Supercharger Bypass Valve Normally Open The Secret to Unlocking Power

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 ... 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 ... It's wierd because the vacuum under normal driving holds it open and closes by spring pressure under boost. ... valve open from the intake ... I have a 2013 RT 6 speed and recently put a Magnuson supercharger on the car running 6 lbs of boost. Runs and drives great. Only issue I had was ... I'm talking about vac in the inlet manifold. Which is where you would normally draw the vac from to open a bypass valve. A bypass valve is not ... So the valve stays open. But when you step on the gas and the vacuum indicates that you are asking for more power, the valve closes so that the ... So you have their red 'Race Valve'. All bypass valves used in supercharged applications should be normally closed with the engine NOT running. And that is normal for the valve to be open when the bypass valve actuator fails. I don't think it is a common issue but it is a mechanical ... XK8 / XKR ( X100 ) - S/C Bypass Valve Actuator - ?Also if the supercharger bypass valve vacuum actuator is not working and stuck open you ...
