Guys, I looked to find the right BOV but everyone else seems to want loud. What is the quietest bov that will work well for a BNR stage 3 turbo? I would preffer one that dumps back into the intake tract. Everything I've seen when I searched was for LOUD. This is for an FC if that matters.

 

Turbo XS Type something.. can't remember which model it was but there's one you can screw either a horn or an attachment to recirculate the air infront of the turbo.

 

the hks can be recurculated with the attachment!

 

what ever you get make sure you get a 50mm. Rather have more room to grow that have to buy something twice.

 

i have a tial BOV for sale. it is top of the line and the sound isnt very loud at all. however it doesnt recirculate. comes with the flange welded to the stock ic piping as well

 

How much do you waqnt for it? I looked up the XS type mentioned above and the one's I saw on Ebay had descriptions like "the loudest you can buy" and RFL for real f###### loud so I don't think they will do.

 

Greddy type R works very well, in fact, it can double as a pop-off valve if set correctly. no artificial funky noise just a quiet woosh.... There was a review in SCC a while back, I donot remember which were the fastest, but ther was a wide range of performance between the popular brands. Carl

 

Apex'i twin chamber is pretty quiet, but I don't believe it's possible to recirc it into the intake. That's the BOV that I just took off of my TII. I now have the Tial 50mm BOV and will be using it for my new set up. I have seen several people using the Tial with NO problems at all. I've had the Apex'i BOV for about 2 years now and I have no complaints about it at all. I just wanted a bigger BOV since I'm shooting for 450rwhp on pump gas. Didn't want to leave anything to chance with power levels that high. I also know that the HKS, GReddy type S, Turbo XS type H, and the Blitz DD can all be recirc'ed back into your intake tract if that helps any. Best of luck to you.

I thought the spring tension on the R is hard and does not vent well short of 20psi?

I am running the RS and like it allot. More boost = allot louder but you can unscrew the nozzle and screw in an adapter could easily make one at home depot and plumb it into your intake. Then it would be quite. Due to its nature of only a sound of a whoosh air dump it wont give a pitch noise going into the TID.
