Default Gear Ratio Calculator

Here’s a gear ratio calculator for doing the math on gear ratios. Normally you need to have a estimate what the MPH and maximum RPM would be. Then you can use the gear ratio calculator on the M/W site to play with the ratios and tire diameters. This calculator has transmission ratios included but most drag race applicants would look at the last transmission ratio that would be 1to1, unless you have an overdrive transmission Its fun to play with and is the modern version of the “Dream Wheel” that Isky Cams and M/W produced before the computer age.
