Nah, missing the point.
Dropping off 50Nm in the last 1500rpm isn't going to "save" the engine, given the piston speeds at those res anyway.
If you want safety you want to reduce peak torque in the mid rang and how savagely it makes it, that's what destroys the bottom ends and boxes in them. Ask Evo owners.
That's all I'm saying - I also do not know exactly what the torque limits of a stock bottom are, but I'd be thinking 450Nm rear wheel would have to be nudging it and I'd cringing a little each time I got up it waiting for the either the rod bolts or the ring lands to fail - but I am a sensitive Susan who always assumes the worst.
Anyway, I hope it lasts many roll racing events and wins all the kebabs and Brazilian honeys hearts.
