I think this is the mistake...assuming it's entirely due to the BOV. Yes, the BOV can alter the sound, change the RPMs, etc., but I don't think you can address the entire problem from one end. The shop owner who installed my kit races, has lots of experience with superchargers, and, as I mentioned, installs many centrifugal kits on Mustangs. (He has a Viper GTS that makes 3500hp, among his cars.) He believes the issue is mostly with the intake side.
He explained it this way: Picture your s/c compressing 15 cubic feet of air into your manifold, but the engine is cruising, only drawing 5 cubic feet. That extra 10 cubic feet is going to squeeze out the front of the supercharger, and will be modulated by the spinning of the compressor. If you're always drawing against a slight vacuum, you'll moderate that "overpressure," and muffle the sound through a filter.
I hope we can nail down a good fix in this thread.
