I like BOVs. And I'm a girl. And I'm blonde. /flame on
This is a discussion on "The BIG BOV thread" (Where all bov question threads get merged) within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; I like BOVs. And I'm a girl. And I'm blonde. /flame on...
I also have an 06 wagon and installed the K&N drop-in filter along side with stage1 cobb base map. Everytime let off the gas, a very noticeable (with stereo volume down) "wwhooosshhh comes through. If you take out the silencer elbow, I'm sure it will get a bit more dramatic. Now that I'm at a stage 2, i can't tell the difference because the downpipe noise covers itOriginally Posted by chimchim
My friend put a TurboXS RFL blowoff valve on his stock 05 STi, and it sounded fun for about 5 minutes, but his car ran like sh***. It was backfiring, idle was rough and sometimes stalled, it was awful. Good thing it was a freebie.
Its a recirculating valve just like stock but give the sound clip a listen.Now imagine silencer/snorkus removed.
Installed my Agency BOV 3 weeks ago. works like a charm no boging no richness no abnormal idle no change. i have it set for 50/50 and the spring tension is set very hard just like the stock. it's so right because it only blows off when im at WOT around .8.5 bar - full boost. so no boost creep or leak. it doesn't even seem like i got it installed because i only have about 1,050 mile on my STI. Full synthetic today
So a bought my car used and it came with a afternarket BOV. I recently replaced it with the stock unit, however I'm afraid I missed installing a part in the process, I'm not sure though because the car runs fine since reinstalling it.
When I took the aftermaket unit off there was an o-ring in the BOV that I did not reuse when installing the stock unit. My question is, other than the gasket inbetween the BOV and intercooler are there any other gaskets/o-rings or parts that I might have missed. I don't think I missed anything since the car runs great, I just want to be sure. Thanks for any help.
there should only be 1 gasket between the i/c and the recirc valve. just as long as the bolts are torqued right and the hoses are in the right order. you stated the car is running fine so seems that you got it. which brand was the aftermarket bov ?
have you ever been 4 bagged ???
I have no idea. I'm going to try and find out some information on it cause I would like to sell it if I could. It is appearently a 50/50 atmosphere/recirculating split. It says GFB on the top. I'm going to look into it and see what I can find.
Thats Go Fast Bits aint it. and its suposto be a pretty good one
Yeah, that's the one. I just found it. It's a WRX Hybrid (non adjustable). Looks like it's pretty pricey if you get them new.
if it was set up 100% atmo you may have missed the return hose?
two hoses attatch to the stock BOV. The return hose and the signal hose. Also, make sure the signal hose didn't get kinked somewhere because that will mess up the opening/closing action. Make sure the BOV isn't stuck too..try sucking on the return hose nipple (to simulate a vaccum) and push on the valve with your finger...you should be able to get to to move a little bit. Also, make sure the OTHER end of the return hose is attatched. Some people disconnect the OTHER end of the return hose to change the sound the BOV makes.
make sure the hose clamps are tight. I ended up replacing the spring clamp on the return hose with a regular screw-type clamp...its MUCH easier to install/remove and I got tired of almost losing an eye every time I need to pull the IC.

It is better to have others think that you are a fool than to open your mouth and remove all doubt

I just installed a GReddy RS BOV on a 2002 WRX and noticed a slight hissing noise comming from the BOV area at idle. When you rev it a little the sound dissapears but returns after a min at idle again. Is that a boost or vacuume leak?- i double checked the hose clamps for tightness. Also I just read that an atmospheric type BOV can hurt performance on cars like these that are ment to recirculate the air. Any truth to that? Thanks guys-
bov performance hits/ problems have been covered a thousand times on this board this week. Search. .
As for the bov leaking. Ensure it's not your vaccum lines first. Did you buy it new or used? If used have you opened it up to see if the prior owner cut the springs at all on it?
Edit: spring; typeS=1 spring RS = 2 springs.
Hey guys i just got done installing my Forge BOV which sounds sweet. Car runs fine. I also have a K&N typhoon intake system. I just have a quick question, Is anyone running stock boost and the forge on an STi? and can you tell me which spring and how many spacers you are using? btw i will post up some pics and if anyone would like me to a step by step on the install.
Wow no one? come on now i know most of you hate intakes and BOVs but i bought an Intake that is actually good for the car and the Forge BOV is supposed to be considered one of the only ones to not hurt the cars performance.
