I wonder if you could chop a turbocharger into a turbo-shaft? I like the idea of diverting the corrosive exhaust gases.

OK, Porsche use pumped air cooling! Their fan can have 5 to 11 blades depending on your backpressure needs.

Someone showed a subwoofer (I think it was a commercial product) that used a constant-speed variable-pitch propeller. It could produce notes as low as 50hz by reversing the pitch in a cycle. For your compressor/vacuum pump.
