Ok so i removed the air pump, split air pipe and i think its called the acv (the one that has a rubber pipe with a silencer on it and purges air from air pump). I made block off plates ,put on the dual alt pulley, and started it up. Ran fine,drove fine, but my concern is i can hear my stock BOV really loud now. I was only at 5-6psi. My question is, is this normal or is something not right on it. I love the sound of my BOV now but i like my motor to stay running even more. Thanks

MODS:custom intake pipe, Apexi gt spec DP,Apexi Gt spec exhaust, No cat, and FCD, Boost guage

The valve at bottom of pic is one of the ones i removed and blocked off

 

A custom TID/cone filter will make the BOV noise louder. The ACV and air pump can't possibly affect it.

 

thats the only changes i made to it. Prior to that i heard it a little bit but now it sounds like an aftermarket one.

 

What would it sound like if my BOV wasnt working at all? Lets say it wasnt purging air at all would the same noise occur? I just dont wanna mess up my Turbo or motor. Thanks again

 

Check for cracks in the line going to the BOV. Unless it is vented to the atmosphere like mine is then you barely hear it.

 

wierd thing is i just drove it and not a sound. It didnt blow off like it did last night.
