Supercharger for 05 Mustang GT

The SEMA show that was on Speedworld
said Ford was going to offer a "twin screw" blower that should add 100 hp. Also MRT had a Paxton SC on their Stang.
No prices mentioned but I think they should be about the same as earlier SC's
 
Ford Racing (FRPP) has one
Paxton has one in the works as does vortech
Kenne bell is also working on one.

You can finds small bits of info on each site about them.

No one knows the results yet though.
