I have to disagree. Numbers are numbers.......thats it.
Power is made UNDER the curve! Yea the STI may be capable of 331whp but how long and when?! The last 500 rpms?!
We all know about the 'Dyno Queens' but the strip is where it matters. If you can't hook and put that power down when you need it then your not going to be fast.
I'm not a fan of FI for that entire reason. So many import guys slap a turbo on their inline four and get it to push 300 whp but run 14's in the quarter mile.

Man STi's sucks. 330awhp with an upgraded turbo? Pathetic. I made 346awhp on my 05 EVO with full exhaust, intake a pair of cams.

No it makes plenty of power under the curve because a 20G isnt a big turbo. Its the BIG BIG TURBO 4cylinders that dont make good power under the curve. STi's are infamous for that since they redline at 7000 and with some turbo upgrades don't get full boost until 5000rpm.
When I had my EVO (with stock turbo setup) I raced an STi with 420awhp on pump gas with a GT35R turbo. I had 378whp at the time and I walked it easily all because his power under the curve was junk.

There is a lot more to racing than just WHP and weight.
The fact that the STi had a turbo upgrade mean its going to have much more turbo lag than stock. My friend's stock STi has turbo lag pretty bad, expecially from a roll. Each time you shift, you get that dead spot in the powerband before the turbo spools, and then it pulls. So with a larger turbo, that turbo lag is going to be much worse.
Not only that, but STI's also have much shorter gears. Meaning in the time an M6 F-body goes through 2 gears, an STI has already gone though 3. Time spent shifting is time you're not accelerating, and each time you let off the gas, you have to spool the turbo back up. Takes about half a second for a stock STi to spool between shifts, with a larger turbo obviously its going to be longer.
Wheel HP doesn't mean shit if you can't use it effectively. As for weight, a stock LS1 F-body weighs within about 100lbs of an STI.

What I wanna know is what gears you are running. You threw it in second going 55?? In my M6 that would be around 5500 rpm, enough to make me cringe and my car hate me for a few days. Also it would only be in second for what, two seconds?

I assume I have the stock 3.42s. 55 in second is just about redline for me.

yes it has stock 3.42 gears and 2nd gear will take you close to 72mph on stock gears. haha i went and talked to the sti guy yesterday, he says he quit so noone won the race. but if you ask if he was in front or behind when he quit he wont answer

Blue02Z, how far into the redline are you running it at that speed? IDK why my M6 would be so different unless you're running it into the redline quite a bit.
