To me at least, it appears that all surmised numbers could very well be the nearly whole truth



Of course, max torque would be converted from NM so here are other possible torque values:

540NM = 398.28lb-ft
535NM = 394.59lb-ft
530NM = 390.90lb-ft
520NM = 383.53lb-ft

But with playing the above and the RPM one can easily hit the desired hp output

Nicely done
