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? :confused: Any help would be appreciated, and no flaming, please.
 
HAHA! InnercircleVP, you win the award for the IDIOT of the century.

First of all, he asked about making a "pssshh" noise, which would be percieved by the ears, and thus does not qualify as "looks."

Second all all, he asked in the PERFORMANCE forum about getting his BOV to work so that he could make the pssshhh noise, without the bad side effects. Noise vs. stalling. That's it. We said, no. You can't get the noise without problems. He asked a question, and he answered it exactly as he asked it. Learn to read, and then go back to speedoptions.com.

gonna have to agree.. no, no, no, no, and no incase i missed one.. i use to want to vent.. and i did.. then after recirculating.. i felt how much better my car ran.. this might not be a direct thread about venting.. but it sure is an indirect way to post it without getting busted for it.. which by the above posts seem like u already have.. hehe.. just dont do it man!

if u really want to vent without any problems.. get a standalone, gm mas, vpc etc.. something of that nature.. but if ur getting that JUST TO VENT.. then i suggest u think about wat your doing before u spend A LOT of money just so u can hear some sound..

u want a loud recirculated BOV? get a greddy type s..
 
And an HKS filter with a Dejon Tool intake pipe from the MAS. That's my setup and it's really loud, almost annoying loud. Im thinking about trying to figure out how to make it quieter, LOL..

For guys with 1G bov's the greddy bolts right upto that flange all you have to do is drill new holes in the flange to fit the greddy bov, other then that it's a bolt on affair. No flange needed.

All the ricey woosh noises without annoying side effects.


I think this was the best response to the question.

I seen somewhere that you can buy the piece of pipe that fits in right before the TB elbow and allows a 3" GM mas to placed there. I think this would be your best bet, and it would allow alot more air to pass through the mas.

Does anyone know the site I'm talking about, the cost was around $200-250 + 3" GM mas?
 
yes dejon makes a upper intercooler pipe that fits the gm mas between the bov and the TB so any vented air leaves before the mas counts it, so you can vent to atmosphere, and also you can put a filter directly on your turbo so your spool will be louder, or you could run a tube down for a cold air intake since you dont have the huge mas there

generally not a very good idea due to all of the heat from the radiator going right back to the turbo inlet, but any fan of initial D would love this

a better idea
 
yea a filter in your turbo = bad idea. at a standstill the car BOGGS! bad!
and venting = dumb unless you have a vpc or maft.
 
I am not venting my BOV and never will be. It doesn't run right in my case. But for the people that do vent, haven't you had problems with dirt getting sucked into the engine? I was looking at this site DDG and they actually hooked up a filter to the BOV vent. I see many DSMers that do not run any sort of filter on their stock and aftermarket BOVs. Is this just a chance many of us take, or what? I was just wondering this and I didn't see anything when seaching (awhile ago) through threads about venting the BOV to the atmosphere insted of recirculating it. Personally, if I could vent, I would use a filter. 1g BOVs can be had for cheap, but why buy another if you don't have too?
 
dsmrevolution: I guess you could do the filter thing, but wouldn't you be needing a vpc before you even consider venting it? If anything, give that mod a try on the dodge garage page. I gave it a whirl and love it!

Yes that is true. What is the advantage to the mod on the DDG site? I know that your BOV will not leak pressure until you reach higher psi or even at all, but besides that. Can you give me some details on what it changed when you did it? Its the fast release and slow release that I didn't understand.
 
Okay, in summary: (I did a write up on this in the tech section under the turbo part)

Prior to the mod, there is a little "port" running parallel to the main port that allows the air to prematurely leak thus "weakening" the diaphragm getting it ready to blow. Okay, so with the mod, you have plugged that smaller port making the bov only do its thing at the last minute, so to speak. Honestly, I don't know why you make the new port with the brake line that intercepts that little port perpendicularly. I believe it simply blocks it off so it doesn't do that premature thing, but still prevents it from being "sealed" off. I think that stock that little port worked both ways so this new brake line port allows it to still function at least one way still. Anyway, the mod is now slow/last minute release.

And yes, I did notice a difference. I have a nifty aftermarket sound now and it does hold longer and harder. It is settling to me because I would love the HKS SSQ whatever bov, but knowing the 1g bov are so nice, it was good to modify it to get some sound and resistance.

In reference to the quick release, that is referring to the stock set up. I haven't gone back to it yet, but I made it so I could by putting a nipple in the uicp as close to the bov as possible and capping it. If I want to go back to stock/quick release, I attach a vacuum hose to the new nipple on the uicp and put the other end to the brake line.

I hope to god this helped, cuz it's early and I tend to ramble.

If you have ?s feel free to ask.

It could just be me, but yes, you do get a nicer aftermarket sound when it blows and as it spools up. I imagine if you can combine this with an aftermarket intake, you will get some nice gains both performance and sound.
 
*knows this is a repost*

I just wanted to know if it was ok vent my (stock) bov into the atmosphere, and if so are ther any precautions i should take?Will it change back pressure ect?... or is this in the wrong fourm:p
 
u can vent ur bov to atmosphere, but ur car will idle like crap(and sometimes not be able to keep an idle and stall) and run far too rich, every time the bov opens it robs the engine of air that has already been measured by the MAS and compensated for with the proper ammount of fuel, u need a VPC or a GM mas to run an atmosphere dump bov and have ur car run right
u can just pull the dump tube off, but it will make ur car slower, and recirculating the bov helps to keep the turbo spoiled when u shift, thats y it recirculates back into the intake
 
Here is a fairly cheap solution for the people wanting to vent there BOV to the atmosphere. It helps with most of the problems associated with this practice. It also helps clean up poor idle quality if you are having those problems to. Here is the website for detailed information.
