At that RPM the prop seems to get into all sorts of things, just what it normally does under these conditions. In addition, the engine is not dynamically balanced yet. The PP is a round hole with 1.5" diameter, beeing effectively about 40mm considering the exit roundings. Opening timing is as in the LeMans engine. I don't think I will ever do max RPM on the ground, since running with a prop is the only power runs I can afford to do.
