275mm X 35 aspect ratio X 19 inch rim: 791.029 revolutions per mile (80.098in Circumference)
(275/35R19)

So, now calculate how many RPMS your axle is at with the motor spinning 7500RPM.

Final gear = 3.69
Sixth gear = 0.79

Math: 7500 / 0.79 / 3.69 = ~ 2572.811

Now figure out how many miles per minute you're going:

2572.811 / 791.029 = ~ 3.253

Now multiply by 60 to make 1 hour: ~ 195.18MPH.

OK... Now we have our max speed in 6th if you got enough power to push it there!


EDIT: For those that don't know, the "~" means "approximate".
