With = nothing else to do, I thought that I would take a few measurements. Condition LOP Lo ROP Hi --------- -------- --------- 11,000 IA 2,350RPM 2,700 RPM 13,000 DA 19.3"MP 19.8"MP 30.08 "Hg 6.0 GPH 8.6 GPH 12=B0C temp 139 kts IAS 152 kts IAS 35=B0F dewpt? 168 kts TAS 183 kts TAS 1,670 lbs For a 43% increase in fuel, a 9% increase in airspeed doesn't sound like = much. However, 183 kts airspeed at 13,000 ft density altitude, no matter = how you do it, is great. The LOP reading at .435 BSFC comes out to HP =3D 36 * 6 * .435 =3D 94.0 = HP or 94.0 / 160 =3D 59% power.
