What is an RPM Probably a stupid question, but what is an RPM
I know it is a revolutions per minute, but what exactly is revolving 4000, 5000, 6000 etc per minute.
I want to get an idea of how hard my car is working.
Sorry for the newb question, but I always wondered that

RPM is revoloutions per minute.
It counts how many times the crankshaft makes one rotation. just remember your car redlines in the high 6000 area where as a car in Nascar red lines at high 9000 area and Bikes and F1 cars spin all the way up to 15,000 rpms. Now THAT is amazing!!!

another piece of useless trivia - in a 4 cycle gasoline engine each spark plug fires half as many times per minute as the crankshaft is rotating (engine running @ 1500 RPM = plugs firing 750 times per minute)
Also, I think the camshaft turns at half the speed of the crankshaft (right??)
