Re: piston power! [re: ToxicCarbon] 

Yes at 5000 rpm the crank would be spinning at 83.3 rps (revolutions per second) but you made an error with the valves opening at 166.6 times per second. The intake valve(s) will only open during the intake stroke, and likewise the exhaust valve(s) will only open on the exhaust stroke. You have 4 strokes, intake, compression, power, and exhaust. Each individual stroke will be revolution of the crankshaft. So each valve will open every 2 rotations of the crankshaft or 41.65 rps not 166.6.
