    Thumbs up

    Took 15 min and it sounds great! One Question though,... would it sound better w/ an intake?

    I love my TXS RFL BOV. I wouldn't trade it for any other one. Never heard about it running rich though.

    For sound, you will here the turbo spool up more by adding an intake. Have your removed your silencer? That will do it to and it only costs a few minutes of your time. Don't waste your money on an intake. Not worth it.

    everybody be sure to lubricate your bov with engine oil. They don't come lubricated and mine like would not go off unless at super high rpms. I lubricated it and now it is fine. My friends was like this also. His wouldn't go off at all until I lubricated it.

    This is bambooi on johnyero's name. Im at his place.

    intake and bov

    as a newbie, these are the two things i can afford concern most:
    1. intake - i know CAIs aren't useful in the STI, but what about just a regular short RAM from the WRX, seems like no companies made any intakes for the STIs yet, are the ones for the WRX work fine? will it mess up the ECU or AF ratio? since god did his blitz SUS with many other mods, i can't really tell

    2. bov- it's going to sound good, i know the WRX flanges work with the STIs, i know greddy and blitz are the ones we should use since TurboXS and HKS do leak a lot, but besides running rich when shifting gear, what other problems might it cause?

    what do u use to lubricate it? do u lube it from time to time since so much air has gone thru it?

    also by running rich does that mean only shifts or when idles?

    a/f gauge's are usually inacurate unless you have them calibrated for wot. There's some guy you can send them to that modifies a/f gauges to work only within a specific voltage range during wot and makes an A/F gauge way more accurate, otherwise they dont tell you much.

    You can tell its rich by the engine stumbling at idle. And I retract my previous statement, its not just when you shift but actually when the throttle plate is closed. The throttle plate closes though usually between shifts as well though.

    Good questions, These are probably the first 2 Mods I would also like to do. Lets hear some feedback. Would the WRX Short Ram Intake such as AEM be to small in diameter (i.e would it fit?)

    coz we got the intercooler already
    a few degree changes in the intake won't be useful and we need the air quick during spools, and air in cai will take too long, best is just having a foam filter at the inlet, but then there is the sensor, so short ram is the best

    I drew it with Adobe Illustrator 10. I do that kind of thing for a living, I just had to do a ton of research.
