So are you suggesting they run a considerably different timing curve? I suppose that would make sense considering how different their cars are not to mention how different their exhausts are. That being the case, dyno numbers on a motor are not going to make a huge amount of difference as both teams are going to be looking for different characteristics in the motor regardless.
So, one makes 805bhp at 18k rpm, but has a more peaky curve in a certain rev range, while the other makes 790bhp at 18k rpm but carries a more broad and useable power curve for one's particular application, but not the other. In the end, they are both looking for different things making dyno figures almost irrelevant. Who knows, maybe Mclaren requests a specific cam timing for their motors which provides a more specific torque curve, and the same could be true for MB or FI.
