implies the same happens at high RPM when VE may exceed 1 on a well designed 
engine.
If high RPM detonation is the problem (which I think Art suspected for his 
engine) you
may be stuffing over 100% of the cylinder volume into the engine.

Seems like it would be a lot harder to detect than the obvious low RPM 
"ping".

This is about the trick with high rpm cams, they move the max Tq to a higher 
rpm.
Moost of the time it will outpreform the Tq of a "everyday" cam. Dan should 
know
what high rpm detonation looks like, but it is hard to hear and destructive.
