high boost @ low rpm torque monster setup

Yeah, people need to get it out of their heads that's AIRFLOW - not boost - that makes power...

Boost heats up the intake charge.
Anti-lag / misfire stresses out the entire exhaust side from the engine to the turbo to the exhaust system and everything in between.

Boost is quite vague indication of flow against "certain" restriction. So one could say that when you measure certain pressure and temperature at plenum, as long as these two are same, you have same flow on given engine speed. Problem is that engine can pose quite different restriction due to very same device that drives compressor.

My point is that pressure can´t be ignored as there are situations where engine cares about inlet and exhaust pressures, especially their ratio

To the OP, there is something to consider, you can´t change fact that engines natural torque peak is above 5000 RPMs... you know, the feel when the engine really goes hard. If you would run high boost at low RPMs, you will be surge limited to small compressor and consequently choke limited on top end. Powerband wouldn´t be as good as you may think.

You should give yourself some realistic goals, concrete numbers. Maybe there is what you want with rather conventional approach
