right on, Avoman!
But surely, nowadays, someone could do better than 200 hp from a six liter engine? It's not dificult to get 70hp per liter out of a car engine and still be reliable...
GA piston engines do seem rather behind the times...
Do the advances made in racing aero engines find their way onto production engines?
I would think that there would be significant crossover between the car and aero engine industries...
Am I being a bit naive?
