confused on vacume?
#1
ok guys Im confused just bought a proflow valve for the procharger from ebay. when i got it it was bound up but looks new maybe someone took it apart. my question is when engine at idle or cruise you have vacume and valve should be open right? when in wide open throttle valve should close because vacume is gone and your boost goes up right or am I wrong? thank you

Do you have a vac/boost gauge? As soon as you got enough throttle to get to 0 vac, the valve should close and you should start seeing boost. That's how mine works... as crude as the Procharger valve is it works, havn't found a need to change it. Is the one you have adjustable?

yes its adjustable. when i got it didnt want to move or anything had to take it apart . looks like someone couldnt get it to work . I had to even remove the butterfly. Now its doing something i put a vac hose on it when you pull vac on it it opens and a soon as no vac it closes. I going to hook it up to the truck and see if it works under idle and when engine gets reved.

Sounds like you either got it fixed or are well down that road.
