As for the converter, I paid attention to trap RPM the best I could the last time I was at the track. According to Wallace's slip calculator, I'm 18%-20%. The question is: how low can you expect it to be in a combo like this only running 3.55s in the 1/8? Hell, I can cross the stripe around 7,200-7,300 in 2nd. Figured I'd try that once.lol Would a single digit slip number be too tight in this case and bog the motor down? Those will be my questions for PTC. Nice numbers! I'm curious, how much did your car slow down when you crossed the line in 2nd gear? I have a 500" pump gas duster street car with a 9.5" fairly tight converter and 3.23 gears. I've been kinda wanting to drive to the track and run a low 11 second pass with the 3.23 gears. Motor makes plenty of torque.

As for when I crossed in second, I can't find a couple splips and that's one of em. I believe it was a low 6.60 @ 107.6 or so??? Wow that's impressive crossing in 2nd. Have you ran it with a steeper gear? I'm just curious how much you think it slowed it down.

Have you ran it with a steeper gear? I'm just curious how much you think it slowed it down. It probably did not slow him down much. I was running 5.14 gears that was probably not low enough for my combo and broke them and changed to 3.50 gears and only lost 5 hundredths in the 1/8. 6.34 @ 108 to 6.39 @ 109 crossing the finish line in 2nd gear.

Always loved the car and it makes good power. To bad you guys don't have a 1/4 mile track to race at anymore. Awesome ride!
