why do you guy's like a turbo vs a centrif Supcharger?

OK, Back on topic!!!!!!!!!!!!!!!!!!!!! Wooooo!

I'll say this upfront, I have no clue about this stuff. IF I was to go about turbo charging an engine, what company should I deal with in getting a new turbo.[/quote]

I have a pretty good book on the subject which doesnt get too far in with engineer speak. It's written by Corky Bell and is called Maximum Boost. It would help you to read it before entertaining a shop . That way at least you know what thier talking about.
