has any one found the right adjustment on an apexi bov for stock twins @10 psi?i have tried to adjust it my the vacuum and all but i was wondering if anyone has counted the turns ?this is the dual chamber one .thanks

 

The adjustment on the Apexi BOV is just for sound, it's not a boost controller (if that's what you are trying to do). In other words, the holes on the ring denote the loudness of the blow off. The larger the ring you are using, the louder the sound.

 

no i'm talkin about the spring that u adjust for the psi .it can be adjusted for low or high pressure .if its not set right it will leak under boost.

 

Unless you are running high boost, you don't need to touch it.

 

well that would be fine but it has got tobe set to low cause i'm loosin boost .but i dont want it to tight cause that has even worse results .!??

 

Just follow the steps. Tighten it all the way, and then while the car is running, loosen the bolt until it effects your vacuum/idle. When that happens, just tighten it back a little and there you go.

 

That is unless you have another vacuum leak. I have one MIA vacuum leak yet to be discovered and with the spring all out it does not effect my idle vac! It won't hurt much to have it a bit too tight. What is your vac. at idle?

 

looks like about 14-16.i have had problems with a vac leak as well ,i changed the y-pipe coupler and i went back to my stock bov ,i havent had a chance to run it and see if that solved it .

 

If you have the same vacuum at idle after the B.O.V install as you did before you are set. If not tighten the spring and bolt a bit until you get to the vac you were at pre-BOV.
