    Unhappy whining engine

    My engine is making a loud whining noise I think it could be the supercharger but i'm not sure. As I said it is very very loud does anybody know what it might be or have any suggestions???????

    this on a 90 SC with a 5spd.

    Just when you floor it or all the time? If all the time, check power steering fluid level and check to make sure the vacuum hose hasn't fallen off the bypass valve actuator (on back of supercharger) or that the bypass valve isn't stuck closed.

    When the hose is off the bypass valve stays closed and the linkage fits very close to the back of the supercharger and can sometimes get stuck.

    Any of these will cause a constant whining noise.
