I am a little confused as to how the same amount of PSI makes more power depending on what is creating that pressure. I always knew that bigger turbos had to work less because they flow more, therefore they can force MORE air into the same space more easily. Thats why a bigger turbo will have a much easier time making 40psi than a tiny one which would have to spin itself into kingdom come to generate 40psi.

However, that hardly explains anything. So please someone explain to me how "boost isnt boost".
