Boost line on 4.2 turbo GU

[Lewy]

Gday all,

I have been reading about where to install my boost gauge line and reckon I have it worked out but was just hoping for someone to confirm it for me. I gather that if I attach my boost gauge line into a T piece in the little black pipe coming from the back of the turbo actuator that my boost gauge will work fine from there. Is this correct? I have added a pic of the line.

Cheers Steve

O well Im about to go put it in there now So will see what happens.. If anyone has any ideas don't be scared to post them

I tapped mine onto the cross over pipe of the turbo that usually goes to the aneroid/boost compensator but mine was TD42 N/A so I dont have aneroids on mine so I tapped it in there....Tony's suggestion!

Personally I would rather keep the boost line away from the turbo but hopefully someone can advise otherwise.

A better spot would be to drill and tap into the elbow on top of the inlet manifold. Easy DIY job, 4 bolts, take the elbow off, drill and tap...

See what other's say first....

Is yours intercooled?

I would recommend installing the boost gauge fitting after the intercooler if it is as this will give you a more accurate boost reading.

Gday Guys,

Yes it is intercooled.. I have just put it in where I said and it dose work but will be going out and getting a tap and die set to put it in after the intrecooler...

You can cut into your boost line in your intercooler really simply mate. while you are there you can remove the butterfly gate in your intercooler. I will try and take a pic for you.

That pic you have is actually where you would place your Variable Boost Controller actually but i am not sure how it would go as a boost measure point?

I'll try and get or find a pic for you mate.

Cheers MR

note also the square box in the foreground of that pic, open that up and remove the butterfly while your there.

Easy as.

[Lewy]

Wow that would be a lot easier LOL So what dose removing this butterfly do?

P.S thanks for the pic that helps heaps.... I have fitted it to where I took that pic and it works well but if thats where the boost control gose then Ill have to move it as thats getting done soon :-)

yep you dont have to cut into that alloy part but put a 'T' into the rubber hose going to that point and you should be right. Easy As mate.

The butterfly is part of the EGR on the TD42Ti and will retard the airflow going into your intercooler when the EGR engages. (I think??) Rip her out mate, she's in the way ;)

[Lewy]

Yep done it and it works well :-) So If I just take out the butterfly Will that stop it from using burnt gasses and will then only breath fresh cool air??

Cheers for all your help MR

[Lewy]

Ok I have now removed the butterfly... So now if I put somthing in to block of this (Please see pic) then thats it it will no longer use burnt gasses??

Lewy

[MudRunnerTD]

exactly right. either cut a piece of flat plate or pm Ferret as he make the blanks ad he will send one over to you for a small charge.

[Lewy]

Wicked Mate all done!!! Inlet blocked off, intercooler flushed out and butterfly removed....

Thanks for all your help MR :-)

OOPPPSSS reply to wrong thread


Many thanks to all involved. I have similar noise coming from my variable boost controller. Any suggestions on what could be done to enclose controller to reduce noise yet still let air escape?
I have just wrapped a bit of rag around it with a cable tie to go for short run to test and it definately reduced the noise but need something more fire resistant and permanent.
