Do I know anything? Well considering I design, build, and race cars I think I've got a bit of knowledge about drivetrains. Hell, its simple math anyways. Just google the calculations.
Speed in each gear is a defined value and can only be changed by adjusting the following: individual gear ratios, final drive, and tire size.
THATS IT
I dont give a shit how you drive, for a stock S2K you CAN NOT do more than 80 mph in 2nd gear. Get Michael Schumacher for all I care, even he can't drive an S2K above 80.
