    Angry which bov is best for me?

    i have an 02 wrx with a top mount intercooler and i cant figure out which bov to buy. it looks like the ones ive seen wouldnt work but not really sure. it looks like they would mount but i see a pipe coming into the stock part and it dosent look like it would connect anywhere. if you have the same set up let me know which bov you bought or which one would be best. (i want it to be loud obviously) thanks!

    Your stock one is the perfect choice for your set up. It's good to about 20psi or so. BOVs that vent 100% to atmosphere are no good for WRXs. I suggest reading the BOV thread & other stickies. You might also want to check out the Unabombers Manifesto. Enjoy.

    EDIT: you already asked this question in the BOV thread. All the info was provided for you there.

    This sentence alone will get you hate responses, you are on the wrong forum if youre looking for a way to make your car louder instead of faster, but if you want any advice, we would need to know more about your set up

    none are best for you, unless you've got a built motor on standalone EMS and speed density.

    I understand your new to this forum. as am i. but even a day into reading anything on this forum you learn 2 things. NO bov's and NO CAI's unless properly tuned for and even then the bov's really aren't good either way. Try reading all the stickies before you start posting or even use the search key. It'll help...serioulsy...or your probably gonna get flamed for asking a question that someone already answered.

    Lightbulb Greddy BOV??

    i just put on a greddy bov without the recirculation kit. i wanted a decent pssst out of it but it sounds like the stock one that u cant hear. i tried adjusting it harder or softer but it still doesn't make any sound. its a type rs kit, is it just normally quiet?

    It's not so much that anyone cares if they wanna be loud, it's the long term effect on a quite expensive component of the car, that the warnings are about.

    Yeah many people have tried to tell him that, but he refuses to listen.

    Take it from me, a new motor is not cheap. As of now, i'm looking at $4K for mine.

    VTA (Venting to the Atmosphere) is bad w/o tuning for it. It will cause you to run lean w/a tune and damage your engine. Either use the greddy bov w/the recirculation kit or go back to stock.

    The stock BPV is good for up to about 20-21PSI.

    You want more spooling sound do the silencer delete.

    When you are idling, driving around, and under boost, the BOV is CLOSED just like stock. The only way to be running rich is if the BOV was somehow letting air out post maf, WHILE RUNNING, constantly. The exception to this would be a valve that is leaking REALLY badly, and in a case like this, you will know there is a problem right away anyway, as the car will probably barely run. For it to leak this badly, it would have to be physically damaged or just REALLY f'd up. However when you shift you do run just slightly rich. First-The rich condition is not THAT rich. On most tunes the target A/F under boost is @11.1-1 or so. Say you are at 11.1-1, then you shift and it vents. It will swing rich, typically to around 9.5-1. That is NOT that rich.

    Have the problem is setting/tuning a BOV is easier said than done.95% of the people that have them do not have any idea how to adjust them.Also there are actual performance benfits to using a recirculating BPV's over BOV's.I don't 100% agree with Davenow's thread on NASIOC.This info just gets reguritated over and over throughout this thread....

    When you copy and paste from another forum please give credit where credit is do. I'm sure Davenow would appreciate it.

    None the less while there might be differing views on the situation it's not worth the headache in the long run IMHO to have a BOV. When the stock setup works wonderfully why risk it just to be the cool kid with a "pssst".

    Donkey post beat mine...none the less...please do post stuff indicating it's yours when you copied and pasted it. Also (not a knock on Dave) consider your source.
