Who said Maximum Boost is laughable?
Suggesting that two entirely different turbos, all things being equal, will always produce the same power at any given boost pressure is what's laughable.

It looks like this thread got derailed but Ill give my 
When it comes to power what your really interested in is air density. Your engine always displaces the same volume per 2 revolutions (1.6 or 1.8L). So your always taking in the same volume throughout the RPM range. What changes is air density which allows for more oxygen molecules per volume of air which in turn allows more fuel and more power. Pressure and temperature are the two things that affect air density the most. Hence the turbo charges and intercoolers.
