Boost Gauge Instalation Guide

[JasonW]

Evening all

Firstly, sorry if this is in the wrong section (which i imagine it probably is) and mods you can move it if you wish, but im stil trying to get used to your forum layout!

Now, is there a Boost gauge instalation guide somewhere on the forum? I tried the search with little success so thought i would ask the experts. I notice there are also so many different types of gauges, do they all do the same thing i guess? If it makes a difference it would be for an 03 blobeye.

Thanks

The main types are mechanical and electrical (defi etc).

Mechanical is the most common and cheapest solution, fitting is pretty easy too.

There not all the exact same but here is a guide for the most common type.

The back of the gauge will probably have 3 wires. One will be an earth, the second will go to a switched live and the third will go to a dash light. The first two will light the gage up when you start the car, the one that goes to a dash light is optional and if used will dim the gauge light so it's not too bright for night time driving. Thats lighting it taken care of the next bit is to get it reading the correct boost pressure.

On the back of the gague will be a nipple that a vacumm hose should go onto. Feed the other end into the engine bay and tee it in with one of the hoses comming off of the inlet manifold.

Job done.

SO it really is as simples as that? Hardest part sounds like taking the dash and surrounding bits off. Cheers and i shall now look to purchasing one and having a go at installing it!

Am i alright with just a boost gauge or should I get Oil Telp and Oil Pressure as well as they seem like the 3 most comon ones.

[colin_ross]

That one is really down to personal preference.

Oil temp is useful if you intend to go on the track or drive the car particularly hard as it will warn if the oil is getting too hot. The pressure gauge is really there to tell you if you're engine is in good health or not. The car already has an oil pressure gauge (the oil light) but by the time it comes on your engine will probably be toast already, a pressure gauge might give you enough warning to prevent damage.

I have all three (plus a few more) but have always said I'd like to start removing some of them once I stop changing the spec of the car and know it's running sweet.

I got the Prosport boost/oil temp/oil pressure gauges from Xyberautos for about £90 odd.

Free postage from Singapore. Don't be put off by the Far East. Easy enough to install (obviously not by me!!)

and work fine.

Might not be as accurate(?) as Defis but I only really wanted them because I like the look of them and didn't

want to just have an oil temp on it's own.

Here they are (not my car) and you can get different pods

[Phil MC]

As previously said, there's many different makes, sizes and types of layout for you to consider.

I'm not too keen on having the large triple pod on top of the dash, or some pillar mounted pods obscuring your view.

I've got a pair of smaller Racetech gauges (Boost and dual Oil Temp/Pressure) neatly mounted inside my dash clock moulding.

Just another option for you to consider

lovely and warm if it was zero

Cheers for all the info guys, i really like the look of those prosprt ones but not sure if i want them in the dash.

The visibilty of the ones that phil mc has up looks spot o as well so i guess il just have to see what i like best.

Ive also seen a few in the drivers air vent, is this a good place? look really tidy there but i guess you need the right size one.

Off to ebay for a look i go!

Evening all, just wanting to check that this is the tube that I need to tap into to install a boost gauge? And its also there that I need to put the 'T' piece about 8-10 cms along that tube right? Is it worth replacing the tube at the same time with some new silicone tubing? maybe go for some colour coding while im there or will it just wreck it? I know its probably as obvious as daylight to you all but I am learning!! (albeit slowly)
