mr0077,
Re: adjusting the rear end ratio to suit engines minimum cruising speed.
The engine will be used up to 7000rpm on the circuit, when under pressure in a 5 lap sprint race, all other street use will generally be way down 3-4000 range, with the regular 6000 - 6500 blow out through the gears.
I would prefer the engine to be getting on the camshaft at around 2800 - 3000 for cruising, but I guess thats what you have a transmission for! I doubt whether a 7000 rev engine would start running nice at 2500?
