Only paperwork stopping you adjusting the governor of your Maule to get the extra 200rpm and extra horsepower - prop limitations aside.
It's know too long for me to reliably know but think it was 2400 rpm max. The prop was big, so think tip velocity might have been a consideration in the total set up. Miss the aeroplane, miss the strip and the fun it afforded us.
