At the wheels?

Or is this dyno calibrated to do the math of "calculate back to crank" and spits out this CRANK HP value?

It's ok.

All the stupid people on the Net will be suckered into believing this carp - and befor eong BMW fan-boys everywhere will be posting everywhere that the E60 M5 is producing 640bhp.

Ideally, every dyno pull would be done under identical atmospheric conditions. This is seldom the case, so a power correction factor (CF) is applied to a measured power reading to compensate for changes in barometric pressure, temperature, and humidity. The power CF helps make it possible to compare dyno runs performed at different locations and under different atmospheric conditions, but it is not 100% accurate. The most common correction factors used are Standard, SAE (Society of Automotive Engineers), and DIN (Deutsche Industrie Norm). Less common are EEC, JIS, and Uncorrected. SAE uses less favorable atmospheric conditions than Standard or DIN, and it is the most frequently used for rear wheel testing. Lower correction factors also tend to be more accurate. It is important to remember however that a CF is only intended to compensate for small atmospheric differences and doesn’t correct for other factors, such as engine and oil temperatures.
DINCor = DIN Correction = 1.039
Getrie = ??? The Correction Factor for this is 1.1 @ 2028rpm
P-Verl = Power Dissipation (Verlustleistung)
P-Rad = Power at Wheel (Leistung am Rad)

It is 99% sure that the 390.2KW is @ crank..........

No - it 1000000000000% sure.

Plain and simple.

Stock BMW E60 M5's do NOT produce 530hp at the rear wheels..
