Default Gearing
Anthony,

I dont know about those maths, all I know is 50mph at 7000 in first gear is to low and will just be useless and fry up, and 75mph at 7000 is to higher in first gear - so I guess somewhere in the middle and I have come up with 58mph @ 7000 on a 3.27 with 25.6" diameter rubber.

Other things to consider are cruising speed with 3.27 gearing is 3000 rpm = 70mph, quite low, but in NZ the roads are crap, and I am building the car to get off its arse and motor to 160mph @ 6800rpm - that should do it!
