In my earlier post I didn't take in to account that you could go to full rated RPM at 10,000 feet to produce more HP but I still find it hard to believe that you can produce 90% power at 10,000 feet , even at max RPM, with only 65% MP. Just a gut feel here. I'll not let scientific fact get in the way. :-) Larry Flesner
