Agree to that. Our projections on the turbo 20B are much higher than that.

  Ed;



  Seems like your numbers are about 100 hp - or maybe one rotor - too low.

  Doug, at 15 gph at 6000 rpm, Mark would be making approx 165 HP, perhaps a bit more, using a very conservative  BSFC of 0.55.  If you assume a bit better BSFC of 0.49 it would be around 183 HP.

  Mark:



  Great story...thanks for posting it!  At 6,000 rpm and 15 gph, how many HP do you think you're developing?



  Also, have you by chance flown side by side with another Lycoming powered ES for comparison purposes?  If so what did you learn?



  We're going to have a couple of "burger burns" at our airport ((2OK2) just east of Tinker AFB) this Spring / Summer, so maybe you'll feel like going on a short cross country up this way and show our little EAA chapter what a three rotor looks and sounds like?!    Blue Skies
