What did you install to have the 1600bar? High pressure pump and injectores? from which model?
I always thinked about this subject (I also have an c220cdi with 1600 from factory) but the pumps don't have the same aspect, they look very diferent!!

tuikku

.
My car is originally 1600bar.
Cdi-technic changes 06/03.
Motortype OM611->OM646.
There are some differences in technics between these.
It is possible to rise the pressure safely, by changing components, and program.
I don`t want to tell everything, that I know, yet.


Here is a old paper for my car.
So, it is 200cdi with manual transmission.
I cannot remember that day exactly power/torque numbers any more.
Clearly over 200hp, anyway.
ESP was “on”, and I am not a “racing-active” person.
Mercedes is not so light car, and I don’t want to break it.
Yes, blaa,blaa,blaa….


It was something like ~14,5s/152km/h.

6th gear and ~4200rpm is ~250km/h.
I could go little faster, but don’t have enough power.
In this, very latest setup and program, that I have now.
Power is over 190kw 4000rpm-4400rpm.
Engine pulls very easily till 5000rpm.
After 5200rpm fuel spray is zero.

I have my own thread,here.

Hope, that Finnish cramps you at least as much, that English do me.

However, there is lots of information about troubles during this project and how I managed to solve them.
There is also a lot of my writings about mechanics, or “working principals”
Unfortunately, my bad English don’t give me chance to do it here, yet.

My car has been all the time, in “every day use”.
Car is very easy to drive and it is working, like stock one.
Everything else is now working really fine, except that I haven’t reach the “goal”.

tuikku man....

You are crazy!

Just wonderin, what is the redline for a Diesel engine?

Most people said that the diesel engine's redline is around 4500rpm.... but your's can go way higher than that....

Other than that, what software do you use to modify the computer?

tuikku

.
There are no that kind of red line, at all.
The highest available rpm,s depends on diesel burning speed.
With the old, pre-chamber diesels, where fuel vapours in chambers, (so it burns then quicker), highest rpm,s with very efficient spray, are about 7000.
In cdi-diesels, where fuel burns slower, pulling rpm,s after 5000rpm,s, is utopia, without heavy modifications in engine, or additives in fuel, which increases the burning speed.
Otherwise, burning “gets after”.
EGP and –temperature increase very quickly.
First that grills the turbo, second comes the engine itself.

So the highest rpm,s depends on spray, fuel and operating principle.
(Of cource, emission tests are important in stock cars, that is also one reason.)


I don’t understand the software question.

Mika Karala, in turbotec have made all the car software modifications.
I am not capable of that.
He makes, practically all diesel-custom-softwares here.
The tool, that he uses, is Winols.

SuperTurbo

so your car's software is custom made or you buy their computer, and install it on your car?

tuikku

.
In turbotec.
With their tools.
There is a dyno, where the tune actually happens.

Turbotec makes also “common” chiptuning.
Actually, certainly the major part of their tune, is that kind of work.

My cdi have 1350bar...
How you increase this in your cdi?
I am looking to for a new injectors... Those you are talking about can be a good solution... have more info? (price)

gaiex

For what I could notice in your Finland thread about your car, you installed in your car the fly-wheel+clutch of the C270CDI rigth? How it supports the huge 500Nm?
I have a costum made Kevlar clutch and it will go to a max of 500Nm!!!

Other thing, when you installed the intercooler, where did you put the small radiator that was next to the horns?

One last thing, what cat did you used, the 320CDI also?

Thanks, you car is looking good, and a project never seen before at many country's that have the c200CDi

harkgar

Unfortunately true. I think a Carlsson tuning box plus a bigger Finnish intercooler like the one in this thread may be the best ways to go.

To be honest I am pretty contented with the 201 horses and 369 pound foot. The mileage is double that of my old E55.

harkgar

No need for good English-post more photos please. A picture is worth a thousand words.

If that is a daily driver I would like to see a road racer. There are some pretty radical diesel 190-Ds on Youtube.

LOB:
I am not sure, if you need any rail-pressure increasing.
Original AMG-injectors (picture above A612…..) gives 55hv/cyl max, tested many times here.
After couple of day I drive to turbotec and try to make AMG-power plus working.
These injectors framework is ~equal to AMG and nozzles are from Bosio, bigger than original AMG.
I tell you more, when I get more information…. and if they really works well.
I don’t recommend you to increase the rail-pressure at first.
Original AMG,s works pretty fine even with the original 270cdi program, power increases ~20%.
And some chiptuning-company there might even tune more fuel spray-time from program.
Or maybe you can take the “box” off, and send it to turbotec, ask them.
Original turbo is too small with the AMG,s.
Same to exhaust pipe, and cooler, and air intake.
“Bigger than AMG” injectors and/or higher pressure don’t work properly until reprogramming.
My cars original rail-pressure is 1600bar.

