How To Quickly Test Your Boost Bypass Actuator

Boost Actuator | SVTPerformance.com In this video, i demonstrate how to quickly test your boost bypass actuator. this method doesn't require any special tools or technique. #1: cap both factory lines going to the boost bypass. #2: take the same line that goes to the frps, which also goes to your factory boost gauge, and "t" into it, then run to the top port on the boost bypass, and leave the bottom port open to atmosphere.

Boost Control Solenoid Maintenance And Boost Control Actuator Test For Low Boost* - GM Forum ... One of them ramps the throttle so slowly that the bypass will rarely close under normal driving, the other is brutal, can barely touch the throttle without bringing the boost on. In this picture, the blue line from the left of the boost bypass solenoid should be unplugged from the sensor that i made in yellow and plugged off carefully using a bolt or screw or something. A quick test of the wastegate actuator is this: with the engine off,remove the vac line from the actuator,pull the wastegate rod up with your hand and then put a finger over the vac line port and release the wastegate lever. It's a pretty simple mechanism. you want to make sure it's adjusted properly. if the actuator is not fully closing the by pass valve, you're not going to be making boost. the actuator has elongated holes on it for adjustment. if you open it manually and release it, the spring should snap the by pass valve closed.

To test the bypass valve actuator (item 1): disconnect the attached hoses and remove from the supercharger, depress plunger, place finger over 1 port at a time, release plunger, the plunger should not return to normal until you release your finger. Try removing the hose for just the boost gauge, pressurize the line with compressed air or blow in it or whatever then cap it off and see if it leaks down. this will tell you if it's the gauge/tubing or the s/c. I took it to the tuner to make sure the tune was supporting the extra boost and that the engine wasn't detonating. under partial throttle/partial boost, the engine was pulling a lot of timing, causing some knock. Single port bypass valves should be connected to the vacuum side of the supercharger (inlet side) for best results. the opening vacuum level is determined by the spring pressure installed inside the bypass valve.
