My friend and I finally had the opportunity to run both our cars yesterday from a roll on the highway. My 05 sti is completely stock while his 95 dodge stealth TT has had some work done to it. He has a cai, a complete custom 3" turboback exhaust with no cats and an engine management running more boost. I wanted to go from a dig but he only wanted to go from a roll. We decided to go from 40 and the first run I started in 2nd and he pulled about a half car lenght on me fairly soon and pretty much stayed there until about 120. The second time we did another start from 40 and this time I started in 3rd and stayed dead even through 3rd and 4th gears all the way until I had to shift into 5th gear where he pulled a little and again we stayed even until 120. I guess his extra horsepower, but extra weight kind of evened out compared to my car. I told him to wait until I get the turboback and ecu and it won't be pretty. He laughed it off saying it won't make that big of a difference on my car. Oh, how little he knows.
