Over the years many of our customers have asked us to calculate an engine's RPM at various driving speeds (MPH). Sometimes they've changed a transmission, a rear axle ratio, or even tire size. All of these things will effect what an engine's rpm will be at a given vehicle speed. In order to make this information more readily available and convenient for our customers to find, we have developed an on-line RPM calculator that will accurately provide this information. It's also set up so that you can easily input and make changes to any of these parameters and get immediate results.
