Tire and Gear Size Question
Tire and Gear Size Question Im thinking about swapping my 3.73 with a 4:10 Here is the deal though. I run a 200-4R and a 28/10.5W tire and Im going for a ~140 maybe a little more or a TINY bit less. Will I be able to run a 4.10 with the nitrous and be good as far as RPMs / Mph go. I shift at 6500 on the nitrous in first and 2nd. I shift at 7000-7100 on motor. So that is the RPM info.
What do you all think.

4.10 with a 28" tire @ 140mph= ~7000rpm (assuming 1:1 gear ratio)
EDIT: Just tried it on another online calculator, and 6900 rpm is 140mph, 7000 is 142. I assume that tire growth is not acounted for in these online calculators, though.

I think it depends on converter slippage.
I have a T400 + 28x10.5 and have decided to gear down to a 3.70 and remove my 4.10's from the 9". I am shooting for 140-145mph with the blower.

I have a Yank 3600 thats REALLY tight for nitrous that is going in the car. This weekend my first hit at it with only a 150 shot is going through a motor/nitrous converter. Its not to loose, but its not to tight. I still have 3.73s so we will see how it goes as far as RPMs goes.
