gonna post this on here since I'm sure Seb and Topgunz are getting sick of trying to help me out with this supercharger/bov flutter. I raised the car up and had my foreman listen for the noise. He said there was air pushing out of the supercharger inlet when the noise was happening. Anyone have any ideas?
