venting greddy bov

[sybeks]

i just got a 98 gsx and previous owner has the bov vented to atmosphere, my question is should i vent it back into the cold air intake manifold where the plug cap is, car seems to be running ok as is but i heard that venting to the air is probably bad idea.

You should recirculate your BOV back into you intake.

Recirculate Your Bov......dsm Rule #1

ok thanks, i believe previous owner was trying to impress people with the sound

yea please for your cars sake, remove the plug and recirculate it... BCUZ i wanted to see how it would sound if i plugged it up and just vented it to the atmosphere, so i did so for 1 day... The check engine light went on that night and now i have to replace some shit
plus you lose fuel economy ### you engine runs richer

I get a huge laugh out of guys who vent just to make their BOV's "louder".

A vented valve on a car making 10psi is no where NEAR as loud as a recirculated one on a car making 25psi.

get a blow threw setup and vent to your hearts content

I know that if you have a stan alone, then recirculating isn't a problem if you set it up right, but I'm guessing you don't so recirculate that air. But what is this I hear about a "blow-through" setup? What is that anyways?

 

[icekilla126]

A blow threw setup replaces your stock maf sensor with a gm maf. Place gm maf after your bov and you can vent. It also flows better so it increases performence. To use the gm maf you will also have to buy a translater so your car can read the signal coming from the gm senser. The translator also has small tuning ability so you can upgrade to bigger injectors. Dejon tool makes a great kit. Check out my pics.

Just a quick question that I've though about for a while since we're on the topic of recirculating BOVs. Besides the obvious reasons to recirculate your BOV, does it add a bit of performance when it opens up for a shift since the air goes back into the intake, does that give the turbo a little bit of extra "spool"? It seems to me like this would help keep the turbo spinning for a little bit in between shifts. Just a thought...

 

[icekilla126]

i would assum that only the exhaust has the power to spool the turbo while the air on the intake is only being compressed and creating resistence agaings the turbine. If any thing not having any resistence on the intake side would keep it spooled more. (im only makeing assumtions i could be wrong)
PS: i know my spelling is atroses... it 2:00am right now

I'm not sure, but I think the Beating Dead Horse icon showed up here because of venting.

It's odd that no one has ever asked about it before.
