Some of you may know, but I got my *** kicked a month ago by a stock 05 sti with 60k miles. I am getting my 3" racing beat exhaust in 2-3 weeks. and i am getting my old style hks gcc soon that i bought brand new from ebay for $48.00(GOOD FIND HUH?). I will be tuning for 12psi and hoping for 240-260rwhp. So do you think I can take this stock sti out? This was the first sti I ever raced and i dont know anyone with a sti, so i have little experience with em. If I lose then, I will tune for 14psi. If I still lose, I will go BNR Stage 1 Turbo to keep the turbo looking stock to pigs with 720cc injectors. This is the furthest i will go for now, because I need to find me a good miata or trueno for dd still.

well....tuning for 12psi on a stock turbo? OK, fine and dandy - could be possible to hold 12 psi steadily enough for a "tune"

14 psi? mmmmm not so much. You might get spikes of 14 psi, but not enough to consder that you're seady running boost level. At least in my experience with the HT-18

As far as you beating an STI (Im assuming we're talking 1/4 mile here) I've seen BONE stock 02's and 03's at cayuga run in the high 12's. One guy ran on C-12 one night and pulled a 12.3 second pass.

And most of them weren't driving worth ****.

You *may* beat him, but its notvery likely, you'll need more powah!!

maybe ill get him from a roll then. but they really run 12s. c & D says 13.5 for 05. thats amazing though. well, the car has 60k on it too, so hopefully it isnt in its best shape.

you should be able to beat him if its stock

12.9's and .8 mostly....the one dude a few weeks back was running mid 13's but it was his first time to the track.

It will mre than likely come down to driving, but if oyu're both evenly paired then he *might* take you out again.

Don't take this as me bashing anything either, I hate to see 7's lose....Im just giving you some fore-warning of what I've seen at the track.

I say you lose.

I'm guessing you would dyno around 230rwhp max with 12psi. I woudln't recoomend going near 14psi unless you hasve a wideband to tune with because you said your still looking for a DD. Don't go toying with your only ride at those boost levels.

A stock S5 is around 180rwhp.
10psi may bump that to around 200ish but in the end..... It's all BS and guessing because each engine runs a bit differently and depending on the health can vary in power.

From a dig and the guy being AWD he could get an easy jump on you if he knows how to launch.

i think hes tryin to beat him on the straight. my opinion, no matter if ur car is 240 - 260 hp, his car is 4 wheel drive. now, if ur goin touge/canyon runs, ull probibly beat him if u drive better than him. if ur fc a s4 u should port ur wastegate on ur turbo and get a upgraded ecu if u want to raise ur hp widout ur engine ****** up.

Send him my way, I will hand him his *** for ya!

mtek7

you will lose , he got more power in a stock engine , and is not worth it to sacrify your engine without fuel mods to run safe. get a set of 1600 secondaries a walbro 225, stand alone , better safe than a rebuild .

Carzy Driver

you need a FMIC aswell. it doesn't take long for the top mount to get bad heatsoak. spray paint the FMIC black so no cops can see it. that plus 720 secondaries and RTek 1.7

Well, I already have the HKS PFC F-con with HKS GCC and Walbro Fuel Pump. Also I am gonna use my friends Wideband so I can tune it. Don't worry about me tuning it. I forgot where I read it, but stock injectors can support up to around 250hp, but I'm considering on 720cc secondaries to be even more safe. RETed even said it was ok to boost 14psi, and erikseven is boosting 13 on stock turbo. I've been boosting 10psi all this time of 6 months and 8-9k miles and have been racing a lot and punched it way over 50+ times to show just about all my friends who ask, but i do drive normal when not racing. And my compression is still the same. I have no problem in doing the rebuild myself if it goes and plan to rebuild it by next summer anyways. dont worry i got parts already for a rebuild like rotors and such, and dont worry about me not having a car, i can always get a non-used car from my family. I just want my own dd car of my choosing. I'm fully aware of modifications. And RETed's website is a good source. I really just need your opinions of the outcome or what I may need to win.

Back to the topic: How much does Sti put down to the wheels? And is that on an average people put down 12.8 or is it just the best drivers? This is the first sportscar for the sti owner so I doubt he is one of the best and his car has 60k so his engine is used as well. I don't care if I beat him by a fender, I just want to win. But as long as I can give him a good run, im fine with it.

btw, i would get rtek 2.0, because it sounds bad *** for the price but i have an s5. so too bad for me. and standalone I wouldn't get until I upgrade to a bigger turbo. theres plenty of people i know have pretty good tunes with just fuel computers like hks gcc, safc, with mildly modified engines.

550's on the stock ECU run at about 57% duty cycle. With your controller cranked to the MAX you will be pushing almot 80% duty and at that level, you can support about 240bhp.

