Not sure where this thread belongs.


I have 26" slicks at hand and would rather not switch to 28".

Now, going by others setups similar to mine.NA I should be around 118-120, with a 3.31 rear gear and mt82 4th at 1.32 I am still good with the GT mani that would put me at 6600-6800 according to the Wallace racing calculator below.

Now the dilemma, I plan on hitting it with nitrous at the track from time to time,will deff see more NA runs though.

I would need to rev it to 7200-7400 through the traps depending on shot size. Do you think it would cost me a bunch of time going that far past the manifold efficiency?
