Similarly the torque starts to drop off sharply at 5500 rpm. Total torque drops by about 25% between 5500 rpm and 6500 rpm. This leads me to believe that the turbo is maxed out. Maybe it indicates that BMW just tuned it that way, but I think its more likely that the Turbo just can't keep up above 5500 rpm.

Reported in the light of the BMW M2 MotoGP Safety Car news:
"The outstanding performance of the production engines can actually be surpassed, thanks to the BMW M Performance Power Kit." (

No details known yet about that MPPK for the M2, but it may push the official hp figure close to, or even beyond, the 400hp barrier. So BMW must have left enough room for some extra oomph.
