    Is it necessary to have a boost gauge?

    Hello,

    I have an 06 WRX and this is my first turbo car.

    I was wondering if it's necessary to have a boost gauge? If things aren't boosting right, can you tell without a gauge?

    Thank you.

    IMHO it's not needed on a stock car, but it's a very good idea. You should notice a power loss if you were having major boost issues, but a BG would be a good tool to have for minor advance warnings. The 06 only runs like 11 psi so if you are running wastegate pressure (7ish) then you might not notice it power wise for a bit.

    With that being said my 06 doesnt have a BG.

    Is it 100% necessary? No, if it was all turbo cars would be required by law to have them.

    Is it a good idea? Yes, a Boost gauge allows you to monitor your turbos ability to compress air, AND it impress the HS girls and the kids at the local parking lot meet (then again so does a huge auto-meter Tac w/ shift light yo!.)

    Can you figure out problems w/o it? Maybe, but it is a lot easier to notice a problem by loooking at a gauge and saying, wait that is WAY too much boost, or wtf why is it so low at WOT?

    I have the stock unit, it is good, just not pretty. Get the Maddad Clarity ones, they look like the $800 Defi gauges, black out and match the lighting/interior.

    If you plan on modding your car at all you absolutely need one. Otherwise, you're putting your engine at risk.

    i 2nd that. stock you can get away with not having one cause its not really necessary, but if you even do as little as cobb stage 1 you need the gauge.

    Robert,

    What kind of gauge do you have and how much did you pay for the whole set up?

    Maddad makes good products. Ive never heard a complaint. I think the V2 ones are even more advanced. NASIOC has a lot of info on them.

    They are priced well, much better than how much the stock boost guage costs.

    Does anyone think the dealership would have a problem installing that?

    If you get an AP, can't you just do a live boost reading from time to time on the AP itself and save the BG?

    You've spent 20k on a car, probaly atleast another 1-2 grands in mod. Now why wouldnt you want to splurge the 150 for a good boost gauge to monitor it?

    I have the factory gauge which costs too much, but it already had it. It's an easy DIY installation though.

    It's kind of apples and oranges. The boost reading in the AP isn't a gauge. It's not very convenient as that cable runs between your legs. I guess you could velcro the AP to your dash, but it'd be pretty hard to read. Get a boost gauge...

    They wouldn't have a problem installing it. You might have a problem paying for it as they'd expext at least a digit if not some sort of future payment of yet to be born children.
