    The sound you're hearing when you get on the gas is a combo of air being sucked and the turbo spinning.

    Cold air intakes (CAI) are known to make the turbo sound more audible as well as the BOV sound.

    I got the CAI from Fast WRX.com and they never put a number on HP increase. They only said don't drive in high water or you could hydro-lock the motor. Thanks for the advice.

    BOV do help if you have a large turbine. You can alslo change spring rate to compensate for boost pressure.

    You bought it from them. What they said was true(about hydrolock) . Do a search for CAI and read it from people who aren't selling it to you.
    P.S> I'm not trying to be an ass. I used to have a CAI until I learned about the negatives about it.

    I crushed one for a customer at the track once. It worked well and allowed him to hold a little more boost to redline.

    It was cheap and effective, although there comes a point where the stock bypass valve isn't going to flow enough for high-pressure applications.

    When in doubt, add more boost!

    It doesn't "help," it allows you to do it. When you get bigger wheels you have to get bigger tires. If you increase your boost enough, you need to get bov to support it.
