    Supercharger Clutch - function - How does it work?

    I just picked up an SVHO and had a question that I seached for unsuccessfully.

    I have a pretty good understanding of mechanics and like to understand how things work - the supercharger clutch function has me baffled.

    I assume the clutch isn't engaged until a certain RPM is reached for either ease of starting or low speed or low load fuel economy - but I haven't been able to find info on the why and when it is engaged/disengaged.

    On the SHO/SVHO, why is there a clutch?
    When/what cause the clutch to engage/release?

    TIA, Chuck

    Look up sprag bearing theory. The clutch is just that...a sprag bearing.

    Thanks! So if I undestand the function of the clutch correctly the SC spins up faster than the engine RPM and as the engine RPM drops it allows the SC to freewheel.
