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.

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?

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!

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 ..

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.

Under water you mean . ?

I don't think it will be agreat idea .. at least not to me. Even with the positive pressure that you got in the sistem.

Hey Rick.. thanx for your concern I'm on a small summerholiday visiting my mom and my sister down south in the country..
I cleaned the floor before i laid out the parts so they wouldn't get any dirt on them

I have added a pyrometer to my parts-pile... now i only need a few details.. I'll be home and ready for turbo-converting in about 10 days....man! I can't wait...

Doing some rust-repairs on the beast while I'm down here..there were more than a few holes in the roof along the rain-gutter..it has been patched up before..not very well.. I'll post some pics when my girl comes down here with the charger for the camera!

Oh... and here is a picture of me..Incase you wonder what a modern viking looks like...
I'm sorry that i hadn't shaved for the ocasion

I don't drive in water.. atleast not deeper than the top of the wheel... Stuffing the frame with mud and getting dirty water on the floor-carpets isn't quite my thing..

As for the BOV it will sit higher or at the same height as the intake anyway.. so the BOV would be the least of the problems...
No plans for a snorkel..

How much fuel does it use? Does it smoke a lot? Do you know the condition of your injectors? I don't think you really need backpreassure..

Actually not .. you doon't need backpressure in a turboed engine. Which it's your measure of much fuel ?

10 days vacation is a long time, ya?

It's Ok, I am going on a vacation also, so I will watch you build your turbo system from coffee shops and internet cafe's!

Skol!

Hey! That looks like a real good and usable increase in power and tourque... But one thing strikes me, 35kW ?! and 56kW with turbo?

I though it had around 100 hp or 75kW without the turbo

Somebody please explain!
I understand that this has been measured on the wheels, but is 50% of the power lost in the drivetrain?
Will this testresult also vary with wheel-diameter?

Roller dynos are very sensitive to tyre size, pressure and tread, 50% is high but not unheard of.
Hub pack dynos take the tyres out of the equation, but they aren't as common.

Wheel diameter will change the gearing, but the power curve should come out similar. I say should because it'd be hard to change the wheel diameter without changing the tyre tread and that will have an impact too.

OK ! Here we go... I'll start the work tomorrow

I will be using the watercooling for the turbo and i was wondering, could i remove the return-pipe from the heater that runs along the top of the engine and use that "loop"?

It would be a very clean way of sorting the pipes..+ give improved access to the injectors etc.

I could go from the red arrow,, get rid of pipe with orange arrow and hook back in at the yellow..

Whatchya think?

Well... I decided to take the water from the drain-plug on the block.. and return it to the rediator-hose.

I have started work !
Got rid of the old exhaust and stripped the front end from it's batteries and radiator..
Drained oil and coolant
Battery-trays have been cleaned and painted.
Cleaned the inner-wells
test-flipped the manifold ends up further back than i expected.
Made holes for IC-tubes
Removed oil-preassure switch, drain-plug and push-rod cover to prepare them for modifications


Oh.. and i attached a picture of my storage-thingy

just looking at the first pic and was thinking how do you guy run your zost off the turbo with all the brake booster and steering there?

I wondered about that too.. I will have to move the turbo forward about 15 cm with the adapter form the manifold.. then the exhaust will clear the brake stuff... steering is no problem, it will pass the steering-parts in the same place as the original.
But yeah.. a RHD would be easier
