[QUOTE="JP_Stang, post: 12395084, member: 112328"] You want to make sure it is large enough to release the air the SC is making. Unlike turbo's, centri blowers are blowing air the whole time they are spinning, obviously. I would try to choose one of the BOV's I mentioned if it were my car. You don't really want to run a weaker spring than a 3psi spring. Remember that the blower will create more boost the faster it turns and you won't always be wide open throttle at higher RPM's. I have noticed that half throttle acceleration is not the best thing to do with our type of setups. The reason is because the blower will start building boost and half throttle is enough to shut the BOV. Since the motor is not pulling in all that air that's being pushed, I can hear the blower's impeller start to shutter a little, which is what you don't want. So basically, I like to keep it real easy or push it hard. I personally would go with the Procharger unit or the Tial unit w/ the 3psi spring. But there alot of guys running the Vortech Mondo's making alot more power than I am with no issues at all so basically it's personal preference. Also, the spring used in the BOV is usually determined by the amount of vacuum the car naturally has, not boost. I read that somewhere but I can't remember where. It was quite awhile ago. I think the way it works is the vacuum is what actually pulls the BOV open and when you get to a certain amount of throttle, the car goes to zero vacuum which shuts the BOV. [/QUOTE]
