No ifs and buts: Superchargers do NOT work with ported 2-strokes. At all, period. You need a valved 2-stroke for that, and even then the effect is limited.
Sure, you can "hyperventilate" a twostroke, but then all you are doing is wasting a lot of fresh fuel straight into the exhaust, and the power increase only comes from less spent gasses remaining in the cylinder. That however, is not supercharging.
Turbochargers CAN work with both ported as well as valved 2-strokes. But turbochargers do not scale down very well, and in the size of our toy engines, zero chance that such will work: Simply because the power required to produce any significant boost at the volume flow required, is more than the energy availlable in the exhaust gasses.
It cannot be done in the sizes of engines as used in this hobby, and any vendor saying it can, is selling snake oil and hens teeth. Period!
Keep in mind: ANY engine manufacturer would immediately start producing turbochargers or superchargers if such a thing actually worked. ANY competition rider would use one if it would give him an edge over the competition.
Reality is: Only ONE manufacturer (and not exactly the silliest one at that, OS from japan) did, and built only a few hundred of those supercharged engines before they called it a day because the gains were not worthwhile. That was a 1,2 Cu.In fourstroke with a proper Rootes Blower on its back.
