Here's what you quoted above from the owner of the shop that built your car:

"It’s the shop owner’s belief that it occurs because the supercharger is creating more pressure than the engine requires when cruising, and the pressure is cavitating out the compressor fan blades out the opening of the intake. He’s calling it a type of “compressor surge.” I’ve got the “hair net” filter on over the opening, and he said that if you could rig up a GoPro camera to look at the filter, you’d see it vibrating in and out when cruising. He feels that the solution would be to put a pancake H&N-type filter on the intake, so that the supercharger is always pulling against a slight vacuum. Or, if there might be an S-curved charge pipe that could fit a larger filter behind the bumper. Just something to create a small amount of vacuum on the intake."

The owner of the shop that built my car told me the exact same thing and suggested exactly what your shop owner suggested. I'll never know now since I blew my motor before we got to that point. And as much fun as I had experimenting with superchargers, I accomplished pretty much what I wanted with my build(s), I'm going with tt's now.
