Providing the ports are timed and angled ideally, boosting crankcase pressure (trapped compression) will not increase the effective combustion compression ratio, but rather can improve scavenging because of the increased crankcase pressure. The true and only way to boost the compression ratio with forced induction would be timed pressure to the combustion chamber after the exhaust port is closed in a ported 2-stroke engine. In a valved 2-stroke, obviously the exhaust valve just needs to be closed. So to reiterate - supercharging or turbocharging a ported engine is pretty fruitless because boosting cylinder pressure isn’t possible. RB Innovations sells snake oil, and they know it. A lot of people are pretty dumb and buy their hype.
