Default What should I run

This is what I ran at the track with 2.59 gears I think it is pretty damn quick (MPH). Compare it to the one that ran a 12.49 at about the same MPH throughout the run. What should be my next mod to get the E.T down? I know I need to get my 60 foot down its just I have to use the footbrake and E brake and I still almost cross through the beam and that is with shallow staging! Advice? What do yall think I would run with a clean 60' like a 1.6-1.7?

This is my car

The 12.498 is the one I'm comparing to.

Indeed you have 12.6 sec ET potential with that trap speed.

To drop short time and so ET you will need to launch harder:
-higher stall TC,
-DRs or slicks

To hit 12.49 sec you may need to add HP???

Try launching without stalling it up; just hold it on the foot brake with a high idle ( 1K ) and let the convertor flash up when you nail it. Always gave my best 60 ft times

Get some better diff gears and a higher stall convertor ( + DR's )

Heck yeah I can't wait to get a stall in her and gears. I need to get the Vette in the 12's. I will be happy with 12.5's in the old Vette. She surprised the heck out of me. I just bought 3.91 gears and detroit tru trac diff for my GTO hoping it will push her deeper into the 11's ,just gotta relearn the launch. I need to start paying more attention to my vette.
