Just having some more thoughts on the 736NM my engine developed on the Maha....
Checking out the curves below which are (allegedly) taken from the RS Tuning engine dyno there is no big peak rise in torque using the engine dyno whereas on the Maha rolling road which produces a load similar to a WOT road run the engine overboosts like it does on the road - in contrast I think the engine dyno plot is taken by holding the rpm under load at given points. Done this way there is no overboost so the torque is lower as in the diagram below.
The moot point is that the engine dyno diagram shows the numbers the same way Porsche do but the Maha curve represents what actually happens on the road....interesting...
