Pushing the limit based on what? If BMW puts a rev limiter at 8,400 rpms, do you know what happens at 8,700 rpms? Nothing. BMW could never leave themselves such a small margin for error. Think about it; where does the real damage come from on an over-rev anyway? Valve float. That's not happening on this engine at 8,700.

I think the bearing issue is way over-stated on this forum.
