Stock BOV put to atmospheric-consequences?

[maxash0775]

Say I was going to remove the recurculating tube on the BOV and leave it open to atmospheric and then go to LOWES and use a piece of PVC and hose clamps to block off the hole on the intake tube. What would happen. What would be the effects. Not saying I did it of course, but to broke for BOV at the moment. Remember mean section so no name calling, or at least keep it to a minimum. Thanks

Well one time I was working on my car and for got to reconnect that hose and drove the car like that for a bit made that bov noise but the car would idle differently and stall out at times.But never plugged it up like your saying so not sure on the out come.

basically you're venting air to atmosphere which the AFM has already accounted for and therefore has dumped fueling in for - if you remove the recirculating air the engine will momentarily run rich whenever the BOV actuates. I found I actually improved fuel economy and drivability felt much better when I ditched the SCI twin trumpet BOV and went back to the stock recirculating one.

It won't run.

 

[LIV4PSI]

The post above is right. It won't run until you at least plug the hole in the intake. And once its plugged, then it will run horrible under idle and when shifting still. The stock BPV is very capable, no point in replacing it.

Say you just try it or use the "search" feature.

Every DSM/vr4 is different on this subject. Some will run without a hitch (aside from wasting fuel) some will bog stutter and die. I can't explain why.

The simple answer is stop while you're ahead. You have no reason to do this, do you? Because you want the noise? This isn't 1995 anymore. Save your money till you can get a different BOV (and still recirculate it) or save you money and get something that you can tune For having it venting to atmosphere.

You can do this if you run a blow-thru MAF, such as a GM MAF, with a MAF Translator, or a SD setup such as the archaic HKS VPC, or better yet, ECMLink with MAP and IAT.

ECMLink will also control a GM MAF natively now as well. If you're running a draw thru, karman vortex MAF (i.e. stock airflow meter) then you'd be doing yourself a huge disservice to VTA (vent to atmosphere), it's flat out stupid. Don't do it.

For example.. i had a friend who did this at the track... he was running high 15's in his DSM. I helped him plumb his BOV the way it was SUPPOSED to be, and whaddya know? He was running high 14's (a full second faster) on his next passes.

He wasn't talking just about venting the BOV. He was talking about driving it with a huge hole after the MAF in the intake. I won't run at all with the intake like that. If the intake is fully sealed and the BOV doesn't leak, the car should only run rich when the BOV vents. Long story short, he needs the aforementioned PCV plug first, not second.

Also, a MAFT or even better a MAP based setup is the proper way do it.

If you vent your BOV to atmosphere DR1665 will stab you in the face.

I don't know how I misread that. Yea if you do that you're just a dumbass.

 

[xaisomboun]

My take is, don't do it unless you do the MAFT way.
Unless like what was said previously that you could live with the crappy MPG and a slower car!

And know ye this, Bakersfield, I do so with an exceptionally sizable lexicon at my disposal capable of furious vengeance and severe mental anguish.

Besides. You live in California. It's illegal. Do you really want to break the law in order to get your car to sound the FAIL SIGNAL every gearshift? Tsk, tsk.

 

[mitsuturbo]

I'd think a loud BOV in CA would be a good way to get pulled over. They KNOW that sh*t's not legal.

 

[Vr4junkie]

Yea tell me about it cops are dicks out here its ridiculous i've gotten so many fixing tickets for headers and little things like aftermarket air filters. But since the car did come turbo stock wounder if you can get away with that /ubbthreads/images/graemlins/dunno.gif

 

[ktmrider]

^^ Not in CaliFornification you won't!

Those folks know cars and "mods" better than most of us do. It's way easy revenue for the state and boy do they love their untaxed monies.

Even if the mod is CARB legal they'll many times issue the ticket then make you get it reversed.

 

[Vr4junkie]

Actually no they won't give you a ticket Back in the day when I used to have a Honda I had all bolt ons but every thing had a CARB number cops never told me nothing when they checked it out...but I'm going to look into that it would be nice to have that bov noise.

If the cops aren't enough of a deterrent for you, the car is also going to run like sh*t.
