Here is a clue...is the S65 forced induction? I never said a crossplane crank NA motor can't rev high. You would have to be pretty stupid to not know that.
The turbo V8 in MP4-12C would not rev to 8,500 if it wasn't a flat plane crank. Lower rotating mass allowing higher maximum revs.
I have seen some cool LS V8 flat plane crank conversions revving over 9,000 rpms. Flat plane cranks are also the reason why exotics sound the way they do.
