Exhaust Manifold Pressure gauge install

[HDIkyle]

What setups do people use for this? Is a boost gauge ideal? And am I right in thinking it just wants to be between the head and turbo anywhere along the manifold? Was thinking a welded on Nut kinda thing?

[zx_volcane]

Needs to be at least 60psi, I use a boost gauge, but any pressure gauge will do

[mr_fish]

Brake pipe fitting into the manfold is what I done, then just run a bit of copper pipe to get the line away from the heat.

[HDIkyle]

What gauge do you use? Got an oil pressure gauge but its electric sensor would that work?

[Piggy]

no I dont think that would work tbh.

Anywhere in the manifold between head and turbo.

I too used a brake fitting, then coil brake pipe into a piece of high temp tube onto a oil pressure gauge (one that plumbs in)

Needs to be up to 4bar. You'll find boost gauges that go that high are very expensive, my oil/water plumbing pressure gauge was about £8

pretty sure thats something like what i'm using.

ask Sam (barker) what he done, I thought he was using one of though pressure sensors but I'm not 100%

I just welded a brake line fitting in to the system and ran brake pipe up to the gauge works a treat

Im Just using a stock pressure gauge 
   

You can just about see how I have done it .

Got these spare if there any use

Maybe a silly question but how come you put the coils in the pipe?

Helps cool the gas before entering the silicon / rubber hose etc...

Ah cheers, knew there would be a good reason behind it

I'm using a Tim mechanical oil pressure gauge (100psi)

I drilled and tapped the egr port blank on my manifold to 1/8npt then have ran a cheap braided air line off a paintball gun which then connects to the plastic pressure gauge feed pipe once it's cooled down a bit

also allows for flexi/movement I find

Surely the rubber hose etc would do that no!?!

Mine doesnt go rubber till its inside (theres a joke there I think!)

Anyone give me a rundown on typical advantages of monitoring EMP. And what is bad/good/ideal/normal emp level for the xud. I.e is there an optimun pressure to attempt to maintain by altering fuel?

high EMPs can have pretty nasty consequences for the head... your project/budget.

My limited knowledge of things, I would think the most need for upgrading the more modern efficient turbos, or running compound etc where boost is coming in early...

You need to be monitoring spikes in EMP and ensuring its not going ballistic at low rpm when you dont need boost or only have a small amount requested. 

Cruising EMPs are also important to keep doing...IE cruising on the motorway/dual carriageway. 

They are also very useful when setting up... EMPs arent all bad...you NEED manifold pressure to make boost! It's ensuring you don't have a damaging inbalance between the two or high EMPs when you don't need/want boost.




That was a lot of waffle... but maybe Ruan will come along and slap us with his...wet...sciencey...brain.

I was told that you don't want EMP of more than twice your inlet manifold pressure. EMP is important when setting up VNT blowers.

yeah thats a pretty decent start

[mr_fish]

As dum dum says try to run on a 2:1 ratio.

Though I've pinned my 60psi gauge a few times before.
