hey guys just wondering what exactly the screw on the BOV does, i know it makes it softer or harder but what does that mean?Thanks alot guys.

 

Does it control the amount of air released? Im not sure, for some reason thats what i think it does, but im probably wrong.

 

hehe i dunno,im trying to find out ause right after i got my clutch installed it used to be a nice PSSHHHH! now it flutters all the time.Trying to figure out why?
BUMP!

 

as long as its functioning, who cares what it sounds like....

 

What kind of BOV? Tighter releases pressure much quicker with a more high-pitched tone. Loosening the bolt would have a less high-pitched sound. As you described PSHHH

 

i wunt to kno too..my frend recently gave me a call asking me wut he shud do about the setting on his BOV(greddy incase anyone wunts to know the type) i really didnt kno wut to tell him so i assumed it was sumthing like the wastegate and advised him to use the softest setting since he was only boosting 4 psi...so yea, i wud also like to know how u shud tune the soft/herdness of ur BOV

if it's fluttering the vacuum source for the BOV is probably disconnected - make sure the vacuum line is securely connected at both ends and it's not leaking.

adjust the screw on the top until no air is escaping from the BOV at idle. too tight and it won't open fully, too loose and you'll have a boost leak through the BOV.
