    Default VXR GAUGE..What do they do and how do they work!?

    I'm just wondering whether anybody can help me out and explain to me how a Prosport boost gauge actually works and what they do? The link below shows one in action..

    They show boost pressure.

    Do you mean the function of a boost gauge or the needle swipe?

    Yes it is worth getting mate.


    A turbocharged car produces both vacuum and charge air(boost) pressure.

    When they turbo boost pressure in the manifold is low orbit building, the inake manifold will be calculating vacuum.
    All cars produce a vacuum.
    When you put the engine under load the exhaust turbine in the turbo will spin faster due to more exhaust gas being thrown in along with a lot of other things being calculated, which in turn spins the compressor wheel and creates charge air in the intake system.

    This boost pressure is sent through the intake manifold to be ignited in the cylinders, this is why turbocharging is called forced induction the air is forced in more than a na car.

    The purpose of the gauge is to monitor how much vacuum and boost pressure the car is producing at a given point. This aids greatly in tuning, but also to make sure your car is running healthy levels of boost pressure.


    I could go into a lot more detail but hopefully you get the gist of the gauge now?
