Alrite so im running 22 psi's trifecta tuned with hahn catless dp,dejon sri and a synapse hot pipe. my friend on an sti has about 21 psi's but he says they go down to 19 after a lil while idk, he has a custom tune,intake and a turboback exhaust and hes hitting around 320 I belive. We raced from a 65 roll and he claims that he was in 5th the whole time at 3,200 RPMs and I was about 4,800 rpms,while I started in 3rd. I had a small jump on him like by half a car and we ended up staying with eachother till like 105 and he slowly edged away after that. What am I doing wrong,I shiftet very quick almost the the same as NLS except I have a BOV so I cant. What are sti's supposed to be pushing at 21 psi's and cobalts at 22psi's. BTW I have a canned tune from vince,the traditional one. I was embarassed after the race since I was supposed to be taking him on the highway cuz I have fwd. Im confused. Should I raise my psi's to 26?

 

I seriously doubt the guy stayed in 5th , those are tractor gears and 5 gear is useless on the interstate. Go back to stock BOV and get your NLS back. other than that , the race sounds about right.

 

My other friend was there with him to confirm it. I cant really go back to the stocker bpv since the plastic hot pipe is restrictive.

 

a) No way was he in fifth
b) PSI is not the only determinant of power, with a good tune it is possible to make more power on 22 psi than 26 psi

 

Who says you can't NLS with a BOV?

 

See I wouldnt believe him either if he was alone but he was with my other friend. His excuse was that its hard for him to start off in 4th cuz he can shift. Maybe it was because he had a custom tune and a had the canned one,hmm?

Can you? Thats pretty much power shifting then isnt it? Technically I have my BPV and BOV working at the same time since I never got my delete plate in.

 

Why not? I NLS'd when I had my hks setup w/ delete plate and it worked perfectly fine.

 

Lol I was scared to NLS with the BOV im gonna deff. try to do that next time

 

awd is better than fwd

 

But on top end it takes alot more power to turn an AWD system than a fwd system. If the two cars are the same horse power..... the FWD car should walk away.

 

from a roll ? AWD has something called LINK-AGE say it with me now ...

 

If he really was in 5th you should have walked him hard. Try starting off from a dig in third gear that would be the same as being in 5th from a 65 roll.

 

Yeah , i didn't even bother with the "5th" gear statement ....... If the STI was in 5th gear ..... it's gotta be a 700hp car with the best clutch known to man.

 

He says in fifth he was at 3k rpms I started off in 3rd at about 4,300

 

That is not really what we are disputing. I think either your car is way underpowered or his is making way more than 320 awhp. You should have killed him!!! Heck If I used 5th gear to race I think a 1990 civic would kill me from a 65 roll. Even though the STI is geared lower than our cars he should have been in 3rd at 65 mph.

 

Well what is considered underpowered. See im pushing 22 psi's and I dont know what whp im at. My car does spin tires in 2nd tho from a 40 roll.

 

Depends. Dyno with your stock tune and then with the other tune. The gans shoudbe huge 50-60 whp and 70+ wrtq. Either way you should have killed him.

 

ok if he has 320 awhp it doesnt matter weather ur front wheel drive or not, he is still putting down 320 hp to the wheels, after the loss because of awd. So that race went about right cause u both have about the same hp going to the wheels. But id think he was heavier so dont know about that one. Plus his motor is bigger than urs so he is making more hp per psi.

 

let vince know your exact mods and bump it up to 25. im running 25 with no problem. and keep no lift ****. the stock intake is the best for trifecta tune (so ive heard) unless you have the new one that vince and Clear Image was working on. you shouldve beat him man. hes lying about something lol

 

He wasnt in 5th. No way...no how. I believe your buddy and the otehr buddy are just trying to make your Cobalier look bad. Hes at 320 AWHP with a 3350+ lb car in 5th gear with a passenger. You are probably at 310-320 FWHP with a 2950+ car in 3rd gear (possibly without a passenger). Plus you should build boost faster than him...twin scroll vs single scroll.

Seriously this race shouldnt have even been close.

And BTW - Another NC member...sweet.

 

Yeah the guy was screweing with you to make his car look better.

You should slowly walk him.

 

How do u figure it shouldnt have been close? First off the cobalt is 2975lbs and with him in it at lest 3120 or so pounds which is not much diff from the other car, and the wrx is at 320awhp, it will be faster than the cobalt with fwhp. the only issure here is a few hundrad pounds of waight. And the non twin scroll turbo wont spool that much slower, its not like he has 10 seconds of lag or nothing. I dont believe he was in fifth though, that a pile of crap, he pick up slow as crap, there he is lying. The race should have goon exactly the way it did. who won in the end was total driver skills.

 

AWD from a roll isnt going to benefit. And its not really a FEW hundred lbs. its like 4000lbs. Why do you think the stock CSS blows away a stock CSRT, even though they are rated at 25 more HP? Weight...and bad aerodynamic design, but weight is WAY more important here. I am not going to do the whole HP to Weight crap, because A. Its kinda gay, and B. Its kinda gay. And I agree with the twin scroll to single scroll comparison, but I was just pointing out ANOTHER small benefit the CSS has. In regards to it was won by "driver skills", what driving skill is involved when your car is already in 5th gear?

Again I repeat, the car WAS NOT in 5th gear. Now if the STI was in third, I could see the outcome of the race being exactly this.

To the OP...when you raced him, did you hear his RPM drop, or his BOV? I would think you would have heard 1 of these things, because he had to have changed gears.

 

i agree, the sti wasnt in 5th gear, he would have gotten his ass kicked bad if he would have been. awd will benifit from a roll if the cobalt wass spinning when he shifted or when he put it to the floor, i know iv done it in third.
