    So back on topic...

    I guess the word is that 100% atm on the GFB is not really a good thing? It is loud, but causes problems?
    All show and no go . . .
    Your car looks fast, but why's it so slo.

    hmm this might change my mind from getting the TXS one since people have had problems with it. Nice touch at the end

    Sounds good...is this the 100% atmospheric version, or am I on crack in thinking that they make a 50/50 one?

    Well, try it at 100% atm. and see what you think. If you don't like it change it back. That's the cool thing about the GFB, you can go both ways. I know a few people running full atm. bov and they absolutely love them and the way they run. The WRX just wasn't made to run a full atm. bov unless modified. I won't hurt the car but will slow it down a bit.

    I bought one used, and run it 50/50. No problems, I wasn't looking for huge sound effects though, sounds just right. Cars runs great too.

    Oil residue on BOV

    A friend of mine was wondering what causes a little bit of oil residue on the blow off valve. Is it something he needs to be concerned about? I didn't know the answer for sure so I decided to ask everyone else?

    It is normal. Blowby gasses from the crankcase are vented back into the intake stream the gasses contain oil residue that can build up leaving some gunk. Just clean it up or get a catch can to stop it from happening.

    BOV question

    I'm currently stock waiting for the warranty to end, so this gives me time to think about what I want to do, Iv'e read in a few threads that Bov decreases the engine performance when the turbo is stock, why is that ? My understanding was that the bOV opened to let air into the turbo when you're not on the throttle to keep the turbo spooling.

    While we're on the subject what's a everyday turbo , that I don't have to worry about detonating my motor with? Responses greatly appreciated.

    - thanks

    Some cars behave oddly with an aftermarket BOV, others seem to run fine. Most people will say you don't need to get one unless you go above 17-18 psi.
