The compressed air is then sprayed with fuel and an electric spark lights the mixture. $500.00. You can see below that a Corvair head easily has 3x the air passage area as a VW head does, with much more passage area and thinner fins. The upright versions are mostly used in trikes, light twins and replica aircraft that require a narrow engine package.

I like the GPASC method better, as the plug wires stay out of the oil bath by exiting between the pushrod tubes to the bottom of the engine. Lot of aerospace experience, but I could not find any actual engine or specifications. The inside of the aircraft engine is subject to its own atmospheric climate that can be very hazardous to the internal steel parts it contains. Aircraft engines can be used by different forms of aircraft to improve operational efficiency and be safer and more reliable.
