om648 s211 e320 cdi - merc85 - 01-07-2016

Hi there,

Whats the best route to getting abit more power from the om648 cdi? ive currently only got a stage one map, of no idea of the power as she hasnt been on the roller's.

Ive got a Cat back exhaust coming to help it breath a little better but ideally looking at de-catting the system as there are 2 cats one up top and the other undereath unless this is the wrong thing to do of course??

Would love to get her to 300bhp at the flywheel if this achievable?

Any help really apreciated Smile

A slightly bigger turbo would do or an upgrade of yours with a bigger compressor wheel. The stock intercooler was a problem on the W210's , it's really small and the ECU will cut power once intake temperatures exceed 50 degrees celsius. You'll probably need injector upgrades. Don't know much about this, just some basics.
Also you'll need some gauges or a data logger: EGT's, Boost, Intake temps, etc.
You should read this:

The OM648 you have and the OM613 he has are basically the same engines, injectors,turbo and the EGR valve are supposedly different.

With ref to the Intercooler, i was going to try a w211 e320 v6 cooler as this core is thicker and slightly larger but retains the same diamensions length wise so would be plug n play.

Has anyone done this i wonder??

You need better cooler, little update to turbo and remapping.
~300hp is a peace of cake.

You are a Superstar tuikku , will give those a look

Thankyou for the reply Smile

Does the Compressor wheel swap straight over ok? and is the retaining nut left hand thread?

Ps followed your thread on mbworld with the w203 awesome project!

Will 722.6 hold torque associated with 300PS? Anyways I recommend cleaning intake manifold/valves and removing EGR prior to any tuning.. whats the point of chip tune if intake ports are gunged up with black shit. Angel

They hold up ok with the e55k and that has 700nms, do you think a e320 cdi running 300hp will be more? Good point on the mani Wink

RE: om648 s211 e320 cdi - MartinB - 01-11-2016

But I think in E55 is gearbox stronger.

Nope same box, thats why they didnt put a 7g in there because it couldn't cope at the time

RE: om648 s211 e320 cdi - starynovy - 01-11-2016

Not all 722.6 are born equal.. you can have stronger clutches, TC etc. That gearbox has limit of some 1100Nm according to wikipedia, I doubt they made it so tough even with 220CDI engines.. unnecessary cost for manufacturer, there are various input torque models for sure thats why I ask. Somewhere I read it takes 650Nm long term. And since DI diesel produces power down low you can calculate torque with simple equation. I think it will do at least 600Nm at that HP.

RE: om648 s211 e320 cdi - tuikku - 01-11-2016

Compressor wheel is plug and play.

That 320cdi MB transmission lasts 800nm, I have tried, many times.

W210/W211/W220 320CDI - same 722.626 W 5 A 580
W220 S65(strongest) - 722.649 W 5 A 900

Yes, sorry. W5A1000-AMG is strongest. I have EPC 2008 - maybe this is the problem.

RE: om648 s211 e320 cdi - tuikku - 01-11-2016

.
In the very beginning of boost air hose, between it and turbo, thre is some kind of silencer.
You must remove it, if you some day want +300.
That silencer limits the air and power to ~300hp level.

You need solution like this, or similar.

RE: om648 s211 e320 cdi - MartinB - 01-12-2016

I see, that they are also offering extended tip compressor wheel.

RE: om648 s211 e320 cdi - tuikku - 01-12-2016

Not with orig turbine.
Extended tip wheel is so efficient, that hot side upgrade is needed.

RE: om648 s211 e320 cdi - starynovy - 01-12-2016

I have been looking at that plastic cylinder at turbo outlet many times.. excellent reply tuikku, will remove it. What diameter of air tubing you recommend? Is 63mm enough?

RE: om648 s211 e320 cdi - MartinB - 01-13-2016

In OM611 with this turbo is also extended tip bad choice?

No, if have AMG turbine also fitted
Otherways, Yes. Compressor is too efficient to stock turbine. No benefit, just harm.

RE: om648 s211 e320 cdi - Turbo - 01-14-2016

why not double GTD1752vrk?

RE: om648 s211 e320 cdi - Turbo - 01-18-2016

I would rally like to hear some technician in Borg Warner or Garrett research department to respond to that, I do not trust that sours, it get a little to much they are saying and there is no reference to a research document,

fluid dynamics is a very complicated subject, if you have 15 equations but only 15 variables (navier stokes equations in the turbulent area) they are not easy to solve even if you can simulate it statistic mathematics or use large eddy simulations by CFD simulations, but what do I know...

RE: om648 s211 e320 cdi - merc85 - 01-24-2016

Thought id share a little update, I fitted a cooler from a e320 cdi w211 3.0v6, the car immediatly felt smoother and had more torque, ive also fitted a new cat back Exhaust which has got rid of the pause i used to get 4th -5th.

Here's what it sounds like lol

Its tight but does fit, all hose connections are the same but the core is a lot thicker.

The 722.666 is the beefy one you want to get. I believe it will hold 700+ ft-lb torque. Mercedes used it in the ML-55 and the other performance V8 cars.

Nope if you want really beefy one you should get 722.648 or .649:

Mr Tuikku,
just a small question , the GT23V u were speaking about with AMG turbine , do u happen to know in wich car can i find one ? or do u have the Garret Part number or OEM part number?
BTW how much HP can this baby go? with the 63mm bilet compressor extended tip and dada.
thanks

Sorry my late answer.
The car is W203 C 3,0 cdi AMG
Google finds.
~400hp/1000nm, done many.
