Look at the charts from RRI. They have max hp at the wheels @7821 rpm. The max power at the crank could be achieved at a higher rpm, but the transmission losses go up with engine speed, so if the crank gains are very small between 7821 and 8300, the tranmission losses could trump them, and you see what these charts tell us at the wheels.
