I'm in an arguement with some other car nuts, about whether volumetric effeciency can exceed 100%. I think that if you're getting a number over 100%, you miscalculated something or left a variable out. They think that a value over 100% is completely normal especially in turbocharged and supercharged engines. If they are right and I am wrong, what the hells the point of measuring it's effeciency if it can go above 100%? Would this avoid the whole conservation of energy thing haha?
