hello everybody.

i got a apexi twin chamber bov on my car. and i think it needs adjustment. i think its leaking boost.


i'v searched. and tryed to adjust it.

one guy said:
"To adjust the greddy right,you got to idlethe car,like around 1000rpms(might have to idle it little higher to feel anything) turn the adjustment nut towards soft until you can feel air rushing out of it,then slowly turn it towards hard until air stops coming out,then give it like a 1/2-1 turn extra and your done."

but i dont feel any air coming out of it when the spring is loose....

 

 

anyone?

 

 

 

Though i know nothing about the Apexi, you're not leaking boost if you're not feeling anything out of it at idle. Every aftermarket valve i know of closes with a spring, plus uses boost pressure ontop of the spring, if you're not leaking air at idle, the only thing to be concerned of is a fluttering sound which is compressor surge. I adjusted my Greddy until i heard no fluttering when letting off the throttle.

Maybe it has some type of check valve system in it so it doesn't leak at idle so MAF cars can run it without running bad?
