    Hey all,

    I'm just wondering if those who have done gear swaps can post what RPM's their cars are at and in which gear at the following speeds:

    30 MPH =
    60 MPH =
    70 MPH =
    80 MPH =

    Just want to see what the difference between stock (3.27's and the various upgrades are). Also, does anyone know of a calculator to input these to figure out different gear combo's?

    Thanks!

    One of the best free gear calcs I have run across. You can enter all gear ratios for tranny 1-6, rear end ratio and tire size. You can also define shift point (type in max power) and max revs, displays all gear revs in speed inc of 5 mph.
