Let me see if I can get this right:

Supercharger
------------
Technique: Uses power from the engine directly to run a fan to improve air
flow into the engine.
Advantages: Doesn't create an increase in back-pressure, which reduces HP.
Also, power is evenly distributed across the RPM band because of active
powering.
Disadvantages: Requires power from the engine, so you don't get a 100%
increase in power.

Turbo
-----
Technique: Uses exhaust pressure to run a fan to improve air flow into the
engine.
Advantages: Runs on passive power, so you don't lose any power from the engine.
Disadvantages: Restricts free air flow out of the engine, increasing
back-pressure, and reducing overall power from the engine. Provides power
only once you start getting air flow in the engine, so it doesn't give you
much low end power on the rpm band.

Corrections, anyone?
