How do you work out the revs at 100km/h.
i've got the final drive ratio and the 6th gear ratio. Cheers |

If you've got the final drive ratio, and the 6th gear, you should hopefully have the rest of the car... look at the tacho - lol.
Seriosuly, there was a thread not too long ago that had an excel sheet, where you could put in tyre specs, gear ratios, and diff ratios, and work it out.
