A G62 turns a 22-10 at that rpm..
I sent Keith one of our race props, a 19-18 carbon..The GT80 methanol racing Zenoahs turn it 9000 on the ground, 11,500 in the air..Keith put it on a 110X on gas, turned 10,500 on the ground...Sure would be interesting to see one in the air...
The Zenoahs clock 188 mph at that rpm...
Unfortunately there is no racing class for a 110X engine[&o]
Hey RTK...Can we borrow your 110X for a test in one of our Formula 1 Kelly airplanes?

200 mph is a distinct possibility
