		FYI, auch von die Englishes Dynoday Thema auf MINI2.com
From Andy @ Ross-Tech.com
Interesting thread, but there is no way to accurately determine crank horsepower on a chassis dyno. The amount of power being absorbed by the driveline and dyno rollers during a coastdown is not the same as the amount of power absorbed by the driveline during acceleration. No self-respecting dyno shop in the US would quote crank power figures, so it puzzles me why the Europeans do it.
I'd stick with the whp figures in order to have a glimpse of reality.
