1g bov vent to atmosphere? [Merged 6-8] venting

[TSIAWDTalon]

I have read a lot of "controversy" regarding bov venting to the atmosphere. I want to vent mine, for my own reasons, but I don't want to change from the 1g. Is this possible? Any help would be appreciated, and no flaming, please.

That's exactly why.

I have the TurboXS Type H BOV. It sounds really nice and it vents to the atmosphere. My car runs fine...only real difference is that my gas mileage went down a bit. (associated with running rich) Small price to pay but no stalling at red lights or bogging.

 

[paranoidTSi]

There are certain ones that can vent with no problems, I know the Blitz Dual Drive BOV will allow venting without problems..not sure about others.

That is the answer!


One other thing. Most say it really depends on the car, not just if you can or not. You have to try it for yourself. Black smoke is rich!

I have been venting my Type-S and have had no problems.
I played with the tension screw a little. The car idles fine and seams fine between shifts, although I'm sure it has to be running a little rich in between.
However I really can't tell any difference, between venting and not venting.

I plan on putting the dump tube back on. Logic would be that the car should perform better getting the air that it is expecting between shifts.
I would rather have performance, then cool sounds.

I'm guessing my car would running better vented if I fixed 1 little thing I missed when I first tried it. I left the dump tube opend. So it was sucking in air that was not read by the MAF..... So thats why it was running so f-ed up. I was thinkin, is there anyway to confuse the car into decressing the air. Like to it electronically. Makes the Om'z when the BOV is bumped back in, and measure when its vented. Insert a Cap. or something*RadioShack* that would fool it into thinking air was DELETED from the readings? Is this possiable??

And...

VeinPressureComputer and what else allow you to vent with no problem. The Vein computer is like 1grand? I saw one at a junkyard in a totaled SupraTT. I should have offered them $100. They were hicks they would be like OK.... But I only had a Camry back then....hahaha

venting your bov just makes you car run like complete sh*t and if anyone trys to say it doesnt then leave now, the response between shifts and idle(idle not as much as shift though) just sucks. those of you who are venting go put a return tube back on and tell me how you like it now. If thats all you want is noise and this is what im guessing sense thats all you said, go get any of the aftermarket bov and slap it on and plug your intake pipe, it will make tones of cool noises for you. now if you want some more noises go to any dsm shop and look at the external dump o2 housing then you will be making some real noises.

^ doing that will make your car sound realy cool but at the same time make it run like a 89 broken down civic, i dont recommend it if you dont have all the supporting mods for it(gm maft, bigger turbo and full exhaust) but you ask for noise and i gave it to you.

Seems everyone is arguing what the term "ricer" means and forgot about the guy who asked the question....

The answer is yes - you can simply pull off the hose coming from the BOV to the intake and cap off the intake side. The car isn't meant to run that way and there's a good chance it will have negative effects (maybe not noticable without a logger), but if you're hung up on having it loud, you can do it.

You might want to read the FAQ forums - it's the first forum listed at the top when you came in - here's a post from there:

Buying a VPC just so you can vent to the atmosphere makes little sense. You can buy a GM MAFT and an LS1 MAF and it will be cheaper, but still, you'd be putting yourself through a lot of trouble just for some loud noises between shifts. It would probably be easier to just buy a different turbocharged car that won't suffer from the negative effects of venting to the atmosphere. You wouldn't be forced to spend so much money and suffer from headaches trying to tune the car to run right.

For those keen on defining rice, please start a thread doing so in the Hangout.

Venting a DSM is bad. A glimpse at any of the 839 posts which our friend Mr. Search returns will confirm this far beyond any debate. Still, many choose to commit this act of treachery upon the fine brotherhood that is DSM. When you wake up sizzling in the depths of hell, you venters will know why.

As stated many times, the BOV is opened by vacuum. During most part-throttle operations, and during deceleration, you will be sucking raw, unfiltered air straight into your throttle plate and onto your valves and cylinder walls. Yet another sensible reason to not vent.

And for now, after a gruelling, harrowing, and quite exhausting bout of editing, the discussion is closed.

not gonna do it cuz it will only cause problems but it sounds interesting.. what do you disconnect to do it? does anyone have pictures?

 

[sherfield2002]

but you're gonna do it anyway, aren't you.

Not really anything to picture, just disconnect the return hose and plug the hole in the elephant trunk.

 

[boostdevil]

here is my bov, just like defiant said there aint much to it you just have the tube that goes from the bov to the intake taken off so the air is just venting to the atmosphere instead of the intake
and dont bs, you are going to do it otherwise why would you ask??

true, true

 

[1FlyTsiVT]

yea.. but not driving like that, my car has enough problems anyways.. need some sounds for my video and stuff though

 

[JessesTalon]

It goes car by car. Don't tell people there car won't run venting, cuz some people's do. depending on the condition of your car.

I run venting, and never once had a problem. my idle surge is from my ics motor gone bad, and my car spools up alot quicker venting...

Try it, if your car won't run... don't do it... all you have to do is take of the clip held to your bov and tube, then d/c the tube, and plug the tube. and be happy hearing the pssssssshhhhhhtttttt like me

 

[JessesTalon]

and if you want, you can put a rubber hose 3 inches long over your bov and have it venting after it goes through the rubber, it sounds sooo cool. you can also put other stuff on the end of your bov to make it sound funny (maybe a lil bit at the end of your video its hella funny

 

[Talonryda17]

Don't do it

there are alot of sound clips of BOV's available on the internet, use those


but what these guys are saying is true, some cars will run venting to atmosphere, my roomate uses the Pruven Perf BOV (Modified Greddy Type-S) and he vents to atmosphere with no problems at all

 

[1FlyTsiVT]

that "elephant trunk" tube i removed? does the bov make a different sound then when it is open?

 

[boostdevil]

yah if you disconnect the part of the tube that goes to the bov then it makes a huge difference in sound! but if you dont cap the end where the tube goes into the intake then it will run like total azz

the problem is everyone wants that , its not even about the perfomance. You want to hear it ?, man just get a 1G bov and and aftermarket air intake and you can more then hear your ricer spit air.

Sure it is. I know how to fix that.

and my car spools up alot quicker venting...

Let's say _you think_ is spools up quicker. The intake wouldn't know if it's vented or not on acceleration, unless your BOV is open all the time.

 

[boostdevil]

thats funny to because it was the exact opposite with my talon, the spool up was horrible when it vented compared to when it was recirculated, but in my eclipse it doesnt really make a difference in spool up time
