    Fizzle/Tial Bov question

    Does the tial BOV that comes with the fizzle have the correct spring in it ? Mine seems to stay open more than I would think.

    Your friend is probably running a 10 psi spring (designed for Turbocharger instead of supercharger)

    My Tial is the same, stays open until I give the throttle a good quick squeeze. I was running my ski on the hose and watching the Tial, it stayed open as I slowly increased the RPMs to 6000 and didn't even close then. When running on the lake the power feels fine and I can hear the Tial working so it must be inherent to the setup we run on supercharged skis.

    All BOV work on concept of vacuum so it will stay open until right vacuum achieved for the set up of spring.

    The ski is not under load when it's on the hose

    I thought it was not recommended to rev that high when on the hose.
