Just bought a Apexi Dual Chamber BOV for my 3rd gen.

How do i adjust it? Im running about 12-14 psi.

 

yeah i'm wondering about the samething, how do you know how far you tighten the screw or loosen it? is there any accurate way to tell?

Anyone know?

 

I've asked this same question before.
All I got was a bunch of smart asses saying what a waste of money after market BOV's are. No performance gain for big bucks.

Much like my response to this thread, I wish people would just answer the question. Not give their stupid opinions.

For the record. I have two ARC BOV's in my 3rd Gen( I replaced the charge relief valve also).

Hell if I know how to adjust the damn things. (I bought them used).
I adjusted the set screw to both extremes to see what it would do. The only thing I noticed, with the spring tension higher it would shutter the discharge from the valve, slightly.
They do look cool.
