I'm not going to tell anybody to go out and buy a supercharger for their redcat or baja, but I can tell you that the physics says a supercharger can work on a two stroke engine.
The people who disagree will always say the same thing. The intake and exhaust ports are open at the same time so you can't build and pressure in the combustion chamber..
But what people fail to realize is that it takes time for air to move. Also, a supercharger will be pushing pre-compressed air into the crank case. Once the more dense air/fuel mixture enters the combustion chamber, it will have to push the exhaust gases out of the exhaust port to fill the combustion chamber. That keeps the the pressure up.. a simple way to put it is squeezing air against air.. combine that with the sonic blow back of a tuned pipe, and the result will be a more dense air/fuel mixture being trapped and burned in the combustion chamber.
Of course some of that pressure will bleed off through the exhaust port, but not all of it.
Common sense says that pressure will be equal everywhere inside a container. But that is only static pressure. The air directly in front of your fan in the living room is more dense than the air across the room, even though there is no exhaust valve keeping it confined in front of your fan.
Pressure moves in waves. Waves that happen to travel at speeds slow enough that a piston cycling 8,000 to 20,000 times per minute can trap.
I'm not saying it would be easy or even feasible to supercharge a 30cc single piston engine, but it is certainly possible.
