My supercharger makes a sort of cement mixer kind of noise at tickover. The noise isnt constant and doesnt seem to effect how the car runs. It was doing it when we went to Zandvoort but I only heard it occasionally and from inside the car, it sounded like the rear clam moving with that sound of vibrating fibreglass, and thought that, as the clam had only just been put back on. Its seems to have got worse now slightly.
I can only hear it on tickover but havnet got anyone to rev the car and listen out for it yet.
Below are links to two videos I made to capture the sound (sorry if there a bit big) and a photo.
