In a big step forward, SVT has moved to the 2.3-liter Eaton TVS supercharger pullied for 15 pounds of boost. Obviously the blower's outer housing is an SVT-specific casting, but there's more to it than adding logos and laying out the rib pattern. SVT computer modeling showed the short-turn radius on the blower inlet critical to airflow, so this area was enlarged and carefully shaped. In this photo, the blower inlet is the large opening at the right end of the assembly. The intake manifold and associated charge cooler water plumbing below the blower are carryover 5.4 parts.
