While we are dealers for Procharger, Vortech, Whipple, FRPP, & Kenne Bell, I suggest Vortech for centri blowers.
Vortech's have great fitment and are very efficient.
For Twin Screws, I lean towards FRPP/Whipple on GTs.
Either of these units can make 450-550WHP pretty easily.
For GT500s, I like the new Vortech 3.3L twin screw and Kenne Bell 2.8 or 3.6L blowers. (we make 715-780whp with these on close to stock engines)
Shoot me a PM if you would like pricing on any type of forced induction.
