    UPDATE:

    So last week I was able to borrow a friends stock bov (thanks killaho) to do some testing. With the borrowed stock bov, I was able to build up boost slightly quicker, and was also able to hear the audible woosh of pressure released back into the intake circuit, via my velocity stack coming out of my stock air intake box.

    I did come to the conclusion that MY stock bov has a lazy spring now (I probably wore out the spring with too much boost), and leaks air into the intake tract under pressure. Also, after shifting, my stock bov doesn't even give any sound out of the intake tract.

    So I looked around, and purchased the Forge recirculating BOV. I was in a hurried state of confusion, and ordered it without doing any research on it, which is really not like me. I assumed it was a 50/50 bov, but it turns out it is a 100% recirculating bov. Yes I know, it is the same configuration as the stock bov, but my opinions are down at the bottom of the page to explain my choice, which I am pretty happy with. I installed it yesterday, and I have a few opinions on it.

    The Forge recirculating BOV holds pressure a lot better than either stock bov I have tried. From idle to WOT, the car doesn't bog at all like it seemed to before. It also seems as though the motor is much more responsive at different rpm's. For example, I tried going WOT from idle, 2000rpms, 3500rpms, etc, and there was little or no hesitation. And this bov also gives a little more of a woosh out of the intake tract, which is kinda nice. But I have to turn off the radio to hear it. I like hearing the release of the air when I want to hear it, not when it is overbearing and annoyingly out there after every shift. And it also gives a little bling to my Hyperflow TMIC as well.

    Thanks guys for your input on this topic. I really appreciate your posts and comments.

    APS TMIC Blow Off Valve

    I'm curious about this BOV and have a couple questions..

    On APS's site it says..

    "The large primary vent is designed to plumb back to the standard entry point which ensures the best driveability during cruise conditions and cures the problems seen with after market external single venting blow off valves."

    I know BOV's that recirculate cause little to no problems with Sti's, but you dont get that great sound . Is that all APS is saying here? It recircs therefore negates a lot of the problems BOV's the vent the the atmosphere cause?

    If anyone has this BOV please chime in!

    Thanks!

    Removed BOV today

    After about 1200 miles, I removed my Blitz DD BOV today to see if it had any effect (good or bad) on performance. The idle quality and driveability is much better with the factory BOV reinstalled. I won't be putting the Blitz back on. It anyone is interested in giving it a new home, make an offer. I will ship it.

    I have the APS FMIC BOV, car runs A LOT better than when I had the TXS RFL BOV. Car is really smooth. I reccomend APS products.

    Im using the APS BOV too, absolutly no problems, the only difference in driving is the sound, and yes, it still is plenty loud, I acctually wouldnt want it any louder, they seem a bit pricey though, guess I was lucky, got it off Ebay for $100 as soon as the guy posted it

    I ran the APS Dual Vent since I put a boost controller on my WRX. It is hands down the nicest WRX BOV.

    Graham Goode BOV install/vacuum hose loca.?

    Installing the BOV but don't know where to connect the 3ft vacuum hose to. It goes on the BOV but won't fit over the T connector. There were no instructions and I can't see trimming the excess 2 ft of hose off. Is this where it goes? Back on the T splitter, or somewhere else? Anybody have an idea?

    Same with my RFL. I do need a new BOV though, one that works. The stock one is on again but it is not performing up to par. The FMIC stopped the boost creep but the stock BOV is surging the turbo, Not smooth any more when you get off throttle and back on again.
