^^^its nice when you route it via vacuum. It's instant open and close depending on throttle.

I have a Precision BOV. While I hate precision as a company, I love the sound of this thing. It doesn't have that high pitch blow off but rather a deep pssssh. If you want it louder, just run more boost. I have noticed when I switch turbos that the volume of air (not just pressure behind it) has a lot to do with the sound. When i was running a pte 6062 it was a a good bit deeper sound vs the bw 257 I have now

Thanks guys. Im currently running a 6266 and am upgrading to a 6466 turbo. I run a maximum of around 27psi and the BOV is quiet no matter what level. Vacuum routing is proper. I have suspected a boost leak a bit though have not had time to pressure test. Im not a fan of the high pitch stuff from HKS personally. I like the sound common on supras with a psshhhhh and higher pitch when higher boost.

Just verified that i am running the 11 PSI spring

I had the Tial Q in my Integra and it sounded amazing! It was pretty loud. Make sure you have the right right spring, as they run pretty stiff. you may want to run a slightly softer spring.

Any sound clips ?

You want loud. My QRJ is obnoxiously loud. Sounds like one of those airport toilets that flush with the force of a waterfall.

If only there was a way to record audio/video with a handheld device and easily upload it to a free video hosting website and link that to this thread so the rest of the S2K community could benefit and truly compare BOV sounds instead of typing out how they sound and leaving it to ones imagination. One could only hope.
