Supercharging a motor?
Very interested in the concept of supercharging RC motors. I am very familiar with how they function on a normal vehicle, however, just was wondering if it had similar function on RC motors?
Can any RC motor be supercharged?
the reason im brining this up is becuase I recently bought a megatech dark thunder and noticed that RB innovations had a supercharger kit for it! does this actually function to the point where it is noticable?...cool concept either way..

"...similar function on RC motors"
Nope. RC engines are 2 stroke. Car engines are 4 stroke.
"Can any RC motor be supercharged?"
Yep, something like a 4 stroke aircraft engine (Saito or O.S. etc.) would be the best bet, though weight and drag on the engine would defeat the purpose, and in reality make things go slower.
I'm sure people will come on here and say there's no way you can have forced induction on a 2 stroke engine- they are wrong.
Snow mobiles are an example of it being done on a 2 stroke. Though they are 'reed motors'.
Another argument is that the inlet and exhaust ports are open at the same time. Doesn't mean diddly squat when your talking about an engine revving over 20K. By the time the intake air is about to go out the exhaust, the piston will block it off at those revs and a tuned pipe has a supercharging effect for pressure waves pushing back at the exhaust port stopping excessive/wasteful gasses getting out.
Forced induction would work if you could get enough volume pumped in there. But it will NEVER happen with an RBinnovations kit.
Don't bother supercharging, buy a proper tuned exhaust. Will be the best bang for buck you can possibly do.
