Piston Speed

richd · 10-10-2002, 11:55 AM

I've heard that optimal piston speed is around 50-60 ft/sec. My question is this:

Is piston speed measured at the point where the piston is travelling at its highest speed (mid-stroke, when rod base is at extreme right/left) or is it averaged over the entire stroke?

Just curious. Thanks!

Piston speed, measured in feet per minute, is measured with the following formula:

Stroke (in inches) times rpm, divided by 6.

Take care,
