I'm a Machinist and I think I just found a new hobby. Thanks for the post op!

Combustion engines produce 200+ psi, just from air compression alone. Add fuel and spark and that compression rises 15x. Or ~3,000 psi of pressure, an air engine can never compare to the power unleashed by burning shit. And this is just atmospheric compression, add forced induction and HOLY shit, add detonation and the pressure is high enough to launch pistons through the cylinder head.

Still a cool video.

*Math was off, didn't account for efficiency of the engine, more like ~1,300 psi cylinder pressure.
