    the stock bpv isn't sprung hard enough to be used as a bov.

    They make pills for that

    The recirculating hose is the thick one that runs across the engine into the turbo inlet pipe, not that little vacuum hose.

    The stock BPV sounds very good actually as a BOV. I have the AEM standalone EMS and running a map based system I just plug the hose and it goes psht loud!

    The stock BPV is designed to leak a little, so you are making your car run rich.... Thats why it stalls and runs ****ty.

    ummm I find this hard to belive since I was holding 16lbs of boost fairly well with the stock BPV. I dont see why it would be "DESIGNED" to leak, that doesnt make sense.

    You can dent the top in with a hammer if you want it to hold a higher psi, but it would be a PIA to get back out if you dent it too much. You are better off getting a 100% atmo bov or a variable recirc valve (ie 50% recirc 50% atmo). I have the Forge 100% atmo and I have no idle problems and no lag in between shifts.

    edit: btw, you are by far best off with the stock unit in stock configuation, unless you are running higher psi and the stocker can't hold it.

    HKS BOV Help

    Im running cobb stage 1 right now and threw the hks bov on last night. Car ran fine for about 20 minutes, then upgraded to 93 oct stage 1, yes I use 93 octane, and it started missing and I was getting CELs. Tried everything putting it back to stock mode, didn't work. Put the stock bypass valve on and it worked fine. The thing I don't get was I was goin at it for 20 minutes with no problem at all. Why did it all of a sudden do this? Also when I took it off, I heard clicking inside like something was loose? Anyway to fix this.



    BTW - Don't lecture me on BOVs. Thank you.

    They just flashed on and off when it was misfiring and when I used the accessport to scan them nothing came up.

    Worx BOV or Intake?

    I would like to get more sound out of my STi and am debating on a short ram intake or a type of both rec/atm bov like the worx. What would you suggest? How loud are the worx bov's? Has anyone had any experience with the turbosmart dual port? Which one sounds better/louder? Would I get more sound by getting the bov or the intake, let me know.
