Ummm....:

1) That's a 3.0L, OM603 engine, stuffed into a red W201 chassis

2) The black W201 has a 3.0L, 24v, OM606 engine!

3) They had to totally remove the AC condenser to make room for the intercooler

4) Note that the boost hit almost 30psi (2 bar) while driving!


In case the link above is 404'd, here's an alternate link:

I wish my OM606 NA could smoke like that

I should pick up a 124 with a 603 and play around.

i wonder what kind of tranny their running on the w201...boy what id do to get that set up in my car

I wonder what ECM they are using? I'd figure one out of a w210. Maybe the computer is retuned with software for that specific setup.

In the video it smokes wayy too much, yielding unburned fuel.

I've always wondered if there was a way to add a turbo to mine without going the full 9 yards like on a stock OM606 Turbo.... Some way to mechanically limit the boost so that it compensates for say the atmospheric vaccuum created from the intake process. Something where I don't need an intercooler or extensive reworking. Keeping the cross-over intake plumbing I have just adding a bend to it to direct the compressed air?

I am new to the world or turbo's and diesels, but does this sound far-fetched? A nice Garret T03 that spools up quickly to give it just a nice pick-up off the line. It's somwhat of a dog from idle but once she revvvv's up she a sleeper

These engines are still mechanically controlled, no electronics.

The secret of these power figures is is huge intercooler and turbo + new elements in the pump to ensure the proper amout of fuel for 425 Hp output.

Otherwise the engines are standard, bearings etc.

Transmission is either reinforced mechanical or automatic.

Super-turbos ( as they are called here in Finland ) in W124 chassis do have aircon as well.

The injection pumps are mechanical but are controlled electronically through the ECM. The fuel quantity is regulated through a fuel quantity actuator. This info is off the w210 Tech CD....

This is how ECM reprogramming by www.SpeedtuningUSA.com is possible...

I don't know if I'd argue with Markku - note his location!! And he's correct, the 606 pump is still largely mechanical. I assume they've deleted the electronic controls, which if similar to the 603, are a luxury - not a necessity. How the heck did they retain air conditioning though? There's no room for the giant intercooler, condenser, radiator, and electric fan...! The 722.3 auto tranny (in the 124 with a 603) was also used in the 500E, E60 AMG, SL600, etc and can take the power if beefed up accordingly.

What I'd like to know is what kind of power gain I can get out of a 603.960 with the STOCK turbo, pump and injectors... just by adding an intercooler and tweaking the full-load fuel delivery, WITHOUT sacrificing fuel economy. I know at least 20% gain is feasible with no major mods, but I don't know how MPG suffers, or how much more gain can be had. Hmmm.


michakaveli - you can't bolt on a turbo to your non-turbo engine. The turbo engines have oil cooled pistons and stronger internals to take the power. Slapping a turbo on would very likely destroy the bottom end in short order, or if not, it would drastically reduce the lifespan of the engine. Much better to swap the whole engine to a 606.96x, or just trade up to a 98/99 model that came stock with the turbo (and then slap a chip in the sucker! )

Hi, you was faster than me in replying.

This is the reason why Super-turbos are made in W201 or W124 chassis and engines with mechanical pump. With proper setup like these guys have made you can get 300% power gain without sacrificing the fuel economy, you do not do racing every day. These cars are also in everyday use, making ~40 000 miles a year. Aircon can be retained as well, however not much space left in W124 front. If these guys are targeting now 500 Hp from 3 litre diesel, aircon is the least of the problems in the project.

Your guess of 20 % is good, increase of engine life by decreasing the cylinder head temperature by intercooling is more essential. Actually this phenomenon is the whole base for Super-turbos.

With later electronic controlled engines you can get + 20-30% boost if the chip is carefully tuned to the car in question, no mass producted chips.

But what I want to know is how much torque is he getting?

Unburnt fuel in a gasser is black smoke. In a diesel its blue-ish white, like burning oil in a gasser. Black smoke in a diesel means he's burning a lot of fuel. Smoke color is pretty much backwards between gassers and diesels.

I remember somebody did a computer model of diesel output power and boost pressure. They got increasing power to 100psi and the computer ran out of power.

Nooo.... in a diesel, blue smoke is still engine oil. Black smoke is unburned fuel (rich) or carbon deposits / soot burning out. White smoke can be either excess fuel (in some conditions, usually at cold start?) but is more often coolant. The black smoke in the video is from excess fuel, or put another way, not enough air, or not cold enough air (need some vehicle speed to get airflow through the intercooler).

Scroll down the page http://www.teamrwd.com/dieselboost/300_24.php and you will see the torque in European Newtonmmetres. After conversion please note: figures are correct, your calculator is not broken.

Unburnt motor oil, and unburnt diesel fuel is blue. Properly burn them both and you won't see anything. Burn too much of it and its black, mostly from soot. Did you ever see a diesel tractor pull? My point was raw fuel coming out of a gasser is black, raw fuel coming out of a diesel is blue. And what vegetable oil looks like I don't know. I also think some of the smoke in the video is burning rubber.
