, aka a mazda 2) my parents used to have, with it having the 2016 MX5's gearbox, 100hp, and 0 torque all to the front wheels
but that was roasting Civic owners specifically rather than slow car owners š
Funny my car is also 100 hp but all of it is torque and all to the unloaded rear wheels
Owh yeah drove tiny Toyota Yaris
That was fun
Turbo no rpm counter and blaring engine
entirely different car
this was a rebadged mazda 2, so think a sedan version of a chevy spark that only had a manual cause it was cheaper than an auto, no turbo, no engine sound at all even when you floor it
which kinda sucked cause you had to stare at the tach to know where the revs were
Yeah my car does 100 at 3k rpm
When I drove work van I usually listened to rpm for my car due to speed
But my van i was doing 130 and it didnāt hear it yet
that's one of the many reasons i prefer manuals, you know what speed you're at cause you know what gear you're in and the rpm of the engine
in a decent automatic for everyday use (ie not thrashing it) you dont even need to know the rpm.
How do I read manifold absolute pressure lmao
Does average idle map change from engine line to engine line or is it consistent from engine to engine
And is the pressure just literal the pressure in the manifold, meaning to calculate the vacuum it would be atmospheric pressure - map
"how am I driving, how does a car even work?"
Absolutely - depending on layout and losses of these layouts the timing and injections vastly differs!
Readout absolute pressure or measure as in temporarily know this value?
There's pressure sensors for the manifold but they're usually only installed on boosted cars. All other ones mainly work with a form of MAF (Mass Airflow Sensor)
most cars these days use MAF and MAP sensors
Actually most cars are switching over to MAP sensors
every car I have dealt with thatās less than six years old has had a MAP and MAF sensor
you get a much more accurate picture of what the engine is actually doing if you use both. this allows you to run closer to the limits of what chemistry will allow thus allowing you to solve various emission issues with maximising fuel economy
Most cars have turbos nowadays tho so I think the need for efficiency answered by turbos came first :D
On my old bag o' screws the MAP is approximated by the ECU cause of a lacking sensor
Tell that to Mazda, they answered by natural aspirated 2L to 2.5L engines and carefully adjusting the timing to be just right.
And they're almost as efficient as turbo charged 3 cylinder while having more power.
Huh okay damn
If they are the engines Iām thinking of doing theyāre far less flexible in the low rpm range making them less fuel economical in the real world
They actually are very good in the low RPM, you also have the low end torque a turbo charged engine doesn't have.
Erm.. that sounds like totally wrong!
Small capacity turbos have ridiculous amounts of torque equal to 3 or 4 L engines at about 1500 rpm
Not the ones I have driven.
So my 3cylinder 1.5l has 290Nm at 1400 rpm through to 3600 rpm but tops out at 112kW at 4300-5000 rpm
Isn't that the Brabus smart?
Git gud
There's a front engined mr2 in my town that I've seen a couple times now
š¤
But why
Drove 120 miles today for a car show in the Camaro.
Hot
Yes it is, especially with a black interior and leather seats. And no AC.
Seriously though, thank you.
I think that's the first IROC i've seen that I actually really like the look of
what are the head lights?
they look like the should be the old sealed beam but it looks like you got LED ones
Headlights are from Mormito I believe is the name of the company. And yeah, they are 5x7 sealed beam conversion to LEDs. They are super bright.
Each unit was $250, so $1000 for just the headlights. The fogs were another $200ish, and then the new turn signal lens were $100. The bulbs are all LED and the turn signals use whats called Switchback bulbs from Diode Dynamics. Where they are white running lights but turn orange when the blinker is used.
so 6054?
not to bad for led ones good thing I only need 2
still more than I want to spend though
this is what I have looked at getting a fair bit cheaper and with an 8 year warranty
Yeah I found the ones I bought. I was wrong about the price, they are $270 a pop, and I have 4.

This is why I wanted hem though. Low Beam
High Beam.
very nice
my curent ones are so dim that if some one is behind me I can't see my own headlights
I "Need" better head lights but 200+ is a bit of an ouch
Yeah same
Gah damn that Camaro is in great shape. It's weird to see older cars in really good shape like that.
Heard about the diff. Apparently they didn't immediately find anything wrong with it. So I have to talk to them tomorrow.
Look out the window to my left
See a nice looking cab over classic truck, might be American
Cab over? No lmao.
Well you guys used to
If it's a smaller truck idk what it is but we made cabover semis for a while.
Owh it was a full size truck
Im not too knowing and it wasnt fully lit but it might been a freightliner or such
The combustion engine will be phased out in Europe from 2035. Apparently climate neutral but astronomically inefficient e-fuels have entered the zero emission transport debate and now, thanks to a few choice lobbyists, they may form a small part of the powertrain mix after the 2035 phase out. In this episode we ask what is an e-fuel, what makes ...
Still waiting on my diff. Wiring for the trailer is done, but I need to mount it. Then I have to sort out my stereo as I ripped all that apart again.
Not me accidentally nearly getting two insurances for my Car š
... The new plan starts in 8.5h and the old one isn't technically cancelled yet
Eh. I do that almost every time I change.
Jack takes a spin in the new Ferrari Testarossa J: a creation of the Bicester-based Little Car Company. An officially licensed Ferrari product and obsessive recreation of one of the greatest and most beautiful racing cars of all time, is this just a rich person's plaything? Or something more significant entirely?
00:00 Not quite what we expecte...
Heck, probz can get them legal here on moped license lol
In EU you can get them legal, but with a car driving licence as they go faster than 45KM/h.
This is what I'd imagine Double_Taxman like if they hadn't told me that it's not fast xD
Already saw that
Dont worry, ive bene thinking about buying another one thats a beater and fix that up and shit and swapping engine
But i got no shop nor experience
I'd say thats the best way to get some xD
Tools and crap be expensive
