Superchargers

[zed211]

When you say superchargers do you guys mean only the roots type, or will you also be able to use centrifugal superchargers as well?

[Daffyflyer]

Roots, Twin Screw and Centrifugal, all the common ones.

As for Roots chargers, will there be both the old, nearly straight, twin lobe blower and the newer 3 or 4 lobe hi-helix (160deg) style?

The ones you normally see on muscle cars and such, (6-71,8-71,etc) are the old type.

The charger on the ZR-1 Corvette is of the newer style. (Eaton hgv 2300)
Cadillac uses the Eaton hgv 1900 for the CTS 6.2.
Audi uses the Eaton hgv 1350 for the S4 3.0 TFSI.
