Whack!!! wtf
Our cars measure the amount of air coming in and add the appropriate amount of gas (tuning tweaks these numbers). The BOV exists in the system AFTER the MAF determines the amount of air that went into the system. That means, if excess air is vented out into the atmosphere rather than recirculated back into the system, the computer will have no idea how much gas it needs to feed into the system.

Its bad for your car because the air has already been 'meetered' or measured to mix with the fuel that is now being delivered to the combustion chamber based on the calculations the maf/map sensors have determined. If you 'vent to atmosphere' on the way to the combustion, you now have less air density than the car thinks it has and it will now stumble. To much fuel and not enough air to burn it.
If you do a little search in the threads (there are plenty) you will get piles of info probably better than I can explain.
The one you have now, like the original 'recirculates' the excess pressure from the system created when you take your foot off the pedal so as not to stall or slow down the turbo and possibly damage it either (under high boost/heat conditions) Venting or recirculating it back to the system allows the turbo to keep spinning and will reduce the ' lag time ' when you get back on the throttle!! yay for boost!
cheers, and pssstt!! all the way home if you like!!!
to the OP: its a shame you are being kinda harrassed the way you are, but in reality, it could have been avoided by much searching through these forums in regards to the ralliart/bov situation.
since i know it can be a pain to do so, though, heres the basics. any valve that you put on the car should be recirculated, whether from an evo or aftermarket or whatever, dont worry about why, there are many details i could give, but its not worth my typing it all out, just know that it shouldnt be done. now, once you've changed out the plastic valve, for performance/aesthetic reasons, there may be an increase in noise, but remember that all of the intercooler/intake hoses are just that: hoses. which means rubber, which means insulated, which means sound dampening, as most people with modifications have learned, the more metal piping (intake, i/c piping, etc.) you put on the car, the louder the turbo sounds are, including spool, recirc, yada yada.
you have said you are going with an intake and an exhaust along with a tune. thats a great start for anyone on here, and assuming you are telling the truth, congratulations. i think once you have those mods, you will appreciate the car that much more, and you will be able to hear the noises you are looking for much better. dont be upset by people who knock your opinion of what you like over the internet, because it is your car and your choice. whatever makes you happy is great, just be aware that others will have different opinions on whats cool or worth doing and they like to vocalize their opinions, thats why we have these forums, just for that specific reason. just learn as much as you can from those willing to lend their time and take the negative criticism with a grain of salt, cause if you dont want to hear an opinion you dont like, dont ask questions, just use the search function and you'll usually find what you're looking for eventually

Lol same bro, and yeah I would help but it seems like you already got your question answered, and yeah prepare for flamage when you don't search. It is a bit ricer to hope for VTA noise but hey, whatever floats your boat... Or RA for that matter. Happy Tuning!

yeah i wasn't 100% concentrated on getting the noise. I was just looking for a small sound I have seen a few videos with the AMS kit and I could here a sweet wooshing sound so thats what I was expecting when I installed mine. but I knew a recirculating bov would be best for my car. I wasn't so clear as to why this was true but now I know. I'm going to make an attempt at installing my intake. maybe I'll take some pics.
Hey mate if you want vroom vroom pshht you need to install a Short Ram, throw your car in Neutral and then Rev Rev Let Go!
or trade in for an used SRT-4 haha... I bet they'll all have pssssst under the hood!

oki found this bov by turbosmart...its a dualport so yu can vent to atmosphere and get the air 2 recirculate. i think that gives you best of both worlds so yu get the "pssssh" and arent harming your car
