Car is an M6
28" tire

i think the car should go close to 140mpr in the 1/4

It makes peak power at 7,000rpm? If so, 3.73 would be good.

I am not sure where peak power is, on the dyno i stopped at 6500rpm and it was still going north

I was going to try and take it to 7000rpm if it is still making power

If you have good drag suspension and you hook well, I say go with the 3.73's.

If you spin all the way through 3rd, go with some 3.42's.

You need to estimate your trap speed and pick a gear to cross the line a couple of hundred rpm over the peak power. This typically produces the quickest/fastest times.

Running almost mid 130's with 3.73 and 26 inch tire. if I had a 28 would run 3.9.
