Sorry Couldnt help it, but a TS makes a great noise IMO and people started to recommend TS blowers. I am making over 400ft lbs of tq at the wheels from 2600rpms.
Makes for a very fun street car.
EDIT** Also just something I noticed is that with the SAE correction my actuals were even higher. Crazy. I love my whipple and Justin @ VMP is the man.

Anyone from NJ know of some good shops? Not sure yet on what I am getting but got an estimate for the Paxton at it was around $1500, Do you think i should be able to find something cheaper from a quality shop?

I'm not 100% sure but I dont think the vortech kit even has a blow off valve, on my paxton 2200 kit it has 2 bypass valves that recirculate the air, the only time you need to get bigger bypass valves is if your going to up the boost to more than 12lbs or so. the whole loud blow off valve thing is really an import fad, hell they even have different baffles you can put in to make it sound different when the air is escaping. GAY.
Get yourself a small air tank and electric air compressor used for air suspensions. Mount the tank and compressor in the trunk and run airline outside to an electric air valve. I'd go with a 1/2 inch valve and line for a big whooshhhhhhhh sound.

With a ProCharger, the surge valve operates by vaccuum. Under normal driving conditions, it stays open to vent excess air the engine is not using. Under heavy acceleration (no vaccuum), it closes to allow boost to build.
If you hold a gear longer without excelerating, the valve is open and is allowing more air out. That, in itself, makes the whooshing noise. It sound kinda nice at about 1700-1800rpm in second gear putting around the neighborhood. Pretty much sounds like a jet going by.
When you hit the hammer, the air noise disappears (unless you have an F1,2,3), until throttle is released.
So, it doesnt work like a blow-off valve in the traditional sense.
