TIMBLE ITS NOT S/F THE COMBUSTION WAVE DOES NOT TRAVEL AT THE SPEED OF SOUND.
this has nothing to do with the idea that the piston is travelling faster than the speed of sound.
I had to think about that one and push the numbers, but yeah, mach 1.2 or more is not unusual.... these things are moving much faster than I ever thought!
