    Off the top of my head

    1st = 3.58:1
    2nd = 2.02:1
    3rd = 1.35:1
    4th = 0.98:1
    5th = 0.79:0
    Final drive 3.63:1

    reverse = 3.31:1

    Whats the max speed in each gear of the Coupe Turbo, I assume it's same as 888? (Sorry to hijack topic)

    Cheers for that.

    Anyone know the ratio of the lower final drive Courtenays offer?

    Accordingto the courtenay website it's 4.17 (Final Drive Ratio)

    However the F23 in the 2.2 has a FDR of 3.95:1 (also 5th is 0.81:1, with the other gears being the same)

    Scott - mph per 1000rpm

    1st = 5.4
    2nd = 9.6
    3rd = 14.4
    4th = 19.9
    5th = 24.6 (21.7 for the 2.2)

    Cheers Geoff, you have no idea how much help that actually is

    EDS Stage one ups the rev limit to 7200rpm ... so with that drive ratio is the Coupe Turbo capable (With enough bhp & Torque) of hitting 177mph? or have I worked that out wrong lol

    I have done calculations with these figures. It seems with the torque spread I have, the lower ratio would in fact slow me down over a quarter mile and 0-60mph.
