Hi all, does anyone know of any software that can calculate wheel speed based on each gear ratio and final drive ratio. Thanks

Hi Tony,

I’ve e-mailed you something, is that the sort of thing you’re after?

cheers

The Eliseparts website used to have a comparison chart for different (Rover) gearboxes to compare against each other and the ratios that are unique to EP. Not sure if it’s still there following the launch of the new site.

I believe standard S1 (close-ratio) gearing is:

First 2.923
Second 1.750
Third 1.307
Fourth 1.033
Fifth 0.848
Reverse 3.000
Final drive 4.200
