No, not really such a thing as a supercharger on a quad, there's no external pulleys or anything to drive the supercharger. You can buy turbo kits for a select few quads but the 350's aren't one of them, only the bigger machines like the Raptor 700, DS650, stuff like that. Even if they did make one, I'd be willing to bet you wouldn't buy it though, the kits usually run around $3,500, almost as much as the 350 costs brand new.
