Kenne Bell makes a screw drive SC for the 5.3L Vortec it is a complete kit and sells for 4K and change check it out here
5.3L Vortec Super Charger. A Motor Trend test showed an increase of 96 RWHP and 136ftlbs of torque. This would mean apx 425 Flywheel HP and 500 ftlbs. not quite a 10:1 power to weight ratio like the stock Vette but very respectfull considering the boost is available at 2K.
I just received a reply (see below) from them on the development of a kit for the SSR looks like it may be a few months away. If they get more e-mail from SSR owners it might help speed up development time.

I Just purchased a new 04 Chevy SSR with a 5.3L Vortec engine. Will your system work on this truck? If so are there any installation differences from the standard "Tahoe" version. Any one else running this on an SSR you can refer me to for a recommendation?
Thanks Rick Giles

We don't have the kit released for the SSR as of right now. We are getting a vehicle in here in a few weeks. Once we get all the measurements and make sure the calibration is done we should have something out in a couple months. We thank you for your interest in Kenne Bell superchargers.
