Cruise Settings P337

[JeffAxel]

Frank,
I flew my P337 at 2450 RPM, 30" MP and 24gph total, which was 50 LOP and roughly 65% power. I would see 185KTAS in the high teens with those settings with all CHTs less than 380 with the cowl flaps closed. My plane was air conditioned and had Riley intercoolers and GAMI injectors. FWIW, I fly my current P210 at 2300 RPM, 30" MP and 14.5 GPH 50 LOP which is also ~65% power and see 175-180KTAS at the same altitudes.
