Need Help Installing Boost Gauge

[AusFreak]

Hi,

I got a boost gauge and am having difficulty figuring out where to place the hose.

I know that it goes after the turbo so I tried to place it on the nipple on the intake manifold which ended up making the gauge suck rather than blow into it.

I then found a couple of hoses which i think was where the factory boost gauge was/is. I am not too sure because my instrument panel has been changed and it has no factory boost gauge on it. I put the hose on there and it does work but its not accurate (i think) it only shows 1-2 PSI when i rev it from standing still.

I took a couple of photos, if someone could clue me in that would be superb thanks

First photo is where you want to put it.

Turbos don't make boost free revving

Hi Ben,

 

I put it on the nipple in the first pic but its showing vac rather than boost, its sucking whereas the second pic boosts a bit

[Ben C34]

Trust me. Have you never seen boost gauges that also show vacuum?

You measure the boost in the inlet manifold.

When i rev it the needle maxs the vacuum rather than the boost. It should be going up on the psi and when removing throttle it should show vac, correct?

[Ben C34]

No.

It won't make boost just revving. Take it for a drive.

okay ill give it a go when I get up in 12 hours but  I still recon it shouldnt be vacuuming

Sorry I forgot to ask, in the second picture, what is that for?

Hoses in the second picture are what goes to the factory boost control valve and wastegate.
