I sent a 3" 6-rib Reichard Racing pulley to Andy at A&A corvette to play with. He might still have it. I'm running a 3.2" 8-rib RR on a D1SC and a great bracket setup, and still get slippage over 5500rpm.

If your crank pulley is 7.047", and your blower pulley is 3", that's a ratio of 2.349:1. So at 6,500rpm your blower pulley is spinning at 15,268rpm. The D1SC has a step-up ratio of 4.1:1, and the impeller will spin at 62,600rpm. The D1SC impeller limit is 62,000rpm, the impeller vanes will probably start stalling before that and start beating the air instead of compressing it.
Blu - how many pounds of boost are you making at 5500 RPM? It really looks like you need a larger pulley and a larger head-unit to get the power you want without trashing the belts.
