Odd BOV question

The set up on my truck is getting changed and Im going to install a BOV even though Im not 100% convinced I need one but none the less I figured Id error on the side of caution for turbo longetivity.

Heres the deal... I absolutely HATE the sound of any aftermarket BOV Ive ever heard so Im looking for a BOV that has a simple "shhhhh" or "chuff" sound when venting rather than the more common whistle, squeek, plays jingle bells, etc. The sound that a semi truck air brake system makes when the moisture traps vent is a sound most ppl have heard and that would best describe what Im after (or something very similar).

So, anyone know which BOV doesnt make corny sounding noises when venting? Ive got a stock DSM piece that I traded for a while back and Im thinking it would prolly work but then again Ive never heard what it sounds like so I have no idea...hell, it could play the national anthom for all I know which would tick me off (not that I mind the national anthom but Id rather it not come from under the hood of my truck).

Re: Odd BOV question

any diverter valve setup won't be as loud since it recirculate the air back into the intake. You could always setup piping/tubing to it w/ a filter or somethign on the end to deaden some of the sound too.

A lot of people like the sound so they started adding megaphone looking cones to the release to make them even louder. I still laugh at the turbo xs RFL, becuase it stands for 'real f---ing loud' :lol:

Re: Odd BOV question

This is what mike is talking about - from past experience with turbo cars with Mass Air Flow Meters (cannot vent to atmosphere) the diverter/bypass valve setup is signifcantly quieter and less obnoxious.

I run the TurboXS and it loud as hell. I scare the crap out of people and have been often told it sounds lie a semi truck. Ild get that one. Or if you dont want to hear it do what Renz said.

Re: Odd BOV question

I had a stock WRX recirc/blow off valve for a while. Sounded a lot like an air brake venting. They are supposedly good up to 18 psi and can be had for cheap.

I had an HKS SSQV on my old TY and it was loud and had a high pitch whistle that you probably wouldn't want. It kind of annoyed me and I wanted the other insert, but never got it. There was a kit you could buy for the HKS that would route it back into the intake. Maybe pick up QWKSTRMS for cheap and buy the intake routing kit separate. :2cents:

Re: Odd BOV question

I use an Audi recycleing valve...
no noise..
and its fully open during vaccum to allow the compressor to spin faster as any
cfm it creates is allowed to vent instead of slowing it down.
I think the last one I found was $30. cdn and if you plumb them backwards
they will hold under a lot of boost.

Re: Odd BOV question

I'll check into "diverter" valves and the other suggestions however...extra plumbing to pipe the BOV back into the intake may be an issue due to space and anything that cant hold 30psi isnt going to work so it sounds like my options are few as of right now.
