Turbo for 2H (1 Viewer)

[marting]

Hey Bigluxs! That looks good, I see you have left your manifold in it's place.. i will flip mine around.. fabrication of adapters have started.
But I'm not sure it's the same turbo..(infact after searching for turboes for a couple of weeks I'm now convinced there aren't two alike in the world) Accorcing to "dougal" mine is a T25G
And yours is a T03 ?
They look really similar though..

What did you do with the hose from the fuelpump to the inlet on the intake manifold?

And what did you do with the engine-breathing pipe (from valve-cover to intake)?

I'm very interested in seeing some more pictures of your plumbing

He's got the T3/T4 that we were talking about on the other page. If you click the little arrow next to your name in the quote, it takes you to the post he quoted from.

Aaaahh I see.. hehe ... Yeah i guess that is the one i should have too.. But I'll go with the one i bought now..maybe it works great?! If it turns out to be hopeless the seller will get me something else..

I still wanna see your plumbing though..if anyone can give me links to other plumbing-pics it will be much abliged.

Doug! Any idea on what boost the non-adjustable wastegate on my turbo is set at? I'm guessing 8 psi ? whatyathink?

That'd by my guess to.

For example .. my CT26 non adjustable wastegate, it's set to 10 PSI .. after that it start the opening and you will see the overboost light in the das ..

But it's pretty easy solve it if you want more boost ( BTW disconected wastegate, means more than 20 PSI of boost ) with a boost controller ..

Halmans Manual Boost Controler .. ( don't waste money in those turbonetics boost controllers )

 

[marting]

Hmm.. I see... So if one uses a boost-controller, one can "move" the opening-preassure on the wastegate upwards? I mean can i keep the wastegate as it is and then use a B.-C. to give me more or less boost?

Curious about some plumbing..

There is a nipple on the compressor-housing and on the wastegate (dont know the name.. the part that holds the spring)
These two should just be connected with a hose right?
And if i use a boost-c. it sits between those?

And as i mentioned, what about the hose from the "throttle-body" to the IP What does it do? Is it vacuum from the intake that regulates the fuel-flow?
Can i move it from the intake to somewhere before the turbo on the air-intake.. I'm guessing it will be about the same?

I also wonder what are the best places to take/return water to ensure a good flow that doesnt stop or change direction under any condition..

The oil will go from t-piece behind the oil-pressure swicth

Also the turbo is pretty heavy. Have you guys used any supporting brackets to hold it, or does it only hang from the manifold?

The pop-off
(wich I guess is overkill for my application, but it sounds cool)
It goes on the intake-tube right before the intake right? where does the hose, that there is a nipple for on top of it, go?

One more thing.. I keep calling them "hoses" is that correct? or would "line" or "pipe" be more correct.. I'm thinking a pipe is something made from a hard material... like a plumber would use
and a hose is soft made from rubber etc..Maybe tube is a better word? Are hoses for gardeners and firefighters?
I think I have a pretty good english vocabulary for a Nordmann..But there are some "holes" in the technical departement

You guys (especially you Dougal) have been very helpfull....
I think I'll have to ship some delicious Norwegian beer to all corners of the earth when this is "over"...as a token of my apreciation.

Happy to help, but I thought the Norwegian climate would be more suited to spirits.

For boost control I prefer to cut the wastegate rod and weld in a threaded section (be careful not to overheat and burn the seals). This lets me change the boost from almost zero to the maximum the turbo can produce (wastegate always closed) with just a 10mm spanner.
It has the advantage that it holds the wastegate closed tighter than a boost controller so it doesn't open by itself.

This is what my T25 looked like two years ago. You'll notice the plugs in the side, I don't use the water cooling.

 

[Tapage]

The Manual BC are a great option for us with a non adjustable internal wastegate and also don't want to cut and weld anything in our setup .. actually it function and are pretty accurate the setup .. you can set it to 14.5 PSI if you want .. at least mine.

The MBC go between the turbo compresor housing and the wastegate itself .. in my case halmans MBC block the pressure that normaly goes throught the hose from the compresor to the wastegate to activate it ( means start bleeding exhaust pressure in the turbine side to control your capabilities to build boost ) ..

Blocking this " signal " your wastegate keep closet alowing you ( your engine ) build more boost until the wastegate start open due to your settings ..

The MBC allow you to " lie " to your wastegate building more boost ( even with the risk to go over your surge line or sure out of your eficiente island in the compresor map ) but it don't affect the process to build boost sooner or later ..

If you run a turbo IP then you have ( in the case of 1HD-T IP ) at the top of the IP a boost compensator. The hose that you mention from the trotle body ( in the 1HD-T in the cross over pipe ) brings the " boost " signal from the intake to the boost compensator, that add more fuel ass is needed by the engine ..

More boost = more fuel ..

You can mode this hose but always need to be after the turbo .. means where you have positive pressure.

Hmmm.. are you sure about this... I am running the original pump
As it is now the tube will give vacuum to the pump, (I'm guessing there is a vacuum right before the intake) not preassure!

Shouldt this go where there is negative preassure?

A guy in NLCK told me i could just plug the holes and remove the tube... He has a setup with some t-pieces and tubes going everywhere... and it doesnt work proparly.. he has trouble driving at an even speed..

Let me clear on that ..

1. Vaccum is vacc and boos it pressure ..

2. In a NA engine there is no boost compensator

3. In my 2H throtle body I have vaccum when the butterfly it's close ( inder it sure ) that's why and how I run my BOV there.

Most of the factoru turbo diesel engine no run butterfly at the throtle body.

 

[marting]

It's still not clear to me.

I am aware of the stuff you listed as 1 and 2 some of part 3 i don't quite get. But i know it's unusual with a butterfly. Is the butterfly the reason for this tube?

i guess it's obvious that there is a vacuum in the hose when the butterfly closes because it comes out after the butterfly.
But, there is a small pipe to let air through at idle..to small for higher rpm's, hence the vacuum as the engine revs down..
But when adding a turbo and boost I'm not convinced there will be much of a vacuum even with the butterfly closed..
If I move it to somewhere after the turbo like you said maybe i can just leave it as it is? is that what you are saying tapage? have you got some pictures of your setup?

What does the vacuum actually do to the pump?

 

[marting]

Hang on... The tube is connected to the throttlebody before/over the butterfly.. I think this means it has to go somewhere with a constant negative preassure, like between the air-filter and turbo!

 

[Tapage]

Let's see .. here is my BOV ( little muddy ) and the vac hose from behind of my TB that goes to the back of my IP ..

Here you will see where I get this hose intercepted to get vacc signal for my BOV

At idle your turbo are virtually idling also with no boost at the intake. close buterfly and little vacum at the bottom part under the buterfly ..

 

[marting]

Interresting!.. so you have done nothing to the front hose, and put a t-piece on the rear one and hooked this up the BOV....

So when you step off the gas and the vacuum under the butterfly will "assist" the building preassure in the intake-pipe to open the BOV?

How does this affect the original function of the mechanism in the pump?

It's obvious that your car works though... Muddy in Panama?

When you leavy the skiny pedal the butterfly close and create a vaccum under it that activate the BOV .. I was little worried about the amount of vacc that need the BOV to open .. due to the little vac that create the diesel engine .. but was enought to activate ir.

How does this affect the original function of the mechanism in the pump?

All it's working like always .. ( with much more fuel ! )

Muddy .. down gere .. 8 months of rain !

Looks like fun on the youtube videos.
