Vortech S-Trim upgrade?

What the hell is it?
S-Trim Upgrade-Includes high efficiency, curved blade S-Trim impeller, high speed precision balanced to racing specifications, new S-Trim compressor housing, replacement of all bearings and seals, new select fit impeller spacer and nut, new compressor retainers, a detailed inspection of all supercharger components, all balanced and assembly labor. What good does this do?

I think this is the HD upgrade (for cogs)

Sorry Ian, I believe that DOES NOT include the HD bearings.

Sounds like the upgrade from an a-trim to an s-trim.

I agree with Rdrunnr
