I have created an excel file that calculates the speed in MPH for each gear on the 63-65 M20 & all M21 as the engine increases in RPM from idle to redline and above. The user only needs to inputs the rear gear ratio and tire diameter in inches.
for the 66-74 m-20 change the ratios to 2.52, 1.88 & 1.46. (M-22 is the same as the M21)
The gear ratios can be easly changed for the other transmissions.
If you wish a copy of the excel file please send me an e-mail.
