Not really, not like a turbo or anything. It's just a stationary "fan" with an ace bandage and hose clamp over that rubber boot. (see album). The air going over the bike goes straight into that boot though. The idea is to force the air to spin in one direction to prevent pulsing, and pack more air into the carb.
Google intake tornado for cars, it does the same thing.
If you want to see how it works, cut the bottom off a 2 Liter bottle. Cap and fill the bottle. Let it drain (glug glub glub). Do the same thing with the little fan laying in the bottom. (Shoooooooop -empty)
You can get the fan blade off with a big flat blade screwdriver by gently prying and turning from under the center part, and prying the magnet out. They are free in the trash at computer stores.
