I don't know the boost levels for a 4" or 5", but the one sitting in my garage is about 4.6"-4.7" and I've been told I'll make about 9 PSI with a cam that is similar to yours, that's going to 6500rpm.
They make all sorts of sizes in pulleys, contact Procharger or an authorized dealer, they can probably get you the exact boost level you want.

Guessing on the boost that will be made, and it is only an educated guess, is fairly hard to do, as there are a lot of factors that can throw off what the engine should see. Worn valve springs, belt slippage, too much leakage through the bypass valve, etc. The blower belt stretches after a little use, and I recommend retightening the belt after the first half an hour of use, and the belt has to be tighter than you think it should be.

D1SC Pulleys Well the pulleys I have are 4" and 5" measured with measuring tape. And these numbers are printed right on the pulleys. 4.00 and 5.00
Where would the boost be with the 5.00 inch, 6lbs?
Will the boost be to high with 4 inch w/ the cam and exhaust in my sig and stock internals?
I am shooting for 550 rwhp with the lowest boost possible.
Where do you guys think I will be with either of these? Best guess.
Thanks,

I think it's possible to pick up pullies in 1/4 sizes, so you can go with a 4.75" to get the boost just right.
As far as stock internals go, it's all in the tune. 550rwhp is pretty safe for an LS1.
