Explain the vacuum boost gauge please

[xris]

Hey guys I'm completely new to the world of turbo 4s and was wondering how I should read the vacuum boost gauge.

Anything I should look out for or keep an eye on?

Thanks!

Needle to the left at idle/light throttle good, needle to the right under throttle good.

Now you're speaking my language SloSnake haha!

I think that 04SloSnake nailed it. It just tells you if the engine is sucking air in or the turbo is blowing air in.

There is probably something more technical going on, but that is pretty much what I have always watched for inside the car.

The boost gauge is how much turbo is being put in the ecoboost. The vacuum gauge is for how much vacuum is in the v8 engine. They don't change the gauge so that on the production line, it is less parts to sort/change therefore there are less mistakes made

Its stupid that it comes with the PP GT. Last time I checked, the GT isnt supercharged / turbocharged lol

At idle and at light throttle his engine will still be in vacuum as well. When your turbo hits it's boost threshold (when your motors exhaust gasses have spun it up enough to make useable power) the needle will swing right and your gauge will read positive boost. Vacuum isn't limited to V8's, all motors will sometimes be in this condition.

OP that needle can be fairly handy for troubleshooting issues with your motor and or turbo. For example, if you are sitting at idle and your Vac is pegged to the left, not moving, you could have a leak somewhere. The same is true if you mash the gas and your car is not hitting its boost target (have no idea what that is on the Eco 'Stang). Under normal conditions, you would honestly just ignore that gauge until something felt wrong.

**Edit**

The gauge is still useful for troubleshooting N/A motors as well, and will definitely come in handy should you choose to supercharge. As an added bonus, it's factory so it won't look tacked on like you will find with a few turbo imports.

The V8 gauge is all vacuum, there is no boost side.
