Boost Gauges

[Stinky Rooster]

Can anyone help with photos or links on how and where to connect a boost gauge?

I want to install one, and I have the fitting to the cabin part all sorted but it has dawned on me, having never owned a turbo charged car before, that I have no idea where to plug the gauge into to get a consistent and accurate reading.

any help will be hugely appreciated.

Well there is a nipple at the back of the plenum you can easily access for a reading.

In the pic below it is where the red circle is, it is on the back, facing the firewall.

There is one on the front too, if you would prefer a longer and brightly coloured vac line running though the engine bay screaming "I'M MODIFIED! I'M MODIFIED!!!" No? Didn't think so...

Mmmmm....nipple *drools*

insert childish giggle here.

Thanks for that.

I just fitted my new boost gauge yesterday, if you wants pics of how i hooked mine up let me know ill post some up

Simon, I would like to see pictures if you can be bothered. Everything else you have done to your car has been very neat so I expect the standard will be high!

That would be awesome!

I was a little cheesed when I realised that no one had stuck something like this in the DIY section before as it is one of the more obvious mods to be undertaken on a stagea you would think, and I am a complete and utter nOOb when it comes to the finer points of turbo ownership.

Its pretty easy ill get some pics tomoz, as im struglling to get my phone to work with the computer at the moment

[FLYSLY]

Have a look in that area and you will find it, should have a little black rubber cover over it. Not hard to find once you know what you are looking for.

Yeah that is not one of my pics, just quickly google image searched for rb25det and got that.

It really is not hadr to find, it's right at the back of the plenum, is the only nipple to come out of the back there, and faces the firewall.

*giggles* I said it again, nipple *giggles*

Here ya go this is where i hooked mine up to, and there is also a pic in there of the nipple Ska was talking about! But i just found it easier to hook it up to where i hooked it up to.

The Last pic, is the pic of the nipple that Ska is talking about

The nipple is the bit that is blocked off with the little rubber cap thing on it, but you will prolly have a vac hose coming off yours

[FLYSLY]

1st Pic: Blue vac hose that goes from plenum chamber to fuel pressure reg. Cut That hose and put T piece connecter in between like i have done. Now conect black rubber thing that comes with boost gauge (only autometre models come with the really small nylon hose) now connect nylon hose into the rubber reducer. Now just run the nylon/vac line as neatly as possible through engine bay using cable ties to stop it from getting caught up in anything that might damage it.

I found it close to impossible to run the vac line through the firewall, so instead i ran it as neatly as possible through a gap in the gaurd then up and under the door seal and then in behind the plastic pillar and into the boost gauge etc...

If there is anything i have mucked up/ missed out just let me know etc...

through the door seal? how about pull the drivers side front undergaurd cover off and theres a big grommet in there to go through feed the line through behind the brake booster etc and through the hole into the gauge.

dale the gauge can be put anywhere using a suitable sized vacuum line that comes off the plenum as long as the hose u choose doesnt have a one way valve in it (brake booster etc) and u will know as the gauge will only ever goto zero and not show + boost

hope it helps

[FLYSLY]

Not through the door seal lol, i dunno its hard to explain and i prolly dont know what its called lol.

Brad's idea for routing is best.

Adjacent to the brake booster you will see a hole that goes into the wheel arch. Remove the front wheel, mud flap and then the few screws holding the inner splash guard in place - just enough to be ablle to see inside and you will see a large rubber grommet where all the wires from the dash come through the firewall.

Poke a guide wire through from the inside then tape on the vac hose and pull it back through to the inside of the cabin. I doubt you'll find an easier place to feed it through.

If your vac line is one of those thin 3mm white plastic varieties then it would be a good idea to thread it into a larger 6mm plastic hose to protect it as they kink easily...also the 6mm hoses come in a variety of pimpolicious colours.

I have my boost controller feeding off the same spot as your boost meter ...so i can't really use that unless i put another T join there...but will look rather awkward...i have my boost meter reading off the nipple at the rear of the plenum just above the AAC....but i find that boost readings is less by about 1-2psi (dyno charts show that my high boost settings is 10psi ...but the boost meter is reading the high boost at slightly less than 0.6 bar...and i know its not a faulty boost meter coz i tested with 3 different meters.

Dale how'd you go?

If you're having troubles, I'm sure Mitchy would lend a hand if you need it.

You coming on Sunday? See you there if you are
