Some of the earlier aftermarket pulleys were apt to come apart.
With what little there is to go on, I don't think you have a supercharger failure, I would look toward the SC clutch and pulley.
I work in the city, if you are close by I could look at it after work.
I would have to agree...something engaging clutch, or a pulley failure...doubt it is the s/c....
