Enhance Supercharger Output Bypass Valve Normally Open Strategy

Most of the cheaper BOV use a piston in a bore and they leak boost also. The Bypass opens with 1.5 inHg, So it is normally open unless intake ... It fully opens to vent the supercharger boost in situations like reverse, active ABS or TCS, etc. It also stays open during light driving and idling to save on ... 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? That valve is a bypass, preventing boost from building when it's open. It opens when there is vacuum at the diaphragm that operates the lever that pivots the ... 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 wanted to open a discussion around how to approach the topic of setting up the tune for bypass valves that release the boost pressure back into the inlet ... Closed Bypass Valves– Vents to an external air filter or an internal tube for rerouting excess boost pressure back upstream of the supercharger for a more quiet ... when the engine is not under boost, the bypass valve is held open by the intake pressure. It goes on to explain how the bypass prevents the ... That is when you are idling or light throttle. The vacuum holds the bypass valve open so that the supercharger cannot produce boost. All the ... The bypass will shut closed at a couple inches of vacuum, as there is a certain minimum vacuum to keep it open. To bypass the supercharger with ...
