Hey I had this on my car since 96 and never thought of adjusting to make it sound louder, Anyway I want to play it cause I am bore,on the the bov top plate it has 2 arrow {1} facing counter clockwise saying soft, and the 2nd arrow facing clock wise is saying harder, if I want to amke it louder do turn the screw to harder position? Khris

 

you know...you could just try it and see what happens??



why do you need to ask about this?

 

Like anyone really cares about how loud your bov is.



Just dont end up with it too hard and not doing its job or too soft and leaking.

 

it doesn't make it louder khris. it adjusts when it opens up

 

id think if u make it harder, the higher pressure buildup will make for a higher pitched louder whoosh whistle whip whatever u wanna call it and softer will make for a more raspy... sound

 

Well like I said was bore @ home nothing to do and in NJ we been having crappy weather everyday it rain so I was looking to do something for the fun.Thanks Jon and Mike
