I have the transmission mounted on a Corvette LS 1 engine. The transmission was engineered to handle 600hp. The LS 1 has 350hp at 5600 rpm. It has 350 ft-lbs torque at 4200 rpm (approx #s). For takeoff, the engine will develop 350 hp at 5600 rpm and the 84 inch Ivo-prop will be turning at 2700 rpm. For cruise, the engine will be run at 4200 rpm and the prop will be turning at 2700 rpm. (ABSOLUTE RED LINES)

 

I did the ground testing with a Subaru 2.2 L engine on my Q-200. This was the test stand. I did taxi tests in both gears and the performance was as expected. The thrust instrument I used for static tests was not calibrated and very crude. It showed slightly less than what could be expected for the 2.2L. I will in the future run tests on a 3.3L Subaru, but that will be after getting the Bearhawk flying and tested completely.
