I recently installed the RMM Supercharger on my car and I remember sometime ago someone talking about having a Blow-Off valve that they got from Area 51 and a smaller pulley for more boost from Vortech.
I cannot find a telephone number for Area 51, also does anyone have recommendations for aftermarket an aftermarket boost gauge.

Just wondering...I could be wrong...
Aren't blow off valves for turbo applications? And it's usually to keep the turbos spooled up during shifting? What good would it do for a SC when it's not the exhaust that is driving the turbine but the belt and intake air? I am a little confused. Can someone clarify this for me? Thanks!

Why did they close down, seem to be a pretty good operation from what I heard on these boards.

I am not the smartest guy on the block but I believe that the purpose of the Blow Off Valve on a supercharged engine is due to compressor surge, basically meaning that the throttle is closed but the supercharger is still creating boost since it is spinning via the crank. When you are slowing down or shifting just like with a turbo, you need to have a place for the boost to go when it is excessively high and with a blow off valve, the air is released out of the supercharger system. If not, under high boost situations, the pressurized air would be forced back into the supercharger which might cause damage to the unit intself. Don't quote me nut I am pretty sure that is what would happen.

Why a Blow-off Valve (BOV), is needed?
--To eliminate compressor surge when changing gears. Excessive backpressure is created when the throttle is closed during gear changes or deceleration, causing turbo cavitation. This is detrimental to the life of your turbocharger; however fitting a BOV will substantially improve this problem.
--By installing a BOV you will significantly reduce turbo spool up time. You will notice a substantial improvement in response from your turbo between gearshifts. Boost will come on earlier giving an increase in torque at lower RPM.

That was me. I have almost every pulley for that S/C what boost are you running and what do you want? I have tried ALL the pully sizes made.
