hey man, does the word "humble" mean anything to you? Don't get all cocky just cause you got a good time. You don't know the DA where he ran 13.5, and you don't know what mods he has. If you have more mods, then you SHOULD be faster. If his DA was higher then you SHOULD be faster.
i think 13.8-13.9 at the most with an auto. you need to focus on coming off the line harder. stickier tires, and a torque conv. will easily put you into the 13.3-13.6 range. also maybe think about getting a 4.10 with an auto instead of the 3.73
You guys have no faith in the 4r70w. I happen to own a 2001 GT auto and i ran 13.83 with just Mac Lt's, o/r h, and a K&N. With the addition of magnapacks, c&L upper intake plenum, accufab 75mm TB, aluminum driveshaft, 3.73's,diablo sport predator, nitto 315 drag radials should put me in low 13's easily. We will see when the time comes and the track opens up at route 66 in joliet, IL. Before I go to the track in the spring I will take a poll of what people think I will run with my mods just to test peoples knowledge.
