    What kind of spring releases the valve at a low pressure, then it doesn't at a medium pressure, then it does again at a high pressure???

    2003 Blaze Yellow WRX?!?!? Ummm...

    Anyway, good to know. Basically it's not the best idea to get a 100% atmosphere BOV on a stock or close to stock WRX.

    I didn't say it didn't release it. I said I couldn't HEAR it. The way air is released determines what kind of sound it makes. It's like the difference between bleeding air out of a balloon, breathing, and opening a bottle of champagne.

    So in other words, your BOV is releasing the pressure way too early. The purpose of a BOV is to release built up pressure which could potential prevent the turbo from staying spooled up during shifts. If it releases at 2000-3000 rpm's, and the turbo isn't even fully spooled, how is that proper operation of the BOV?

    I thought all of Forge's BOV's are 100% atm. (at least for WRX's).

    Does anybody have the Forge recirculating BOV on their car? Would it have the "woosh" sound or does it sound quiet like the stock BOV?

    Exactly. You'll end up with a BIG vacume leak because the stock BOV is open at times when an atmospheric bov would be closed.

    If you want the bov sound from a stock bov, remove the resonator. It's crystal clear that way (although makes no power; some [myself included] have found it to slow you down).

    Well you seem to know everything so why don't you tell me?

    Cars are just like people. Although there are many similarities, they're ALL DIFFERENT. Stop complaining, I'm not trying to start a fight with you. I like the sound, I get better throttle response, and I really couldn't care less how yours works.

    In other words, leave you the F alone? You got it.

    Stop, I could have been much less polite. But why are we arguing over something so trivial?

    I dunno who's arguing, but since you'd like to perpetuate this discussion, I might as well mention one more thing...

    You said that cars are like people and are all different - not when they have the same BOV!

    We don't have ALL the same mods. I actually hear mine LESS with my DP... besides, we might have different models of the hybrid. I have the older one with the blanking cap. Is yours adjustable? If it is tell me what you think about it, I might change to that.

    I have the older one with the blanking cap, and that can only be 50/50 or 100%, depending on whether or not you connect the recirc hose. It's set at 50/50, and I have a cat-less down-pipe.

    Resonator? The only two things that come to mind is the exhaust resonator and the airbox silencer. Is this something different?
