I hate to say this, but it seems you may not fully understand what you are talking about. I would advise that you study up on internal combustion engine theory, and forced induction (both turbo and super, and the differences) and how nitrous works.
I would love to help explain/clarify some of these things for you, but it would take a loooooong time to type it all, and I prolly couldn't explain it nearly as well as others.
fyi, there is a fantastic book on turbocharging out there called "Maximum Boost" by Corky Bell. It provides an excellent resource on turbocharging and the practical applications of turbo theory.
