My bet is that he's revving while not under load and expecting to hear it.

 

Actually we crush them to make more power stock

 

No, Im not just reving in nuetral, Im trying it under a load of 9 psi, the vacume port im using pulls alot, as soon as I start the car, It slams the valve all most wide open, then I drive it and get the boost up, and I barely here a faint phssss. I cant tell what it doing , because i cant ride int the engine bay, while going down the road.

Is it suppose to stay wide open while in vacume, or what?
Its just vented into the air, but I can hardly here it. My exhaust isnt loud , so I dont understand why I cant here it.

Help me out people.

 

I ran into that issue before.
It depends on where you mount your BOV. The further it is from the TB the lounder it gets. Try relocating it further down towards your stock air filter.

 

at 9 psi that ---- should be loud enough no matter where it's mounted.

There's something else wrong here.

 

this must be the problem i'm having. I am running open downpipe until i can get my car to a shop to have my exhaust all fixed up. I took my car out for a spin yesterday only revving to 3k rpms because i basically have no fuel managment because the ecu chip i have isn't working properly and I had to run off of the stock p28 maps. Anyways i didn't hear my 1g dsm bov at all, but again thats probably because i am open dp and i wasn't building much boost.
