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.
