Turbo?
Turbo?
Air recirculation valve. It lowers boost pressure to force more exhaust into the intake.
Replace the air filter housing as well, the 84 has a more narrow airflow path to clear the ARV.
Cool, man the smog nazi's got to this car too. I will keep all my old junk but put the first build together with the '82 stuff, I probably will use the N/A intake on this engine also but the new engine will alot different. They are not fooling around with old Merc's yet but I'm sure if you drive a smoker or there is a tax to be gotten then we will have to adapt ond overcome. That is why I chose to Hot Rod Merc diesels, as of now they are smog exempt here in Califorina.
I was wondering that same thing last week end when I saw that same turbo at junk yard down in Denver
good luck! keep posting pics as you get some progress done!

I saw it two weeks ago at pull and save I think??? 33 & Peoria if not it was pay and pull on Zeno ST. there is a w115 300d up at Anderson's in Greely I saw that 3 weeks ago don't know if its still there

(07-09-2009, 08:35 PM)Telecommbrkr What were/are the smog limitations set by the EPA for our years of Vehicles?Places that do actually check usually have nothing more than a 20% opacity limit. 20% is a lot of smoke and would be hard not to notice. My 300D got 36% before I swapped the injection pump.
Quote:Can we inject water/meth or propane for a cleaner exhaust? Or what about post turbo injection of something into the exhaust system? water or the eurea stuff?Water just cools the combustion. Propane will make the A/F ratio even more rich.
Quote:Gale Banks is a huge proponent for the diesel tuner industry to focus on 'clean tuning'.Thats because most of his products don't do anything but slightly increase airflow.

Doesn't the propane help to burn the last 25/15% of unburnt fuel in the combustion process ineficiency of our diesel engines?
Nope. Its just an extra fuel. All the diesel burns in normal combustion when there is enough air, there isn't 15/25% left to burn.
I'm all for a clean burning diesel and F.I. probably knows how to keep one from blowing too much smoke but I don't think a OM617 that is all turned up is going to conform all the time, I'm going to run with this exempt vehicle for now until they decide to attack the old Merc's.

(07-10-2009, 12:15 AM)Telecommbrkr So, theoretically, as long as you provide enough air you can keep adding fuel till it smokes then back off the fuel, and be a non-smoker with lots of power?Yep. The uni-flow 2-valve head is what really restricts the 617's power. The 606 is usually the choice of the Finns because its 4 valve cross flow head can flow far more air. Even the non-turbo 606 makes as much power as a 617a.
Quote:Why is it then, the diesel drag-racers got these huuuuge turbos and blow black smoke like a coal-fired steam engine? They need bigger turbos? Better fuel management? Correct me if I am wrong but smoke=unburnt fuel right?Poor tuning and trying to show off; To a lot of people lots of black smoke is really cool and you can make lots of power by dumping in lots of fuel. I've seen 800+hp pickups with no smoke at all, so there really isn't a good reason to belch black smoke (except to piss off tailgaters).

Hi,
avoiding excessive smoke in combination with performance gains is my goal.
I have to because of strict emissions regulation in Germany.
My theory is (besides providing more air) to reduce the injection duration by using larger custom elements. But progress in fabrication is very slow at the moment.
I even try to get an individual emission check to jump into a better emission class to help the diesel-benz community here in Germany. But the way is hard and stony.

There is a guy running 300hp out of his 2.0L CDI on MBWorld but he can't make any more natural (no nitrous) power than that because his engine just won't flow any more air. ( http://www.mbworld.org/forums/diesel-for...i-mod.html )

Good work tomnik, let us know what kind of numbers you get when you go for testing.
What pump are you making elements for?

(07-10-2009, 05:34 AM)tomnik 6.5 mm for MW
7.5 mm for M
both are calculated and designed with a weaker control edge to avoid overfueling compared to standard 5.5
Things go slow but still some progress. MW 6.5mm will be first to be ready.

The diesel drag racers roll all the coal for a reason. If you watch even a well tuned cummins or powerstroke you will see them rolling black smoke on the line before they fully stage. At this point they are trying to get the turbo to light. Once the turbo lights you will see the smoke turn to more of a haze.
The other side of the race shop where I work is a complete CNC shop and we prototype many things, if a part does not exist for a project we build it so I was thinking if the elements are hard to come by than I need to get my hands on one and see if we could wip a few out.

I went to a local shop and they told me they could put 8mm elements in the pump, although it has been said they are too big...They are quite expensive $300-$400 each. I found a company in china that makes them, looks to be $3-$5 each, could be a typo.
I just bought an IP and plan on tearing it apart to see what I can do to it. The only issue I see is for myself to machine the grooves, but a competent machine shop could do it on a CNC.

basically it should be possible to burn clean even with increased performance, it is the challenge to get our old diesels cleaner and stronger.
Remember I found after market 8mm MW elements for < 50 EUR/each in the 8mm MW thread. This died when s.o. wanted to get the elements from China.

That is way to much. I found the 8mm in Turkey for ~100 euro each. The chinese companies do no actively make this product, they will want a 1000 count order minimally. If you find other wise let us know! Also the 8mm have a different stroke, did the local shop say anything about that? Did you tell them about the 8mm elements or did they already know?

Personally, I'd rather order the €45 7mm elements from a known source like Myna than risk buying Chinese.
You'll be paying $1000-1300 for a rebuilt injection pump anyways so $1500 for Myna's specialized treatment isn't a bad deal. Most shops won't do just a plunger swap, especially on the M-Pump since the cam has to be removed.
Myna doesn't do MW pumps, just the M.
Except for Tom's custom 6mm elements, the best options right now for an MW are to remove the rack limiter and turn up the torque capsule a little. That will get it about 145hp, but nobody has confirmed that on the dyno yet.
