I have read the above Wiki guide for gearing. I do have a question, my car has a 1.83 final drive ratio which is very different of what most of the cars in the marketplace are using (mostly 1.9 to 2.0). Should I gear the motor to get less RPM and more torque to offset the rather high FDR of my car? I feel the car lacking punch with the current gearing I'm using for a 21.5 motor on a big track (leisure hours). Using a final drive of 3.7.
