Understanding Piston Speed in High-Performance Engines
WEBJan 24, 2015 · Maximum Piston Speed. You can get a very close approximation of maximum piston speed (ignoring rod center-to-center length and rod angularity) with the following formula. Multiply the stroke by pi and divide by 12 to get feet per revolution. Then multiply by the maximum engine speed to get the maximum feet per minute.
