Stock BOV/BPV leak test
So i thought I'd leak test the stock bov/bpv. you'll have to turn the volume up for the video
:08 pressure crosses 25psi and you can begin to hear it leak.
:15 pressure gets to 28psi and leak becomes very audible
:18 pressure increased to 30psi and it leaks really bad
:32 pressure reduced to 25psi leak decreases but still there
:40 had to drop pressure down to 20psi for the leak to stop completely
I would have done the hks i have now but the silicone seal blew off of my rig at 45spi with no leaking.

the interesting part is that when it started to leak i had to drop the pressure all the way down to 20psi before it resealed.
so for the stock turbo guys; after your boost spike your leaking all the way down to 20 psi making it even harder to get the stock turbo to keep pressure

Good info. The problem is though that there is a big variation between stock BOVs. I don't know if it's a quality control issue or what. My BOV does not start leaking till 28 psi and closes back around 24-25psi. I was able to test 2 more and one held at 20psi and the other held around 25psi.
