That's a pretty significant amount of dust. Yep, the filter is a pretty big restriction. Even with a turbo guard screen, my car made 16.4 psi @7400 rpm. Boost started falling off before redline and I had zero belt slip. I hope someone else chimes in on belt tension. I believe somewhere in this thread there's an explanation. I believe it's based on how much you can twist the belt in the top section between the sc pulley and jackshaft pulley.
