A turboprop aircraft uses a gas turbine. It sounds like a jet but it has a propeller driven via a gearbox off the turbine shaft.
The engine in that 928 would be driving through a reduction gearbox then most likely on to the automatic transmission.
What I don't knowis how you would control speed of the car. I wouldn't have thought that you throttle back the engine so I imagine that the gas turbine runs at a constant speed and there is some way to control how much 'drive' you put out into the transmission?

Thanks - that's sort of what I was thinking, but the big exhaust pipe out the hood was confusing. I haven't looked up the engine but I assume it's for the APU or something. Too bad he couldn't route the exhaust somewhere other than a big hole in the hood but I guess at ground level it might get dangerous. Maybe vent it out through several outlets would be an option, I don't know.
This is about the most work I've seen somebody do to get out of timing belt changes!
