RE: MB 300SD oldtimer - jeemu - 04-15-2010
(04-15-2010, 03:34 PM)Tymbrymi Has anyone done any work with the electronic pumps yet? I think that would make a huge difference in what you dyno graphs would look likeHere is some electronic pump made at 7mm, but those are low emission cars, so those had tune smokeless and not that big turbo, there for no that much power as mechanical pumps can give.
We get new dyno in Kalajoki where i go dyno my car. Then we get double mass on rolls. So turbo spools earlier and dyno graph looks much nicer.
And bt the way.
Sorry JTY your awesome topic goes off topic.
RE: MB 300SD oldtimer - Tymbrymi - 04-15-2010
(04-15-2010, 04:00 PM)antonmies Actually they do these days. If you go and see a newer more emission controlled diesel engine, you will see a wideband sensor in the exhaust manifold and sometimes also after the cat converter.
I was really skeptical about these super rich fuel ratios, etc. since they don't make any sense compared to anything I've read so far, but I remembered that my CDI has a wideband O2 sensor on it!! It can measure a lambda from .7 to 4.0 (10.3:1 to 59:1). The crazy thing is it is mounted almost exactly at the turbo outlet.... so it is exposed to some pretty sooty exhaust. Admittedly, not as sooty as these performance cars, but it is definitely able to withstand "normal" use of a diesel.

It isn't the pump that's limiting power, it is the tune right? You could take one of the electronic pumps, put your elements in it, and tune it to make the HP you are correct?
(04-15-2010, 04:35 PM)jeemu We get new dyno in Kalajoki where i go dyno my car. Then we get double mass on rolls. So turbo spools earlier and dyno graph looks much nicer.
What is the mass of the rollers? Does it match the weight of your car?

Those are low emission cars and those cant put that big turbo as these old piece of shit. Actually those cars cant change at all if goes right at the law says. another thin is money. Electronic pump at 7mm and tuned software cost more than mechanical pump.

(04-15-2010, 07:19 PM)GREASY_BEAST(04-15-2010, 05:28 PM)jeemu Electronic pump at 7mm and tuned software cost more than mechanical pump.
If we can DIY the software, it should cost quite a lot less than a mechanical pump. All the shop has to do is install and balance the elements. Governor is all software, should be able to be tuned with a laptop and a chip programmer.
Still you need some cash to get the pump and new parts + service for it.
Software is not the problem or the controller, not for me.
I usually go with the parts i have and improvise as i go. Still if i were building new a setup i would go directly with CDI engine, skipping om60x engines all together. New MB CDI engines are strong and easy to tune.

Yes VERY cold weather, still waiting for the spring
Been driving with the car some bit, it's been a blast to drive. Still needs some tuning on timing, have tried several settings to get best results.
Currently having problems with one injector and "minor" oil leak. Oilpan got an hit from "speed bump"
When those are fixed it's time to go on dyno.

Has been little busy on work side, but managed to install LSD on the diff last week and made some modification to wastegate side and exhaust.
Here's some youtube video, first is older from April side doing some tuning and second one from yesterday when i tried new modifications on closed road (video stopped too early):

Where did you mount the first inter cooler before the engine rebuild? I just got the exact same one for free and was wondering if I could make it work on my '82 with too much cutting.. I can kind of see it through the top of the bumper but Iwas wondering if you had any more install pics of it?
The one I ave Measures 21.5"L x 2.5"w x 5.5"t

All intercooler installation pics are on first page.
There was no cutting involved, just install brackets for the cooler, it all fits behind front bumper
RE: MB 300SD oldtimer - Captain America - 06-11-2010
Nice. I don't think I could make it fit as nicely as yours though. the SD bumper is definitely tons different than a regular D bumper. Mine looks like it belongs on a tank lol

I've heard these solutions don't last long, will be interested to hear about lognevity. They are what $200 or so USD? I still have no clue how this works.

I'm sure it depends on how much you use it.
Also, the clutches in a normal LSD don't exactly last a really long time either.
RE: MB 300SD oldtimer - JTY - 07-18-2010
Okay some minor updates.
Made an hybrid steering box from 123 worm gear, steering ration now little faster.
Also installed water injection setup last week, made some trial runs yesterday and blew one boost pipe
Seems to work as planned, EGT are way lower and now the rear end has some problems to keep up
Pics coming soon
Also need bigger pump for MOAR fuel!

If it works it works. Paint it with the pipe and it wouldn't look much different than a bung weld.

JB ?
It's threaded to the pipe with some hydralic glue in the threads.
Very secure and will hold
RE: MB 300SD oldtimer - Captain America - 07-22-2010
Ok I see. I was asking because usually those brass fitting are NPT and I just use a little lock tight then wipe off the excess.
RE: MB 300SD oldtimer - willbhere4u - 07-22-2010
(JB weld) It's a glue that hardens like plastic we use it over here in the US

A two-part epoxy to be more specific, I have used similar for some repairs. Many have used for permanent repairs with good results. We use a two part that is a putty that my brother and I call "Magic Booger". You tear a piece off and knead it to a uniform color - smells like ass though
It has some sulfur or something nasty in it but it works!
RE: MB 300SD oldtimer - Captain America - 07-22-2010
I use Locktite #246 to seal all NPT fittings. It is quite fantastic actually, more of a sealer in my book than a thread locker. Plus it is oil resistant! Its a darker blue and thicker than your standard #242 stuff.
Well it still locks the threads.... just not permanently.
RE: MB 300SD oldtimer - JTY - 09-08-2010
Small updates nothing new really.
Have been driving alot, changed to ethanol/water mixture, much better response now.
Also started installing NOS kit.

Brabus suspension from the 80's was spot on, the stance is just perfect for the w126 chassis.
The car is still in everyday drive, same configuration, runs strong and is still fast.

RE: MB 300SD oldtimer - Secondaries - 07-18-2012
How is that fake LSD holding up? If you're using the car much I'd pull the diff cover off and inspect your spider gears. Truth is, that style "LSD" (AKA Phantom Grip, AKA Phantom Slip) is actually a bad and incomplete copy of another, better LSD add-on. There are supposed to be clutches between the sprung plates and spider gears. Instead, those plates wear directly on the spiders to limit slip. Which is bad, m'kay?
Other than that, your car is awesome and you are awesome! Thanks for the inspiration!

Yes i know that, it's not the most optimal solution but currently the best before i can get me an 1st series LSD diff. So it really doesn't matter if it eats the spider gears. I installed the "softer" version of the lock which have finer machining so it will not eat metal so fast but it also holds less.
I'm using performance grade diff oil 90W-145 and that have also made difference, i also change the oil quite frequently and so far there has been minimal metal in the oil.
Thanks, let's keep these oldies in the pace of progression
