Bravo-Ovation-Acclaim

[Bentonck]

...just to add on to the Acclaim...mine has had 4 of the 6 cylinders overhauled and it's at 850 hours at this point.  I bought it at 650 hours a year ago with 3 cylinders already done...I'm normally running it at 29"MP/2400RPM/15-16GPH fuel flow LOP, but I can't be sure how it was operated before I bought it.  At this setting in the mid to high teens (I gave up going above 18k because wearing an oxygen mask just isn't fun to me) it trues out high 180s at always-higher-than-ISA temps here in Brazil.  If I get any wind I'm over 200kts and if not I lope along at 15gph getting twin engine speeds.

I'm not even worried about the top-end overhauls, it just costs 5gph more to get another 8-10 knots which seems like a huge waste, especially where AvGas costs $7-8 a gallon.
