It sounds 100% freaking amazing-- like everything I love in an engine.

When it cools down we'll do some 8600 pulls to see if it can make any more power. Last night we had a engine build celebration and the builders still think there's more to be had, but we'll see. I'm happy as is, it feels infinitely more engaging than the F80 CS as you can imagine.

That's why I was asking about the redline-- it didn't look like your engine had leveled off yet necessarily, and it seemed like there should still be RPM on the table.
... Have you considered fooling with the intake trumpet length at all? If you're going to rev it another 8500rpm, and can't cam it further, you might be able to shift the curve up/right with some shorter runners. Almost certainly you're outside of the design spec of the stock runners at this point
