HSTuners - View Single Post - No replacement for displacement is a crock!

Modded vs. Stock- Why does it matter? Wouldn't those mods be replacement for displacement? Wouldn't ANYTHING that increases output other than displacement be a replacement? And if the Enzo motor is the same size as yours, does that mean yours is just as fast? By the no replacement for displacement theory, the two motors should perform IDENTICALLY because they are the same size.

By no replacement for displacement, every 1.8L motor would have the same output, PERIOD. Every 400ci motor would have the same output, PERIOD. Every motor would have the same specific output, PERIOD. All three of these are false.

There seems to be some confusion about ram air. Ram air is creating boost by traveling at speeds such that there is a compression effect in the charge air. Ram air does not START until speeds of about Mach .5 (half the speed of sound!) are reached. And if you're reaching half the speed of sound in the 1320, I don't think you really need boost.
