I did a climb to 17,500 yesterday to check out my oxygen system after working on the regulator (yes, with a fingertip blood sat checker), I didn't specifically watch the time-to-climb but I was up and back down again in 36 minutes. My home strip is 2700' and I climbed at 1000/min until 10,000', then climbed at 95 knots after that, I was still climbing at 500/min when the autopilot leveled at 17,500.
IO360, Whirlwind prop. |
those are good numbers.

With the O-360 I typically cruise it at 50 to 55% power which works out to 150 to 155 knots and 7 GPH. Up in the teens, it can burn a much lower fuel numbers while keeping the speed up there. |

Calculated by my spreadsheet, to memory of MP =20 Hg = 54% power. And... I don't drive as fast as I used to. Maybe there's a correlation. |

159 knots @ 5.2 GPH. Not bad at all! I love the -9 wing! |

In any case, I get asked all the time what kind of efficiency I get and I normally respond with "I flight plan 160 knots true at 8 gph." More than once I've been called a liar straight to my face. I just shrug my shoulders and smile, it's not my job to make believers out of the spam-canners. |
Thanks
Thanks for the data; great stuff
