    GFB....sell it

    I had one and it did the exact same thing. Sometimes it would blow off and sometimes it wouldn't. This pissed me off so much that I wrote to GFB and never heard back from them. I was tired of hearing my stock turbo "giggle" from the bov not opening so I sold it. It just seems that GFBs do this for some reason.

    My 2 cents
    If you can't run fairly from a dig, take your rolls back to the bakery.

    That or if you've got a boost gauge hooked up to it verify that it's reading boost, one of the hoses could have popped off and that could cause the BOV to not work.

    0.2 miles per gallon X 15.9 gallons = 3.18 miles difference

    of course i am only speculating on when the car will run out of gas with the gas light on, but im pretty sure the manual says there is like 2.3 gallons or something like that left in the tank when the light comes on. either way the numbers to me are too small and too close to say that the car is running lean. Technically is it? yes, but its not anywhere near the danger zone.

    just my 2cents

    btw i dont have a blow off valve, and dont want one
    Just for everyone's knowledge, the information posted above is not how cars are tuned, nor is it scientific. Without an AFR and EGT guage, as well as a careful eye monitoring both, it is impossible for someone to say that their car is "fine". Long term engine damage doesn't happen in 5 WOT passes, it's cumulative.

    Calmer than you are
    that's gas light on method is flawed. I've actually had the gas light come on with 1/4 tank left. Wherever the level sensor is its DEFINATELY influenced by the angle of the road you're on, and who knows what else. A more accurate comparison would be to measure the amount of gas put in to the second or third auto shut-off (just to make sure its really is full) rather than assume toat gas light on = 15.9 gallons. its too inconsistent.

    Sound clip of the tial bov

    I was wondering if anybody had a sound clip of the tial bov, I've heard it on supras but not on a wrx, does it sound the same and what are your thoughts on it.

    bov and intake on 05 wrx

    I know these two mods are more for sound then anything else, and in some cases actually hurt performance, but is there an intake and or a bov for a 05 wrx that will not hurt performance without a tune?

    Hack your intake silencer and replace air filter with the K/N drop in filter($40-50 air filter),

    BOVS, stay with stock. You can buy recirculating BOVs but you can either invest it on an uppipe/downpipe combo.

    if you were going to get an intake, at least get an up pipe downpipe first. i would probly get the K&N, or the perrin. stick with short rams.

    my stock bov is actually pretty loud with a up pipe and short ram. i wouldnt waste money on a new bov because mine sounds just as good.
