I'd read up on turbos first before you go and say "its faster." Obviously you don;t know much about forced induction.
PM buckshot....right now he has a 3 liter pushing 400 WHP.
On a supercharger....im sure theres a logical reason why he wen t super instead of turbo....do research before you judge.
Given the Vortech kit is not the most reliable out there....but some people are happy with it.
Check out these boards and read all the forced induction posts.....there is a lot of info just floating around that can really inform you.
