In an honest opinion from someone who has owned an awful lot of forced induction cars, the concept of super or turbo charged two strokes it prectically impossible. You cannot pressurize something without a sealed combustion chamber, end of story. All the air you are feeding in is just going right out the exhaust port because air will take the path of least resistence. A 4 stroke engine, yeah, it could work but for proper fuel managment, there is no room for a rising rate fuel pressure regulator on an RC vehicle. Use the search as was stated before. I myself have typed more than one very lengthy explainations of why no power adder will or can work. Its simply not possible. Use that 180 bucks to buy a better engine, you will be much happier.
