Hey everyone, im pretty new on the site, i have a few posts, and i love the wrx's and sti's. I have a few questions for u guys tho.

Last night i raced an STI and since we put together my custom turbo kit at the shop i havent really messed with any STI's untill now. I raced a kid who claimed he was stock (nothing visually noticable, and the exhaust was not any louder then i expected) and we raced from a roll: 40mph-100mph, i put about 1 car on him by the top 3rd before he hit the brakes. My question is what do you think he had done to the car? ive looked around on various websited, cobb vishnu etc, and examined the stock dynos which tend to be around 230-235whp on pump gas. My car is still untuned but pushing somewhere in the 300whp area. What do you guys think just a boost controller?? (just a side note, i had wheelspin all the way through 2nd gear, so i really only hooked up when we hit 3rd) I dont mean to intrude or offend anyone here, im a big member of the VW community and would love to learn more about subaru tuning. :cool: :D

Thank you.
Thank you for coming to this site as an owner of a different make, and being respectful and courteous. Quite refreshing. Please feel free to stay and contribute. Judging by your list of mods, it sounds like we could learn something from you.:)

I'm no STi guru; seems like your average lightly modded STi has maybe an intake, downpipe, and manual boost controller at this point. Not sure what that would put to the ground, but I wouldn't THINK it would be 300whp. Good race!

If he said it was stock then it probably was. I've run dead even or beat cars that should have been much faster than me in my STi. I played around with an Eclipse making about 100hp more than me and I hung right with him.So you can't always go by HP numbers. It reminds me of the Sparco WRX that makes like 400+hp , yet ran slower than a stock STi at the strip.

STi's are making anywhere from 247 whp - 259 whp stock. I've heard of some approaching the 300whp mark with a few basic mods (exhaust, intake, boost controllers)

I've seen some sti's dyno as low as 240. If he said he was stock, he most likely was. You would have heard an intake (like it matters) or exhaust. Only other "non-visual" thing I can think of is a boost controller.

thank you for the welcome, ill get some pics and post them up, but as dumb as it sounds when racing him i couldnt hear anything but my car, i have a tial 38mm external wastegate not routed back into the exhaust, so its very very loud at WOT...i would like to get a run at him with my drag radials on, but by the looks of the kid (that rich boy look) i think he had to have had something (right before i raced him i raced and just beat a friend with a high 400hp 71 camaro small block 350...) so i dont see how it could be true he was BONE stock...my friend at home has a bone stock sti, ill race him and let u guys know whats up. :) with the money ive spent on the GTI i could have had one killer sti :mad:

eh, to be honest, i love gti's when they're heavily modded and done right (as opposed to another sti roaming the streets) You also might be right about him not being stock. I know the type, saying they're stock to save face when they get their ass kicked. Post some pics asap. i wanna see this beast!

The stock Sti has some problems with timing (sometimes) so sometimes it dynos 16whp less than the optimal timing mode. They switch in clycles as the ECU readjusts. But on the optimal setting, with just a tbe the TXS Sti on the TXS dyno put down 293whp i think. An MBC would not add much, unless he's really pushing it. Plus the Sti has pretty good 6th gear for highway races...

I agree. Thank you for coming here and being respectful and courteous to us Subaru members. Most people come here to troll or to start forum dramas. Please feel free to stay here and contribute in our discussions. There are plenty people here that still own SS Camaros', SRT-4's, EVO's, R-32's, etc.

:p :p :p
here are some pics of the setup i was running, the changes i made and how the new setup is right now (the intercooler piping was a weird fit because the new turbo is in a different position then it used to be, so im fabricating new stainless steel intercooler piping)

Nice ride Ed. I also appreciate your manner. You are welcome here any day:cool: What kind of torque are you putting down? That may have something to do with it. The STI is a torque monster with almost no lag. The gearing is also great with the six-speed putting it in it's "sweet spot" almost all the time.

i saw a nice black gti yesterday walkin to class. he had a big fmic, car wasnt too loud either.
if u dont mind me asking, about how much money u put into that? im tryin to decide whether to get an sti/evo or gti
i love the gti's but they are heavy so i think id need a lil more power to get faster

i am thinking he might have had a little something extra cause now that i saw him again his car was a little loud..but anyways i just did some more tuning today with the wideband, and found a vac/boost leak....so now i have a nice power gain...its funny it was so noticable when u had a vac leak before i did the turbo upgrade (the car would stutter and eventually stall, becase the MAF and MAP sensor would be showing very different readings) i was running a maf before, now if my intercooler piping was to fall off, the car wouldnt make a stutter at idle...

btw the torque should be about the same as the hp, when i dyno ill know for sure, the 1.8T is very torque happy as well, thats what causes us to suck off the line...fwd and 300wtq = lookin stoopid from a stop :mad: :(
