Camaro V6 Challange by Subaru WRX - Page 5 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

First, a 2010 WRX will eat you for breakfast.. if he's modded your brunch as well.

I have a heavly modded Cobalt SS/SC, and I have a hard time beating a 2010 WRX. I also want to point out that i'm faster then a Stock Camaro SS... If it's a 2011 WRX, it is faster than a STi in a straight line. again you will loose.

Granted... I live in Denver and Elevation plays a HUGE role in this... Anything NA here looses a LOT more power then a boosted car does.

Second, he NEEDS to be tuned.. DO NOT, I repeat, DO NOT let him boost without a tune... he WILL blow that motor... Boosted cars rely HEAVLY on the computer system.

He probably already cracked a ringland to be honest.

I dont know nothing about subarus guts but i told him and he was pist lol.

To be honest, if your friend had no idea that he needed to tune after modding his car, then he is a idiot... It's soooooo easy these days to get information on MODs... I mean the internet is FILLED with WRX / Subaru forums, with lots of knowledgale poeople who are usualy more then willing to give advice, when someone wants to start modding their car.

The first step someone should make before adding performance parts to a car is RESEARCH! That's the main reason these forums exist... so people can ask advice about their car. 9 times out of 10, someone has already done XX mod to their car.

EDIT: So I reread what he installed... and it appears to be just an exhaust system... that shouldn't require a tune (helps, but not nessasary)... did he install anything else? Such as fuel injectors? did he turn up his boost? Did he reinstall his o2 sensors? if he did not... his car could have gone in "limp" mode.... I'd have him stop by his local auto parts store and borrow a ODBII device, have him pull any engine codes, than tell him to sign up to a WRX forum with the codes the ODBII device gives, and post up.

I dont know what all he installed but when he needed my help we removed old bolt on system from headers down. It was painful painful hours removing that crap. After that the next day and you know what happen. I havent asked him yet.

Hellfighter · 08-21-2011, 01:09 PM

Anyways i always thought you require a tune after exhaust system install, Like on my camaro mine is a a catback system and i will be purchasing new headers and a throttlebody along with wheels, that will make the car different than stock, and was thinking getting Trifecta tune like i posted earlier to even it all up so u get more Power from fuel ratio but making it a 1 to 1 to still be legal. Anyways that why i thought your always required to tune so its stays balanced and does not Eff your engine up.

if you doing just exhaust / intake, it is not required to have a tune, as it wont blow the motor, you may through an engine code as you are adding more air to the exhaust system... A tune does help in reprogramming the ECU so that you wont through CEL, and it will adjust your timing so that you are getting the most out of your exhaust.

Also good call with Trifecta, i'm currently tuned by Vince myself on my Cobalt, I like his tunes as they are more on the conservative side, so there is no chance of getting to lean of a tune.

Edit: also, you don't need a tune for your wheels

All motor V6 cars generally do not require a tune with just bolt ons. You will however get more out of your headers with a tune. Turbo cars are much different.

The only time we really need a tune is for large nitrous shots and definitely forced induction. Though you can even get away with a large nitrous shot and no tune, SOMETIMES.

A downpipe alone NEEDS a tune on these engines. This is not a naturally aspirated engine. Running a downpipe, especially if it isn't catted, will influence the O2 sensor readings and remove back pressure from the IWG allowing overboosting and lean AFR's. With headers, if they are equal length especially, you're just going to increase the intensity of those problems. This guy needs a tune badly, if not only because the EJ255(WRX)/EJ257(STi) are so sensitive to knock and boost creep/overboost.

So did you guys replace the gaskets to the up-pipe (and from UP to turbo) and the cross pipe? He could have a big exhaust leak pre-turbo.

Hellfighter · 08-21-2011, 02:47 PM

Hmm i am not sure about the gaskets, i think the aftermarket ones came with it but before finishing bolt ons i left , he just had little too hook up, i am sure he did though i dont think hes that stupid lmao lol .

He obviously has a very poor reaction then. Any good driver would have had you off the line, especially in an AWD. It wouldn't even be a constant with you driving your v6.

To the op: If he has a 2011 WRX, have fun. They run mid 13's in the 1/4. Even if he were to do a COBB tune he could have nice gains. He could easily see a 30 horsepower gain.

You guys act like its hard to rev up a awd car to 4,500rpm and let the clutch go to get 1.7 60 foots.

For a lot of WRX owner it is. lol
I owned a stage 4 WRX and a stage 2 STi. I spent a lot of time with my subie friends at the track. The average WRX owner can't launch his car to save his life.

Most are afraid to rev up to 4500 and drop the clutch so they end up bogging and running low to mid 14s.

But as you stated. If you've got the balls to let the clutch go at 4500 rpms, 1.7 sec
60' times are pretty much guaranteed.
I was pulling 1.6x sec 60' times with just a few basic mods and stock tires.

And to the guys who say the WRX can't handle a high rpm launch. I have a stack of at least 200 timeslips over several years (stock clutch and tranny) with no issues what so ever. The secret is to get a little bit of wheel spin on the launch (no DRs).

8cd03gro · 08-27-2011, 04:29 PM

A proper awd launch is tougher than many might think. Too much clutch and it gets roasted, too little and you bog. Learning how to balance launching rpm, throttle position after launch and clutch use takes some time and most people driving around in sti's, evos, and wrx's would probably cut 2.0+ 60s at the track.
