    boost noises

    when i come off WOT i can actually hear the whine of the vacum. Is this natural or do i have a leak in the gauge? I hope not because it sounds cool!

    the sound last exactly the time it takes for the needle to drop on the gauge. To me this seems normal, but i'd like some advice for peace of mind.

    I think what you are hearing is compressor surge when you chop the throttle. It's a pretty common noise with the Green Chargers and Gen II impellers.

    sry to get off topic, but do the metal washers make a different sound then ceramic... since i had my supercharger rebuilt it sounds different, is that just me or is that really happening.

    Yes, they do make a unique sound.
