Ant..Re Gearbox and my thinking....
I've got a 3.31 Jag rear ratio and am running 295/50/15 rear tyres.
Also got a speed limit on our roads of 100 - 110 Klm....At a tyre diameter of 26.6 inches and a cruising speed of approx 105Klm with a .63 5th gear, the motor would be revving to say approx 1700 RPM....far too low..it would be off the cam. At a .80 5th gear it would rev to 2200 approx..much better.
My want is to have a good highway cruise rather than a high top speed.
If I go with the G-force it would be the helical unit although I have heard excellent reports about the straight cut unit.
Noisy tho.
