Welcome to another episode of Mighty Mods

Now today we're going to show you how to install a boost gauge in a turbo car

Why are we going to do that, Martin?

It's a good idea to keep an eye on what your turbo's doing, uhm, a gauge is the perfect way, you can diagnose problems really fast and you can see what's going on and it's just cool!

Yeah yeah, it's cool! it's cool!

and, and, and if you want, you can put them in a non turbo car too

No dude...


They won't do anything

Except if you wanted to, you could physically put one in there

and then maybe you could put a tube under the seat attached to a pump

and as you accelerate you turn the pump on and it looks like the gauge is moving

Let's get to it dude...this is silly


Right, so these are all the tools you'll need. We've got a socket set to get to everything

We've got some wiring, it's actually recycled, left over from our first episode, with the little red Daihatsu and the central locking.

We've got the gauge itself

And we've got a cup, that will hold the gauge and mount it up on the dashboard, out of the way

Not every turbo setup's the same, so you'll need to find out exactly which vacuum line is right for the gauge on your car

Now there are two types of boost gauges that you can buy. One's a mechanical, and one's an electrical

We've bought a mechanical one, which means there's a vacuum line running from the engine bay, into the cabin and into the gauge

Our car had an existing power wire going through to the cabin for the amp

This makes getting the vacuum hose in, much easier

Make sure it doesn't kink, or rub anywhere on the car

Next up, cut or extend the vacuum line in the engine bay and connect the supplied T-Piece

The gauges usually run from the middle of the T, and have a restricter to smooth out the operation of the needle

Now every car's different as to where to run the vacuum line from

With this particular car, the GTi-R, we had to run a special vacuum lead from the quad throttle bodies

Check out our other video if you want to see how to do that

It's a good idea to use hose clamps on most connections. You want them to withstand the test of time

Some hoses will need to be heated up to get them over the barbed fittings

Using hot water will soften the plastic hose without damaging it

Run the vacuum line through the dash, up to a suitable spot

Make sure it's not going to rub on the foot pedals or wiring underneath the dash

Best way to figure out which wire is which, is with a multimeter

We need to find one that only comes on when the ignition is switched on

You don't want your gauge running all the time

Make sure you do good soldering on the connections to ensure they last

The gauge will come with instructions telling you which wires to solder

We made a new hole in the back of the gauge cup to run the vacuum line

The gauge is installed up on the dash, everything's screwed back together, and we're all done

OK, so the boost gauge is in, and how excited are we, Marty?

It goes whaant whaant wench wench

It's a gauge


Maaaant Maaaant
