A supercharger is a way of pumping more air into an engine in the belief that it gives it more power. It may work on some types of engines, but not nitro engines.
Yeah, I've seen some videos of "supercharged" RCs but the guys don't tell you much about what's going on or how much tuning it takes to keep it running. These videos from Squirrelrod dispute those supercharger claims.

Tells you what it does, how it's supposed to work, why it won't work on a nitro engine. A good detailed explanation.

In part 2 you get several views of the RC and see it in action including chasing the dog in the backyard -- before adding the supercharger. (Could have done without the music... let's hear the roar of the engine!). Then watch as the supercharger is installed and see how it performs (or not).
He tried to run the nitro engine as rich as possible (to keep it cool) and still nuked the insides. As Squirrelrod says towards the end of the second video, he paid roughly $150 for the supercharger and now would have to pay another $150 or so to get a new engine.
Tell me, do you think the idea of a supercharger is worth the money, worth trying? It didn't work for Squirrelrod, but I'm sure someone out there will want to prove it can work. Not me. I've got a lot less expensive ways to ruin a good nitro engine.
