look what I got in the mail




now let's see what DPF removal, EGR blocking, GTB2260VKLR & a tuner with experience will get out off this diesel...

This is possibly one of the best small frame vnt turbos currently available! And the only ballbearing vnt at the moment....

Have fun with it, and please take some pictures without the caps ;-)

So.. maybe we should open a new topic:

OM642 + Alternative Fuels: HCCI Combustion

Don't you dare

It's magic

Brake cleaner 1
OM 642 0

Which car did that charger come from? Inducer diameter?
//Nilsson

Inducer is same like other gtb2260vk, 44.5mm IIRC, comes from OM642LS, around 190kW stock

Correct.

Turbo is from latest 350CDI Bluetec engine with 265hp.

If you don't mind, where did you source this from i'm after one for a project on 1.9 GM cdti engine

thanks

It's not exactly plug & play ...

Turbo mount is different

New vs old, new turbo mount has a hole for the watercooling




Water outlet in the turbo



Plugged the bottem water feed an tapped a new one in the turbo mount



Tapped into the block to feed water to the turbo



Blocked the EGR & It fits :

Hi, so I finaly found a place where we can dyno without having any work done to the car.

It was not us but an employee from the place who was doing the pulls.

Out of 8 - 9 pulls we only had 4 good ones.

ESP was fully switched off.

First & 2nd pull, my tune wich I drive now for 30.000 km

Only in the first pull he could give full throttle without downshifting.
The computerscreen was calibrated till 210KW and it flat spotted from 3200 to 4200 rpm, so this would have been the best pull but I don't have a print out.

2nd pull was 205KW/3473RPM & 670NM/2541RPM (second page highest line)

Just a little haze out of the exhaust

Now we loaded standard map, no DPF, no cat (First page)
3th pull was 163KW/3811RPM & 429NM/2919RPM

Now I thought let's make a dyno queen so we added 10% more fuel

4th pull was 200KW/3568RPM & 665NM/2486RPM

Lots of smoke

This is where I was shure that the guy behind the wheel wasn't pushing full throttle.

Anyone know how we can avoid the downshifting?

How do the boost level look like?

1.6 bar only, we need a 4 bar map sensor and find the calibration in the ECU to achieve higher boost levels.

You can see in the original map, the dip in the dyno sheet is because the turbo spools faster then stock, it hits the boost limit & cuts down, then picks up again...

I have one of those turbos w/ very low mileage, has a bad actuator if anyone is interested. 642's and biodiesel don't get along. MB put out a good document about how it really destroys these engines.

Also make sure to correct the open and closed loop boost mappings for achieving good boost control ;-)

austincarnut I would be very interested of the turbo, please pm me if you still is interested in selling it

diesel2fast4u do you have how the boost as function of rev is responding?

If possible and for a good information on this thread, and if anyone knows it, the teorical/real maximum values for:

-Injectors mm^3/hp
-mass air flow rate lb/min
-cylinder heads cfm's
-turbo boost BAR
etc...

I will do some measurements on air flow and injection soon and will post my results. If you have any please post.

Hi guys!
I have a question about mounting GTB2260VKLR on the motor OM642.920.
I know that the flanges are identical as GT2056V. I know about part number A6420961145 - turbo mount, gasket A 6421420681 and A6421420981. I know how make water output from the turbo.
My question is how make the water inlet to the turbo? Just drill a hole as shown gasket A 6421420681 in motor block?
Thanks for your help

Yup--Its the DPF situation that causes most of the incompatability issues with BioDiesel....

Its pretty nice then that the OM.642 imported to the UK market--Doesnt Have that Nasty Device fitted, as far as I'm aware!

Here in the UK, DPF's cause more trouble than anything else on diesel-vehicles! 'Orrible bloody things! There's loads of Co's doing DPF deletes here!

On W211 there should be some "dyno mode" which can be activated over cluster menu.

yes, there is a "secret menu" and there you will find a dyno mode submenu.
