C7 stringray mods

[lethal bison]

How much can i push with a base c7 without engine/clutch/transmission issues? I just dont wanna swap the major components if possible and my goal is around 800hp

[honest cypress]

there's usually a lot of potential left on the table just from road conditions and the driver.

take a few track days and some coaching lessons, you'll find that you're leaving a lot on the table as is.

there's also a fair bit of performance to be had just in maintenance, good tires and proper brake pads.

once you're really pushing it suspension, wheels and a tune can bring out more performance but without a solid foundation they won't add much if anything at all.

there's also weight reduction which is quite common however that usually comes with cost and a worse quality of life when just driving around, exception being if you're a big fella and loose weight on yourself.

[lethal bison]

Im not really lookin to make it a track car, more as like a nice street performance to race other ppl in. Ive heard that my engine (lt1) cant really handle any boost and more so just bolt ons. I understand that me driving and roads matter a lot, however i feel like ive done everything i can as a driver to maximize performance along side also driving safely. I still feel slow and left behind when doing pulls.

[honest cypress]

everything I said is with the street in mind, if I wanted to suggest for track I'd say stuff like fixed buckets, cage, aero, carbon ceramic brakes, slicks or track tires so on so forth.

adding boost is also a big job, lots of time and money.

what sorta cars are you doing pulls against and in what situations do you feel slow?

[lethal bison]

So ive been asked to race a couple cars

M4 comp g82, hell cats, z06s

Mustnags 5.0s and overall just wanna be faster than a z06

Also audis too like the a4, rs7 etc

I just feel like i got something to prove as if im a v6 mopar in a group of v8s

[honest cypress]

so boosted cars with a lot of straight line performance.

I wouldn't use other cars as a metric for your own speed though, unless you're actively compeeting on track it's meaningless and dangerous.

you have nothing to prove, just enjoy your car

[lethal bison]

Im not lookin to sc or turbo, maybe just boltons and a stage

I got funds and id say im a decently safe driver, i just wanna know if its possible to reach 700 to 750 hp w no boost

[honest cypress]

@sinful rapids you was gonna build your C6 for power on N/A wasn't you?

get in here and be active in the community for once

[lethal bison]

Ive heard that some boosted lt1s can blow up or have transmission problems, so kinda wanted to avoid the pricy road

[lethal bison]

U mentioned about weight to power ratio, is there a calculator for that or a chart i can reference to see like my weight to power ratio compared to other cars?

[brave steeple]

GG @lethal bison, you just advanced to level 4! Chat more to level up and earn top roles!

[honest cypress]

you just take your current weight and divide it by your power or vise versa.

HP per KG/LBS or LBS/KG per HP

[lethal bison]

Ohh so like 460hp/3500lbs?

And like if my numbers higher its better?

[honest cypress]

my car for example is 1000KG, has 67HP so 1000/67 is roughly 15KG per 1 HP

[lethal bison]

Ahh i see

[honest cypress]

pretty much yea

[blazing echo]

I am unsure if a lt1 can handle 800hp on stock internals. A quick google indicates fuel system runs out at 600hp and internals at 700hp. Trying to push as much power out of stock components is not reliable and you are only setting yourself up for component failure.

The whole premice of you wanting your car to be faster than a m4/hellcat... is hard to be sympatetic to. It is all a dong messuring contest and there will always be a car thats faster. A c7 is in the disavantage anyway since its manual and rwd and will always loose a dragrace based on grip and shift times when you enter the 500hp+ relm.

Build the car properly or let it be with some basic bolt ons.

[lethal bison]

Does it prove that its fast? Like if i put a car thats 15kg/h to a 12kg/h will the 12kg win for sure? Or is that flawedv

[sinful rapids]

Im honestly not keen on the lt platform since all ive ever had are ls motors.

If you want your car to be at all reliable then dont mod it. 800whp from an NA motor is pretty insane especially on an aluminum block. That kind of power NA is more for much stronger iron blocks.

Besides that, idk what transmission you’re running but with that much torque I wouldnt expect it to be reliable either

[honest cypress]

very flawed

[sinful rapids]

If I were you I’d cam it and be done with it

[lethal bison]

I am planning on upgrading my fuel pump, and mostly doin rolls rather than digs

[sinful rapids]

On an LS3 its like a 50-100whp bump depending on cam specs and thats perfectly fine with stock internals on aluminum blocks

[lethal bison]

Understoof thanks

[sinful rapids]

The manual transmissions are also perfectly capable of that much more torque

[blazing echo]

They use the same transmissions as BMWs right?

