I suspect (but am not certain) that BHPc refers to the brake horsepower reading from the dyno, corrected to standard conditions of pressure altitude and temperature. The power produced will vary with pressure altitude and temperature, which are pretty much outside the control of the guys in the dyno. If you want to be able to draw any conclusions from the dyno results, you need to correct them to standard conditions.Tbone said:Received my test cell data from superior on my I0-360-B1AD2 and was curious what those terms mean in reference to the engine data?

In the Superior manual it shows SFC for peak EGT and for a specified number of degrees (50 or 75 - don't recall which) ROP :.43 and .50 respectively. They say full rich SFC is >.55. Keeping in mind they were testing a completely new engine, that would suggest they were running rich. I'd call them for a better explanation of the test cell sheet.Tbone said:My figures were... Intake air temp 86f, baro 29.9, rpm 2643, MAP 29.26. The BHPc is showing 160.44 and the BSFC is 0.6102. Not sure what that means but out to the side it shows in the comments section (Acceptance Test: BHPcn=180.15, BSFCn=0.5763. Are those the corrected numbers for horsepower and fuel consumption ratios? Just curious to know....![]()
