> that makes me doubtful about longevity of the engine if the shock wave touches the metal.

Sure. But what about the common reciprocating engine style. There's a lot of mechanical strain with the pistons being yanked back-and-forth 1000s of times/second not to mention the energy lost in counteracting momentum.

considering the upvote to your comment, there is at least another HN reader who thinks that there are 60K+ rpm reciprocating engines and who don't know what detonation sensor, octane number or cavitation are about... Hope you know your Python better :)

Heh, good catch. Should have said 1000s of times per minute.

60k is 3x the RPM of an F1 motor.
