BOV Question???????

[BOOstGhost]

I'm planning on getting a greddy type-s BOV for my 1gb laser rs....since the OEM BOV leaking boost.....so i was juss wondering wit BOVs in general....what do you guys do with the return hose???? especially for BOVs that are 100% atmospheric????? juss curious hope to hear some feedback....late

Make sure you get one that can recirculate and connect it so it does so. If you don't there is a 99% chance it will run like shit.

How are you so sure that your BOV is leaking? Most 1g BOV's don't leak until you boost up to like 18lbs or so.

Do yourself a favor and get yourself a BOV that recirculates. But if you do have to get something that vents, then cap off the hole on your intake pipe and throw the tube aside.

I know my 1g BOV is leaking, you can feel the air come out of it at idle and its alot.

Get one of these leak stop kits. They make the 1g BOV sound amazing. My friend has one and it sounds so much better than my Type S

the 1g bov does leak at idle. they all do that. just hook it back to the intake and it wont be a problem.

It's Spose to leak at Idle...

(EDIT- Dsm beat me to it.)

Waitaminute, "out" of it? It's opened by vacuum, so at idle it's open almost as far as it will (it'll reach full-open at highest vaccum, when closing the throttle at higher RPMs), and the "leak" should be _in_ to it. This is part of why running vented is bad, you're creating a huge unmetered, unfiltered vacuum leak at idle and on every shift.
You should feel air going _into_ it at idle, if you have the recirc tube disconnected.

Sorry to be a thread jacker but when I was doing a psi test over the weekend I found that my only leak is coming from the BOV. When I pressurize the system above 5psi air starts coming out of the recirc tube. That means it's not the flange it's the BOV itself correct? I thought 1G bov's didn't leak untill 18psi in stock form. Do I have a bad one? Has anyone ever had a 1G BOV leak under 10psi??

Wait a sec! I run a turbo xs RFL which is purpose built to vent to the atomesphere. So many people hear how DSMS run shitty when using open atm bov's but that is so untrue. They only run crappy when you run a BOV that is either A) supposed to be vented back to the intake or B) the company claims it can be run both ways. I have run a Greddy open (who claims it can go both ways), CRAP, stalled at idle, leaked like hell at part throttle. Then I ran a Blitz super sound, no more stalling at idle but leaked at times in part throttle conditions. Then I got a turbo xs type H, best thing I have ever bought. No leaking, even at part throttle, idles fine, never stalls, runs GREAT. Now I am using an RFL and it is much the same just really loud. Nothing gets a throaty SS to back off at the line like a couple blips from an RFL. Chicks dig it to no end too.

Furthermore, the whole unmetered airflow screwing tuning up is also a bit false. Its not a BIG amount, in fact, it didnt even show up on my buddies TMO datalogger, so its not really too big of an amount that would be detrimental to performance. Also, the best BOV on the market which all the big name racers use is an open atm (tial) so that also says something in itself.

All the people that use that are running standalones that elimiate the stock MAS

Please disregard this post.

Venting on the stock MAS WILL affect your performance, WHETHER YOUR ASS DYNO NOTICES IT OR NOT.

You want to vent? Get a MAFT or a standalone.

I guess we were all just wrong.

basically your wrong man. stop telling people that, check the rules and stop spreding false information. With a DSM you have a MAS that is draw though and the "CBV" cough cough wink wink is after the mas. The car is made so that the CBV sends the air back into the intake so you dont lose mettered air that the MAS thinks is going into the engine. If you do vent your CBV your losing air that the MAS says is supposed to be there and it causes some problems. The BOV that are "made" to vent are not made to be ran on a Stock DSM intake system, they are made to be ran on a blow through setup, standalone, blah blah blah and all that, not for sock DSM. And that would be the true information

o and on a stock setup DSM runing vented will cause you to lose a tad bit of power, but hey, who cares if it runs bad and you lose some power, its sure does sound good right?

 

[nore474]

I know its off topic but will a HKS SS BOV work with just exhaust, intake, mbc and a boost Gauge?

 

[Eclipse96Ryder]

im venting on my type S. I do run a little rich in between shifts, but not nearly as rich as i did when i was venting my 1g bov. My idle is just fine, the vacuum pressure is a bit low (10) but it never has stalled or anything like that. The car does not run like crap. I have heard that some cars run shitty, and some cars run fine. Just try it on ur car and see how it is. The BOV is a lot louder vented, and doesnt affect my car....so I just am going to leave it vented.

 

[sickgsx-316]

Damn, you guys are funny. Dont jump down my throat. Im at talking from experience, I have run both and you guys are lame for reacting to my post that way. You sit here and try and cram the facts down the throat that are true and make perfect sense but at the same time I have actually tried these things out myself instead of listening to conventional wisdom and IT WORKS GREAT, despite all that mas crap. The unmetered air that you lose from venting is not noticable on a DATALOGGER!! There are at least 4 other DSMers I chill with regularly that would spout the same crap that you guys just did,I let them run my RFL for a week, then they bought their own. I used to be just like you guys when people asked that question, then I actually tried it.

Have you ever run an open atm bov? I lost no time in the quarter whatsoever. One thing I am is consistent at the tree. Even passed smog with a type-h venting on there. In cali, at a local Chevron. With 3-inch turbo back, and an upgraded turbo, Injectors and an AFC. Spreading false information...bah, i never once said anything false. I speak from experience. All cars react differently to running open, mine didnt mind once I found the proper BOV, 4 guys I chill with, and 3 DSMs at my college run fine open as well. My girlfriends 1g talon, didnt like it at all, kicked and bucked and refused it the entire way. It works for some, it doesnt for others, dont jump down my throat for speaking from experience.

Well then why not head down to tracey or milpitas and see what some of the sub 12 dsmers are running. You'd be surprised. Venting works well with SOME cars. Prostreet's FMIC kit comes with a tial, that is vented, and they have numerous customers running their kit on the street on a stock mas and it works fine. Have you ever run a bov made to be vented? I seriously doubt it which is why you keep referring to my post as "false info." On paper, it makes perfect sense for venting to screw things up, however, the air being lost is rather insignificant IMO and from personal experience. My cars EGT's, A/F and tuning is fine vented.
