First off I want to say thanks to all of those who help begineers like me out on this board...but anyways... In lamens terms, what is volumetric effeciency...how can one go above and beyond 100%. I was asking, because I looked at a dyno graph of a higher revving 302 (8,000 rpm) engine and it was seeing numbers in the 108-109% range. It just seems to me that 100% is as far as it would go? Is it a good way of telling performance of an engine?
