After fitting my axle, I am running a 3.73 axle ratio and 245/45/17 tyres, this gives me 38 mph at 2000 rpm.
This made me think - what speed are you guys doing per 2000 rpm.
Could you post it up here , I think it would be interesting, with rear tyre sizes
Use Dave's fantastic calculator :-

55mph @ 2000rpm with the overdrive in, 43mph if it's out.

That makes my 38 mph seem pretty low, may be some higher rear tyres ?
245/45/17 = 25.68 inches

Johnny those are small diameter tyres. 3.73 should fly, though
