ok so go ahead and start the "flame fest" but im wondering as to what exactly the difference is between say, a twin screw, whipple, roots, and positive displacement superchargers.
(maybe a link to another site if its just too much to type.)
sorry for the noob question but i've never got into forced induction and have always been a fan of N/A.
Edit: on second thought maybe im looking for more Pros and Cons than anything else.
