This is a compact and lightweight by-pass valve that is capable of holding very high boost pressure without leaking. This is an updated design that reduces the control volume by 30% allowing for extremely fast venting of boost pressure without leaking. The updated design reduces the control volume by 30% allowing for extremely fast venting of boost when actuated. 

• Updated design reduces control volume by 30% allowing for extremely fast venting of boost when actuated
• Compact design allows fitment in a confined engine compartment
• Lightweight components create less inertia and can respond faster than heavier components
• Uses banjo-fitting vacuum port which provides 360-degree adjustability of hose routing
• Piston O-ring seal is twice the diameter of the old design allowing more seal compression and reduced wear
• Adjustability of the spring seat is no longer needed to the updated spring and seal design which provides a 60% increase in clamping force at peak boost while maintaining similar operation at idle and transient loads
