Want American, How about a big Holset Off a Cummins out of a junk yard? (although I thinkthey are Brit?)

Superchargers, they take 50-100HP to run them depending on boost level, they are belt and gear driven so they make noise, there are many moving parts in a gear driven supercharger, and they all produce drag, its not very EZ to manipulate boost levels unless you change pulley sizes, Belt drive supercharger have gear change lag, ie when you drop RPM's, the boost level goes down proportionally to the RPM drop. A Turbo has more of a buffer (stored pressure) especially in automatic cars, less lag (not to be confused to its own shortfall, turbo lag, which can actually be beneficial in wheel spin control) When you are not using them, they are still running. Throw a belt, dent your hood...

Whats a paxton cost?
