How do we know that? I bet the M5/6 guys all say their engines are under rated. |

Air pressure is shown dropped by 3" by the 3rd run which would lead you to believe they are at high elevation (3,000'). They may have corrected for sea level and assumed a non-turbocharged car?

I hear what youre saying but it makes very little sense if everyone is messing with numbers. When I toured the Porsche factory years ago they tested each engine with a 1% HP tolerance. 1% high or low and the engine went back and got rebuilt.

Between the huge delta in just 3 runs, air temperature differences and the correction factor being 'changed'.... these run logs are worthless.
