I deal and talk to BMW al day and i decided to call my vendor and my dealers about this issue. I even E-mailed my BMW contacts in Germany they all say they messure at the Engine.

So I hope this clarifies things...and the HP rating for the M5 is 395 hp. Although some top 400hp. Freak M5's. the M3 is 333hp to the engine. And with BMW's subtract 18 to 19 percent from the engine HP and you will get an estimate of wheel HP. if you want to be more exact its 18.9523%.

I hope this helps!

Directly from the source, that's good enough for me.

You guys can speculate all you want. Until I see a Contour running low 13's, I won't believe it.

Edit: I just realized the original question was from a roll. Doesn't matter, the only time one is racing from a roll is on the street, not the strip, so from a roll shouldn't matter in the slightest.
