You wouldn't notice anything aside from the sound. Unless you have turned up the boost enough that your stock bypass valve is leaking boost, it won't help anything, aside from making a lot of noise.
Plus there's the huge downside of venting to atmosphere (with a BOV) on a car that uses a MAF system, basically the MAF measures air as it comes in and you'd be letting air that has already been metered escape to the atmosphere, causing the direct injection system to inject much more fuel than it needs to, making the car run rich for a little bit during and just after the BOV releases.
I was looking at a youtube video of someone from these forums that installed bov and prototype down pipe the released air that you are talking about looks like it will never re enter the engine the bov is mounted on the side next to the enormous plastic engine cover
As stated you will not see any spike in performance. I have changed my BPV to a BOV due to the fact that the ByPass Vavle might rupture during boost. Kansei is talking about a BOV that vents to atmoshpere. You can also get a BOV that will do the same thing that your BPV is doing which is Recirculate the air back into the engine as I have mine. But that will only change the sound. You will here the BOV operating when you release boost. I personally like this mod but if you don't want to hear it recirc or you don't want be noticed on the street, or if your not boosting the car enough to rupture the BPV then just leave the car stock.
In the youtube video above, that is the BOV I have installed, but as I said I am recirculating. On the vid this demonstrates the sounds of the Vent to Atmosphere.
Their is nothing their that I didn't mention Super except the legality aspect of it. If you want the sound Int3grity to change then get a BOV that recirculates. Cannot vent to atmoshpere until you get a chip to program the ecu.

If you ever want to vent to atmosphere purchase a bov that can be setup on either recirc or v to a (of course v to a is only when you reprogram your ecu with a chip) just in case you want to purchase a chip. The HKS SSQ which I have and is shown on the vid is capable of doing so. But there are others.
So the cx-7 is using a diverter valve instead of a bov? I was wondering if i could use the race vavle from hks, it also recirculates when not driving so it would do the same a ssq, but its a diffrent sound. I have a vw gti running ssq, but if i didn't buy it i wanted to buy the race vavle from hks instead.
Their is no difference in the two except for the psi limits. Yes the SSQ is a looks a little different but does the same thing as the other. If you look at both of them they both can be used on either RECIRC and or V to A.
that was the one I was looking at but now that someone posted the wiki definition I understand what was said about blowing off to the atmosphere. I supposed I read to quick.
some serious performance parts are in due for this car it almost makes it pointless to be a turbo @244 they shouldve slapped a v6 instead of 4cyl turbo. car still needs more power is not that fast other cars smoke my ass
but hey i bought the car because I love the style how it drives but no sports cars crossover here.
lol...its all the excess weight int3grity unless when you mention cars you are talking about suv's. But cars you don't stand chance if they have turbos unless you put some serious money into that beautiful suv.

Thanks for answering my question! i just want to put the race valve instead, because it sounds mean, also lets say they decided to dedicate to make a chip or even turbo that would surpass the limit of the old on ssq which is around 30. I
would be able to handle it anways. I say if your going for it, go for gold haha!!(drunk)

Well in that aspect, the stock turbo I don't thinkn will even reach over 20 psi. With that being said I am pretty sure our mani's will not be able take anything more. Running over 40 psi is quite an experience and requires major modifications to the engine.
Coming from someone with an MSP that is running a Greddy Type-RS V2A and had to relocate my MAF to get the car not to stall, yeah the sound is cool but not worth it. You actually lose performance by not recirculating your air back into the intake tract. By recirculating the air, it helps the turbo spool quicker and more efficiently. Just upgrade your BPV to something like the boostsciences diverter valve or just by a BOV and recirculate it. If you are 100% trying to V2A you can look into the 50/50 valves from Turbosmart. They allow half the air to recirc and half to v2a...
