Out of curiosity, what is the cruising RPM on the 599? At say 70 or 75 mph..
Easy to calculate. Top speed at 205 mph = 8250 rpm, 75/205 x 8250 = 3018 rpm 5th and 6th are both overdrive with 5th 0.94:1 and 6th 0.76:1. It is a nice long-legged beast, with lower gearing like a drag racer. If you want to know what it is in 5th, multiply by 94/76. Taz Terry Phillips
