hey guys helping a mate installing a boost gauge in his superchargerd 6. but im unsure if i installed the line into the right line on the engine. i tee pieced into a line that go's to a actuator near the throttle body and we took the car for a drive and wasnt showing a boost reading.where is the best spot to tee in or is this ok
cheers Allan
Sounds like you've tee'd the wrong one. I've attached some pics below to show the two easiest locations to measure boost pressure with very little work involved...
The first is to fit your boost gauge vac line to the vac port on the front of the alloy lower inlet manifold under the blower snout. From factory it has a black rubber blanking cap over it as pictured. Remove the cap and fit your new vac hose.
The other way is to tee into either of the vac lines that are connected to the boost tree. The bottom one goes to fuel pressure reg and the top goes to the boost control solenoid. It is also worth noting that the boost control solenoids are notorious for dying and prevent you from achieving full boost. Many (including myself) delete the solenoid all together. There is no need to delete it though if it is functioning correctly.
Hope that helps.
Chris.
Does the gauge just read 0 all the time or are you seeing vacume just not boost?