[sinful rapids]

Ls platform bettes use the t56 idk abt c7s

[honest cypress]

if we're talking digs then tire and driver skill matters a lot.

weight can help especially once you hook however has little meaning at higher speeds and no meaning on top speed.

rolling it'll be largely getting a good powerband and sticking in it

[lethal bison]

Ignore the check mark, is this doable?

[sinful rapids]

T56 should be capable of 600lb ft no problem and I doubt they downgraded the transmission for the c7

[sinful rapids]

Yes

[lethal bison]

How much is it to upgrade my engine

[sinful rapids]

Several thousand dollars

[lethal bison]

Would it be better to just get a crate motor?

[honest cypress]

don't 2step, really bad for the engine and to my knowledge something usually done in turbocharged cars

[sinful rapids]

2 step is so cool tho

Oh but also if you delay the timing and are 2 stepping, you might ruin that valved exhaust you want to install

[blazing echo]

Why would you want 2setp in a naturaly asperated car?

[lethal bison]

Plz ignore the weird stuff, is the performance parts realistic without having to engine swap?

[sinful rapids]

Shoot big ahh flames ofc

[honest cypress]

it is cool under the right conditions, so is doing a fat burnout when launching.

doesn't mean it's a good idea XD

[lethal bison]

Ok got it, no 2 step

[lethal bison]

I heard its for launch control

[sinful rapids]

Definitely the better idea if you want it to be reliable

2 step on its own is fine

2 stwp for launch control is fine

I thought you wanted to blow flames

[lethal bison]

I did

[sinful rapids]

You do that by delaying timing

And 2 stepping

[blazing echo]

In an NA car its just a secondary rev limiter. But since NA cars have instant power you might as well mash the throttle on clutch dump.

[sinful rapids]

2 stepping without delaying timing is perfectly fine but it wont blow flames

[lethal bison]

I was lookin at maybe getting 3 maps and the possibility of changing them on the fly: flame/pop tune, performance tune and quiet tune

[sinful rapids]

You dont need tunes for that

One performance tune is fine, and a valved exhaust will control how loud your car is

[blazing echo]

Crackle/pop 🤮

[lethal bison]

What about like a stage 2 tune?

[sinful rapids]

That means nothing

[honest cypress]

I reckon if we're talking a drag build that's street driven we should get Bsteg in here or Kawasaki, maybe invite this guy to the dragy server?

[sinful rapids]

That is a buzzword that can mean anything. A marketing term

[lethal bison]

Yeah i know, but i thought it was just cool showpff kinda thing

[blazing echo]

Thats why its 🤮

[sinful rapids]

You can do this with a timing module but again its going to hurt your car

[lethal bison]

Hahaha sorryc i wont be using it often dw

[sinful rapids]

What wont hurt your car is burbles tho

[lethal bison]

Burbles hurts the car?

[sinful rapids]

Burbles will happen naturally

[blazing echo]

Burbles belong in the stomach

[sinful rapids]

I like them

[lethal bison]

I see ok, awesome

[sinful rapids]

You can even get plenty of burbles on a stock tune with just a new muffler and a resonator delete

[chilly shore]

Na car with 2step

[lethal bison]

So just a stage 2 should be fine, with valved exhaust system

[sinful rapids]

Its sick for shooting flames

[lethal bison]

What about flames?

[honest cypress]

big V8 burbles can be fine, me and BSSB are used to small Euroboxes with burbles... it's nasty

[sinful rapids]

No flames without hurting your motor

[lethal bison]

In what way does it hurt the motor?

[blazing echo]

Rather see a 1,6l 4 banger shooting flames than a c7

[lethal bison]

Like do i have to get a new motor after a certain amoutn of time?

[honest cypress]

civic style

[chilly shore]

Its nothing crazy, I ran insane 2step on my stock 2 liter car for 2.5 years

[lethal bison]

Also, from what im seeing, everything on my list should be fine right?

[chilly shore]

Making 2x power of stock unopened motor

[blazing echo]

Shooting flames is not great for the engine but in stock form its safe enough. When you start tuning and upping power you will get issues longterm.

[blazing echo]

Not all engines are audi engines.

[lethal bison]

Without affecting my main components too much

[sinful rapids]

You delay ignition letting unignited exhaust gas into your exhaust pipes then igniting it

The first thing to go will be your catalytic converter

[lethal bison]

I dont think imma have that at all

[sinful rapids]

Then after that your exhaust valves will burn

[lethal bison]

Oh…

Is it ok if i just shoot flames for like a rev or 2 and then turn it off?

