    Riva S3 boost Issue

    Installed a boost gauge on my rxt, and I'm only seeing about 8.5 psi from my Riva S3. Also it seems slow to charge up. When hitting the throttle it take 1-2 seconds to build up full boost, is this normal or is it usually almost instantly?

    Just trying to figure out if I need a rebuild or if I have a boost leak.

    Thanks!
    Nick

    Have you checked the supercharger slip? How many hours on the clutch? Is this the old Riva S3 127 wheel or the newer S3 a.k.a. just a plain X charger?

    This is an older Riva S3. Bought it used, seller said it has about 60 hours. I guess the first step is to check the slip, can I do this while it's installed?

    Yes. You will have to lock the engine. I believe there is a how-to for checking the slip while installed. I don't have the exact link for you, sorry.
