There have been a couple of guys from a different forum have the kit installed..one lost his motor due to a faulty fuel controller, the other one was having oil leak issues (that have been corrected) with the blower itself. I honestly don't think the 5.7 is built for a blower due to the high ring lands..steve said:Is the GS Supercharger kit reliable enough for a daily driver? Are there any other supercharger kits out there? I have Paxton, Magnusun, and Vortech all within 20 minutes of me. Has anyone contacted these companies for a kit?