BHP

so in reality you'll be putting 210 or so to the wheels. The STI is 300bhp. So he's still go you there.

Im still doubtful that you can ACTUALLY run 14psi on our stock turbo consistently. And either way, anything past about 12 you're just boiling you I/C and blowing hot, wasteful air into the engine...you're better off (and just as fast) running 12.

Yep, thats about the max reliable amount of boost you can run on your stock turbo...12 is really the cap. Thats not surprising or any kind of huge feat to do that for 6 months orlonger. I ran my 87 with its stock turbo for close to 30,000kms doing 10psi.

As I said, Ive seen a guy on his first trip to the track doing mid 13's, so no. A driver who is very familiar with his subbie will probably crackthe 13 mark or come close to it though.

But its still 300bhp....pretty much gaurntee that. How many km's on your motor now?

Then run him. What was your best run in your car? If its anywhere near the bottom of 14 seconds then you should have a close race.

your best bet is from a roll
i own a 2003 wrx with a cobb stage 2.5 which is about 330bhp (and yes it'll eat a stock sti)
and an 87 tII with at the time 550/890's, retek 1.7, 3" full exhaust and about 12psi of boost.
racing them against each other my subie would kill the 7 from a stop, but at a 25-30mph roll the 7 would jump ahead and keep pulling

According to RETed, its ok to run 14psi. But I know a lot of people dont recommend it. I was thinking about it, but not sure myself. Most likely I would run just 12 psi and run 14psi with the BNR Hybrid Stage 1 Turbo, and of course I would get a FMIC then. I know 80% is close to the 85% max safe level, so I've been considering on getting 720cc secondaries, and decided to get them a while back as you can see in my sig it is something I've planned.

Its a jdm engine. so i dont know, but this engine is really good for for a jdm engine. it was pretty clean and everything was in good shape when i picked it up unlike my first motor(bad motor), and some of my friends motors. I get 95psi in the front and rear with 3 even bounces in each rotor. I know 95 isnt the best, but its pretty good for a jdm.

I haven't ran my current setup at the track yet, but on the street I have yet to lose to s2000 from a dig to 120mph, mustang GT from a 70-120mph, ls-vtec integra from dig to 110, or 2 mildly modified eclipse gst from a roll 20-100 and 50-100. the s2000 was a close race and the mustang gt was killed 2-3 cars. I also went neck and neck with a stock srt-4 from 40-100.

I am just hoping to give him a good run at least from a dig. And if I can take him from a roll, that would be koo.

hopefully i can put down more hp than this guy who has the same shape motor as me but its an s4 motor and he has a 2.5" side exit exhaust with 10psi, while i will have a 3" straight through doing 12psi on a s5 motor.

Remember when you get a BNR upgrade that PSI means nothing when comparing turbos. It's CFM.

10psi on a stock unit could make 200rwhp while 10psi on a hybrid could be anythgin from 300-500 depending on the turbo.

T2 FC3S

I was able to race a wrx and evo in the freeway and i pulled on them pretty good. I ran a 300+ wrx with a front mount and pulled by a couple cars. I think the evo I ran was stock, but still. Im still running on a stock intercooler at 10lbs, haltech E8, street ported engine, 890cc sec, supra fuel pump, RB downpipe with apex catback, LS1 coils, etc..........not too many mods and the car runs pretty decent. Dont have an idea on how much rwhp I have.

Eternal_Gamer

iTrader: (10)

yes i know. i am planning to get the bnr stage 1 and some have dyno'd 290-310 rwhp at 14-15psi. so thats what imma do and it will still look stock in other's eyes and especially from the pigz.

Koo, if you can take em than i should be able to give em a good run whether i lose or win. id be somewhat happy if i could take em from a roll. i just dont wanna get slaughtered in 3rd gear like the 1st match which was a roll 20-100mph.

Race the guy and see how you make out, losing isn't a bad thing - if no one ever lost a race there would be no need to go faster.

dont worry, it will be at night in clear traffic road in the countryside. I live in the countryside. so its all good. and dont worry, i aint no sore loser with excuses, every time i lose, it gives me more determination to be faster. oh yea, i also have some good michellin tires($145 per tire new) i got for $20 barely used with like 90-95% tread because i work at american tire co.

I know your **** is fast. its not fair if we are comparing it with yours though.

Well, thanks for all the replies. i am looking foward to this race whether I lose or win from dig or roll. I will most likely have it videotaped and in the kills section and this will happen in a month or so. i cant wait.

adrock3217

From a roll...you have a VERY good chance of winning. STi's only put like 250 to the wheels, they lose a LOT thru that AWD system. With 12psi, 3" intake and exhaust, good tuning with a wideband..you should put down around 240rwhp. Less weight, and no top end hinderance(AWD), you should DEMOLISH him from 50+ mph.
