in a sense yes smaller piping would allow that...but safest bet is 2.5"

on 12 psi of boost. your mass flow rate at the mid range is 14.49 lb/hr. at top end your flow rate is 28.97 lb/hr. your pressure ratio is 1.82PR. i am looking at different compressor maps now as to what would fit your needs the best

You may also want to learn the difference between a roots type super charger and the way turbos make psi

superchargers basically stacks air ontop of itself in the intake manifold because the blower moves more air per cycle than the engine can injest thus the excess air creates positive pressure in the intake manifold

turbos on the other hand are different, they suck air in and to put it in simple terms throw air at a wall (compressor housing) and it compresses itself and then is pushed out through the turbine outlet

too small, you would be overspinning it and taking it out of its efficiency range

i just read the compressor maps dude. with your corrected flow rates, your gonna be in the "sweet spot" right before mid range and at high end your going to be overspinning it. you want your mid range lb/hr to be just after the surge line on the compressor map
