I will try to put it in readable english as I understand it ok?

1. Superchargers and Blowers are two words used to describe the same thing.
2. The supercharger is usually run off of engine power (usually by a belt or similar device- sometimes gears) and changes the engine intake from a vacum to a pressurized area. There are a multitude of different types of superchargers so I wont even go into it. But the most common are the roots (twin rotor) and a centrifical (like the compressor side of the turbo).
3. The Turbo is actually called a turbo-supercharger.
4. The turbo usually runs off of the spent engine gasses (exhaust) and uses these gasses to turn a turbine. This turbine is connected by a shaft to a compressor wheel. as with the supercharger it pressurizes the intake charge to add more air to the sylinders as the intake valve opens.
5. As an internal combustion engine is only an airpump - it would zstand to reason that a pressuriozed system would work better than an atmospheric one would right? (try to run a oneumatic drill by hooking up to the air and pulling the trigger- then to a pressurized air line and do the same- obviousl result but a good comparison for a forced induction engine)
