So, the statement that "Yeah, well, I can boost the bigger engine and make even more power." In fact further verifies that boost is a functional replacement for added displacement.

If forced induction is 'virtually' adding displacement by making the engine behave as though it is much bigger than it actually is ... then have you actually replaced displacement as the ultimate delineator for engine performance?
