Four strokes obviously benefit from superchargers. About two stroke superchargers: While a supercharger won't provide a performance boost on a two stroke by itself for reasons mentioned above concerning exhaust timing, it does allow the use of a much larger carburetor which in and of itself improves performance. Bottom line: yes, with a bigger carb they improve performance but this a totally different reason why they work on four strokes. I'd get into it deeper but dinner is ready!