Clutch/flywheel works fine, I am very pleased on it.
No extra shaking or noise at all and light to use.
My wife, and children drives it, too.
The bad thing is, that it is quite expensive.
You understand it right, great.
Flywheel and pressure plate are from C/CLK/E/ML 270cdi.
Clutch palate is from (6TON) sprintter-truck.
I have no cat at all, only “skin” .
Exhaust pipe is 3inc with two large mufflers.
In annual inspection here they measures only the “level-of-smoke”.
Last time in my car it was 0,26, and the critical level to turbocars is 3.

All radiators, exept cooler, is still there.
In E-modell, there is a plenty of room, in C-modell you must do some bumber-modification.


These older ones do not interest me so much…
Actually I think, that you cannot see the wildest ones in youtube.
If I have understand right, in the “Herlevi-group” there are at least one ~500kw/900nm.
Or more even more power now, this is not very “fresh news” anymore.


My car.
It is classic-version. 200cdi-man.
I bought it as a new.
Actually, the cheapest version – MB is very expensive here, I cannot afford more.

With the popularity of diesel tuning in Finland I assume the following are true:

1) gasoline and diesel are very dear there compared with North America.
2) emission standards are more common sense and does not change from year to year like the EU and USA (car engines are never clean enough).
3) Finns love their cars.
4) Finns love to drive fast. Very fast.

The Finns fought off the invading Russians in World War Two. You should keep fighting the "climateric change" and "go-go warming" that is so fashionable nowadays.

Peace brother. Burn black diesel.

gaiex

I'm also running with an other MB pressure plate, don't know where it came from, but my clutch guy told me that it was able to keep 700Nm, but my flywheel is the stock one...

I have kevlar clutch (max 500Nm), but I lost a bit of the smoothness I had in Stock setup!!

here is my setup: (up is the new setup, down stock in new parts)

240D 3.0T

How about something like this: http://optionimports.com/se253h-570.html

tuikku

.
“Older type” pressure plates don’t always fit to rotate in “newer type” clutch housing.

Maybe 220cdi,s flywheel can stand nearly 500nm torque, if it doesn’t come too early.
The best area of max torque is ~3000rpm, or upper.
And no peaks in “torque curve”.
Then, technics thanks you.


Friday I was in turbotec.
Unfortunately there is not much to tell about it.
Real “power upgrade” doesn’t come true.
New injectors works fine.
But, if we try to increase the fuel rate (spray), smoke comes right away, and cut the power increase.
This is very frustrating….
We measures AMG power plus injectors also with the lower rail-pressure (1350).
Then they gives the same power, than original AMG with the higher pressure (1600).
So, the reason is not in spray or injectors.

Maybe it is now the lack of air…..
I don’t know anything any more.
Maybe the charger is really too small.
Maybe it needs the compressor wheel, which works better efficiency in higher boost.
Although, EGP is same, or lower than boost all the time now and EGT is ok.
Maybe the amount of air is enough for this power level in this engine, and nothing more.
I am a little “lost” now.

New MB-power

A translation to English here:

Haven't seen any news about the 6 cylinder engine updates. If the four cylinder engine gets 150 kW (this is more than the W210 E320CDI had which was 145kW and the same as the 211.026 had), would be interesting to see a similar improvement on the 6 and 8 cylinder models.

240D 3.0T

It is obsolete right out of the box.

BMW beat them to 100hp/L last year and is already selling their engine to the public.
They devolved their turbo technology from the superior VNT to an expensive and over complicated compound-sequential setup.

gaiex

BMW don't use 4th generation common-rail system, and their engines don't have so many torque like these new CDI ones! CDI engines always had more torque than equivalent BMW and Audi engines, also because of its higher cc.

I had BMW and my company have 20d and 30d engines cars and they are great engines, and when modified they are stunning, but the smoothness and superior torque of CDI engines makes me prefer them!

Does anyone know anything about garret 3063 klv ?
Or vnt charger, which is ~same size ?
How about ford, cummins..... diesels turbos ?
Stock power near 300hp.
Preferably vacuum-controlled.

Diesel Benz

I did not realise earlier that the car was yours from new. Pretty brave to work on one's own baby like this. I wish you luck with what ever enhancements you are planning.

240D 3.0T

How about a GT3571Ve?

tuikku

Yes, I am not very wise.
The first “reprogramming-trip” to turbotec with this car was in the next day I got it.

Gt 3571 is just that size, that I am interested in now.
Turbo have to be new, or “as new”.
I am driving a lot, 40 000km/year, so the car have to be reliable.

Every tips about turbochargers and diesel technics are more than welcome.

VERY big nozzles
Seven holes.




In stock nozzles:
1350bar – six holes
1600bar+AMG – seven holes
But VERY much smaller, actually you need loop, to see them properly.
