Did a 20mph roll run with my friends STi. wasn't planned. just he hit it and i followed suit. for a lil back round see... http://www.srtforums.com/forums/showthread.php?t=29011
stock vs stock i could of reached out and open his rear door from my door off a 20mph roll. sence then i've added 30hp and 30tq (dyno provin) and lost .7 seconds in my .25mile time . the only thing the sti has changed was just a cat back exhaust. what bothered me is that when we ran this time it was the exact same result as the time before when we were both stock. upsetting to me to say the least. i didn't gain a inch till around 90 were i gained maybe a half car and we shut down at 100. no way the catback gained 30hp and tq, so wtf happened? i'm still upset. my af's were a solid 11:1 and i was boosting a healthy 19psi to 15 at redline. car felt strong. the only differnce from last time to now was he was on winter tires as apose to the stockers. the weather was simaler (sp) as well as the weight. owell, better luck next time.
i ran a 13.5@105 and he ran a 12.9@106 (stock)
