What are you asking?

4th gear is 1:1

I don't think the dyno needs to know the gearing info.

4th gear is 1:1 so it will give "correct" numbers

Did you forget the existence of the rear differential?

Huh? So you're saying I should divide the RWHP numbers

correct-5th is usually 1:1 in a 6sd

Ugh you guys! Multiply by the rear diff

You get no torque multiplication from the tire. (n/m)

He is correct about turbos spooling quicker in higher gears

Chip(GMS Racing)
12:32:25 08/10/04
Yes I have nothing to say about the spooling
