i've got the apexi twin chamber bov. what exactly is the purpose of the adjusting screw and nut on the top of the bov? and how do i know what to set it to? any help is appriciated. thanks

 

no one knows?

 

not sure about it exaclty but I would assume that it's to adjust when it blows off, as in how much pressure before it releases.

 

adjustment screw is to tighten and loosen bov. i'd leave it where it is and if its leaking boost prematurely then tighten it a lil and if its not opening up quick enough and u get some compressor surge then loosen it a lil

 

thanks
