I am still making 370nm torque at 7000rpm though and torque only starts nosing over at 6800rpm. It is still making 360nm at 7800 and power is still climbing at 8000rpm.
390Nm at 8200 was our best but i was right on the edge of knock - that is 335Kw atw (449hp).
We have dialled it back quite a lot on safety grounds as I want the engine to last. so 370nm at 8000 is where we settled which is 310Kw or 415hp all atw
Assuming 15% parasitic losses in the driver train (might be 12%), that is an estimated 485hp at the crank.
