ever seen the guts of a rotary engine? Or maybe seen a picture of how one works? the exhaust and intake are never exposed to eachother. Same deal wtih peripheral port.
Have you ever tried to seper charge a peripheral port.
Not presonally, but p-port engine is just a rotary engine with a better induction system.
