After reading the description I see why P-Porting is good for NA
aircraft can it be combined with turbocharging?

Absolutely. Anything you can do to streamline the intake
system makes the turbo charger work better. It also cuts
the fuel burn per HP generated.

Drag racers get 800 to 900 HP out of a turbo two rotor.