[blazing echo]

Not how it works

[chilly shore]

Very true but id hope a V8 designed to be a sports motor beats out a I4 designed to be in an econobox

[lethal bison]

Cant i change a tune on the spot?

[chilly shore]

Your also not really gonna spit much flames without being catless

[blazing echo]

The valves/cat get burnt DURING flameshooting, not after.

[lethal bison]

Ohhh i see

So prolly not a good idea if i wanna get expensive exhaust

[sinful rapids]

That will also damage your car

[lethal bison]

😭😭why is it so fragile

[sinful rapids]

Well your exhaust system doesnt like backpressure

[lethal bison]

Alr no flame tune

[sinful rapids]

Your engine is designed to push air thru one way

Not have air pushed thru reversed

[lethal bison]

Ahh i guess thats fair

[sinful rapids]

By shooting flames you’re creating massive backpressure and your valves will get fucked

[lethal bison]

Also is ecu tuning the same thing a stage tuning?

[sinful rapids]

They wont seat correctly and then boom new top end needed

[lethal bison]

Ok ill just avoid falmes unless i get shit exhaust

[sinful rapids]

There is no exhaust thats meant for shooting flames

The exhaust isnt what you have to worry abt if you have no cats

The exhaust valve is a part of your engine

[lethal bison]

Ohh

Can i replace it? If so, is it expensive?

[blazing echo]

Stage means nothing. Its a simplified term to describe how much effort you have put in modification.

[sinful rapids]

Its expensive

[lethal bison]

Okay so no flames

[sinful rapids]

They have to take the heads off your motor and possibly replace the heads

Which are expensive parts

[honest cypress]

yes but no.

stage tuning is nothing but marketing, a term companies will use to advertise a set of mods which could include an ECU tune.

meanwhile an ECU tune is just a tune of things like fuel, spark and boost if you have forced induction.
can also dl timing if it's variable but otherwise it's done by physically changing the system

[sinful rapids]

No flames, 2 stepping without delaying timing tho to create flames is fine albeit pointless

[lethal bison]

Got it👍👍 also is stage 3 good for daily?

[sinful rapids]

Stage 3 means nothing

There is no standard that defines what stage 3 means

It can mean anything

[lethal bison]

Ok then like a tune that makes my car the most power efficient and i dont care about fuel consumption

[sinful rapids]

We’d need to know what that actually entails

[lethal bison]

Is there like no defined limit/power to the different stages?

[sinful rapids]

Well do you live somewhere that has easy access to e85? Not all states have e85 gas

[sinful rapids]

No

[lethal bison]

Im in canada

[sinful rapids]

Does your city/province have e85

B.C. Probs has like zero e85

[blazing echo]

^

[lethal bison]

Theres e85 like 50km away from me

Its a very nice highway drive and thats exactly where im at

[sinful rapids]

Id stay away from that then

[honest cypress]

stages once again have no definition, meaning or consistency.

stage 1 could be anything from a new ait filter to a full on custom engine rebuild and stage 3 could be the exact same thing

[blazing echo]

You will be out of fuel by the time you get back from filling up

[lethal bison]

From tuning?

[sinful rapids]

Again id just cam the car, get a valved exhaust, a tune, and be done with it

Oh and long tube headers

[lethal bison]

OHHH so stages isnt just the ecu part, its everything including bolt ons

[brave steeple]

GG @lethal bison, you just advanced to level 5! Chat more to level up and earn top roles!

[sinful rapids]

E85 burns way faster than normal gas

[honest cypress]

yea no, way to far just for fuel and you get far less range when on E85

[lethal bison]

Should i still get an e85 converter?

[honest cypress]

depends on the shop, they are pure marketing

[blazing echo]

People only tune for E85 in places where ever single station has E85

[blazing echo]

A what?

[honest cypress]

nope, not worth it

[sinful rapids]

A flex fuel kit

[lethal bison]

Wait so what does tuning mean in ur sense

[honest cypress]

I assume they mean a flex fuel kit

[lethal bison]

Got it yup thats what i meant

[sinful rapids]

Taking your car to a tuner and getting them to tune it on a dyno

[blazing echo]

Thats normal since north american E85 is very hit and miss.

[honest cypress]

or a street tune, harder to do but from what I've heard they're often a lot nicer and better on the streer

[lethal bison]

Whats the difference between?

