Supercharger sounding like "shhhhhhhhhhhh"...

Like the title says, during startup in the morning, my supercharger sounds like a high pitched "shhhhhhhhhhhhhhh". I have checked the supercharger fluid level and I added some last week. The sound didn't go away. Anyone got any ideas? The reason I am posting this is because during my search, no one's complaint "exactly" sounded like mine. Any help would be greatly appreciated!

Next time you start it up cold, Have someone else start it for you. Take a small section of hose to listen for the noise. Its most likely your power stering pump or a idler pully gone bad. Belts have a way of making some strange noises to.
