I am currently trying to determine what RPM the blower is turning with the 9PSI pulley to see how close I am to the 52K upper limit. That 928 motorsports impeller also looks promising but would cost a bit more than a pulley swap.

There is no way for you to know how close your are to the limit of the unit without having cog pulleys.In order to find out how fast you are spinning the blower you have to put in the crank pulley size plus the supercharger cog pulley and jack shaft cog pulley ,and use the impeller speed calculator on Vortech web site..This is the one of the reason's I made the switch to a cog set up.With the 928 motorsports impeller you can spin to 60k up from 53k.

Even with doing all of that there is still some belt slippage that you can not account for from the serpentine belt on the front.
