stupid question time...
~id like to know more on this subject...most of my knowlage about this is based on assumption!
superchargers are belt driven and brake down in to several different types.
twin screw superchagers (also called positive displacement superchargers)..like the magnachargers, eaton, kenne bell.....use the engines belt to spin them, very good for low end tq because of no spool time.
centrifical superchargers.....basically just the compressor half of the turbo but instead of an exhaust housing they have a pully....also create strain on the motor to turn.
i know i did not cover everything this is just what i know......
