I know this is mentioned over and over, but I haven't been able to find an actual explanation as to the pros/cons between venting your BOV to atmo vs recirculating it. Can someone please explain this for me?

ok, if you vent using a stock AFM, or similar your going to loose metered air.... By loosing metered air you will hit rich spikes inbetween shifts and will have possible stalling at really inconvenient times.
The only way to vent the right was is use a basic maf setup as blow though with the AFM AFTER the bov. Or run speed density using MAFT Pro, a VPC or standalone.
Thanks! And I did search first, but like I said, I wasn't able to find an explanation. That's why I asked.
To add onto what x87SUPRA87x said, if you recirculate a BOV, you'll lose less power between shifts because the air is being sent back into the intake pipe.
Only real "advantage" as I understand it is a vented BOV is louder.

How difficult is it to recirculate an aftermarket BOV? I know the stocker will only last for so long, and once you turn up the boost you're pretty much guaranteed to need a new one.
I don't know if there is really that much substantial power you would be "saving" by not venting. But if you are wanting to recirculate an aftermarket bov most of them sell attachment fittings, or some are made so you can do either.Neodeuccio;1444223 said:
