Revolutionize Supercharger Performance Bypass Valve Normally Open for Power Gains

So we added a stronger spring to overcome the vacuum condition that it sees so that it will not open as soon or as much. Our BPV closes at 6" of vacuum, as ... This is at the pressure side of the bypass valve and if defective it can make the bypass actuator act weird. All well sealed? No vacuum leaks? Basically the boost solenoid is to open the bypass valve to bleed off boost. This is done to prevent overboost and control boost say in ... During idling or part throttle non boost operation, the bypass valve is held "open" by engine vacuum (10"-22"Hg). This allows the compressed air ... So I am FULLY aware of the fact that normal operation shows a supercharger bypass/surge valve to be open at all times until it sees 0 MAP or ... The spring is selected and installed to hold the bypass valve open at all vacuum levels and at up to one PSI of boost, and then to allow the bypass to close ... ... normally it is quite ... bypass valve and observe the butterfly opening and closing inside the supercharger itself. My understanding is that under normal conditions, the bypass valve is opened when there's vacuum applied to the actuator. So when the throttle ... ... supercharger bypass valve which would normally control boost/open when throttle closed? The overall boost reference would be taken from ... You want to have your reference at the intake manifold after the throttle blade. and you want your BOV to open when it senses vacuum not just a ...
