    New R&D supercharger upgrades

    R&D C5 (no longer need to send in your housing for machine work)
    15-16 psi at 8400-8500 RPM.
    http://www.4-tecperformance.com/inde...oducts_id=1062



    The C20X makes 18 psi at 8500-8700 RPM and 20 psi at 9000 RPM.
    This upgrade requires you to send in your supercharger's front housing for machining.

    Very close to that because I know someone running the E1 at 9k RPMs.

    Hitman; do you know the difference between a fairy tale, and a Southern fairy tale??

    A fairy tale starts off with; Once upon a time......(I know a guy....)
    A Southern fairy tale starts off with; Y'all ain't gonna believe this sh#tt.......

    So, how close to 20 psi is your "friend" running??
    My "friend" is running 20 psi, with data logs to match.........

    Get sum!!!!
