  1. First thing I would do would be to remove the serpentine belt and start the engine to make sure it isn’t coming from the alt, tensioner, etc.

    If the noise vanishes at this point, spin the pulleys and listen for a slight noise, it won’t be as loud but definitely a noise.

    Still a Noise.

    Then remove the Supercharger belt and run the engine and see if the noise is still there or it goes away. If the noise is still there, then it is most likely the counter balance shaft bearings going out.

    If the noise is gone, then your Supercharger bearings are going out.