[sinful rapids]

Idk what a street tune is I wouldnt trust a tuner that isnt using a dyno to measure their success

[lethal bison]

Okat noted

[chilly shore]

Yeah mine pops around 480whp

[lethal bison]

How much is that in hp?

[blazing echo]

Dyno will be healthier for the engine since you can go though the entire engine map

[chilly shore]

500+

[sinful rapids]

Depends on the car and setup

[lethal bison]

Damn nice

[blazing echo]

My car got 170hp

Weights like 1000kg

[lethal bison]

Okay so, rn, list would be, cam, headers, exhaust, dyno tune, and as much bolt ons as i can

[sinful rapids]

Camshaft, KOOKS LONG TUBE HEADERS, and a valvetronic valved exhaust, dyno tune

Dont buy any long tube headers besides the ones Kooks makes

They are the best

[blazing echo]

Find a tuning shop. Say you want a 800whp to beat hellcats and let them spec a build for you.

[lethal bison]

What about ahr? I heard the long tube headers are very good

[lethal bison]

Thats what i was thinking, but i dont wanna get rippes off or scammed

[sinful rapids]

Idk

[blazing echo]

Choosing preformance parts is dificult enough when you know what you are doing.

[lethal bison]

Ok ill go for kooks

[sinful rapids]

They will give you a dyno sheet which measures their results

[honest cypress]

a dyno tune is done indoors on rollers.
the car is strapped down and has a simulated load as they floor it trough the whole RPM range adjusting factors as they go until they get what you want.

street tune meanwhile is plugging systems in and driving around both normally, pulls and top speed runs tuning around that.

basically one simulates real world but is far more consistent and easier to work with.
the other one is real world and less consistent making things a lot more difficult and very hit or miss

[chilly shore]

Damn

[lethal bison]

Ohh gotcha, thanks for the explanation

[chilly shore]

How to get ripped off 101

[lethal bison]

Whats a drag pack?

[chilly shore]

Do your research, learn what parts are best and only have shops do manual labor.

Don't have shops spec out everything

[sinful rapids]

For 800who you’ll need more than what you want imo

[lethal bison]

Can it be trusted?

[sinful rapids]

800whp is not for people like you who are uncomfortable with cars

And uncomfortable with reliability issues

[lethal bison]

Ok realistically, imma go for 700-750hp

[chilly shore]

Get this man an exhaust intake and tune and he'll be good

[lethal bison]

Not whp

[chilly shore]

That's faster than supercars btw

Most

[sinful rapids]

Exhaust, long tubes, cam, and tune

[chilly shore]

What is a Stingray c7 stock hp

[lethal bison]

Ok done and noted

460 and i have driven 1000+ so im not too worroed

[sinful rapids]

Just make sure whatever cam you buy doesnt need anything extra like new pushrods and stuff

[lethal bison]

Also couple more questions, is it possible to have a blackout switch behind the screen of the c7?

[sinful rapids]

Nothing too aggressive basically

[lethal bison]

Thanks, noted

[sinful rapids]

Whats that

[lethal bison]

Or just a thing that can turn all the lights off in a car?

[sinful rapids]

Every car has that stock

Lmao

[chilly shore]

Also procharger > Turbo/supercharger for the c7

[lethal bison]

I cant turn it off while driving

[chilly shore]

Like 5% less power but literally half the price

[lethal bison]

Ill keep this in mind too

[lethal bison]

Also, why not get the pushrods? Wouldnt it give more power?

[sinful rapids]

Its just that it also usually entails other new valvetrain components

More money and less driveable in all likelihood

[lethal bison]

Oh ok 👌

[chilly shore]

@lethal bison are u versed with stuff like what antilag is, diffrence of turbos vs blowers, how tuning works etc

[lethal bison]

Nahh not really

Id say im still quite new the all the car stuff, i just got into cars since jan

[chilly shore]

So much useful info

Obviously not an LS motor or building a drift engine but still very useful knowledge littered throughout

[civic geyser]

Holy hell this thread got long haha

[late reef]

And in the end, the OP would be far better served by posting these questions on a dedicated C7 forum...

[civic geyser]

Agreed lol

[lethal bison]

Im in china rn, the forums block on vpn

[lethal bison]

Thanks

[late reef]

Ahhh Gottcha, I've had trouble with sites (generally commercial entities) that block VPN as well. But never to a car forum.
I'm using Nord and getting here just fine. corvetteforum dot com

[honest cypress]

@lethal bison I can also suggest some YouTube channels for you, specifically I suggest Driving4answers and engineering explained.
