Message: [QUOTE="Blowby, post: 329994, member: 711"] So that is where the gate is opening. Example: xx Psi spring force + Actual psi on top when it opens = Drive pressure on your setup now. A few things to check - [LIST=1] [*]Spring force is not 25psi - Apply regulated pressure to the port on the bottom of the WG. Determine the psi needed to lift the valve. [*]Diaphragm has a leak - Apply regulated 30psi to the port on top of the gate to see if it holds pressure. [*]Ring on the bottom of gate (where valve seals) is installed incorrectly. - Make sure it is not upside down. [*]V-Band clamps are not sealing - Check that the clamps are aligned and check for any exhaust leak in this area. [*]WG is faulty - Remove and install V-Band plates to block off opening. [*]Turbo has high DP - Install more spring force (stacked springs-smaller diameter in the center). [/LIST] If the WG is functioning properly then the gate will only open when there is more force pushing up than force pushing down. It's that simple. Keep at it! [/QUOTE]
