any opinions or reports from end users on their experience with JHM Superchargers or any other brand that uses a centrifugal drive supercharger such as a vortec unit?? Any feedback will be appreciated!
Yes JHM has released their Supercharger kit over this past summer! I have not had an opportunity to ride in one of the SC'd cars yet though. You can find people who have purchased and installed the JHM supercharger setup on Euro Addiction or Audi Zine...Most of the S4 guys aren't on the Vortex.
