As with the rest of the "supercharger" this is purely an advertising gimmick designed to suck money out of impressionable newbies. This thing straight out doesn't work. Read the car engine forum here in RCU and you'll find pages and pages about this thing.
I am with downunder, i will say the "super charger" in 2 stroke model engine will not work.
Because the transferport and exhaustport are open ,and there are atmosferic pressure in the cylinder, hi pressured air/fuel mix are blowing out of exhaustport. The "supercharger" are not blowing the air/fuel pressure in the cylinder with pressure since the induction valve in crankshaft are allready closed.
You are throwing money out of window for the 2 stroke engine with "super charger" who are not more powerful than normal 2 stroke engine.
Better to run 2 stroke engine with tuned pipe.
