How is that 30% power gain quantified? Nitrous oxide is used in gasoline engines to add oxygen to the fire which with extra fuel, makes more power. In model engines, nitromethane serves the same exact purpose. Using higher nitro will do the same thing - and probably more efficiently. Forced induction has been used on 2-stroke snowmobile engines with success, but most often those engines have some form of an exhaust valve. In a 2-stroke glow engine, the crankcase is what needs to be pressurized above atmospheric pressure to do any good, however there have been no proven methods of using forced induction in such a small glow engine with repeatable results and some sort of scientific proof it actually works. Dyno results will prove it, but anyone who has a glow engine dyno probably knows it's a bit of a snake in the grass to make anyone believe it actually works. Ad hype means nothing. I have an RB Innovations supercharger and it really is a joke both in how it's made and how it functions.
