Made this modification to my 84' after watching this video and the engine performance is significantly better. I now have accurate throttle response and the car accelerates well at higher speeds (over 70 mph). Thank you for the tip and for the w123 series!
I was just watching a video I made of a 1971 Torino Squire wagon, with a 429 Super Cobra Jet engine and a shaker hood scoop. Holley double pumper carburetor, with a build sheet and the window sticker, all original paint, what an unbelievable rare rare gas-guzzling American excessive car. And then you send a video of turbo boost on little Mercedes diesel. What a difference from one world to the other
The world of cars and those who appreciate the different types is vast. I think that there is appreciation for cars with lots of power and those that are really efficient. I have had both. This old Mercedes with the OM617 is really cool. Those engines were built to last and get reasonably good fuel economy. I always got in the mid 20s mpg when I had mine. The cars to are very rebuildable too which adds to their panache.
Auctiongram Malik I drove a similar chassis 15 or 20 years ago, I thought it was the most uncomfortable School Bus steering wheel underpowered POS, but like everything, times change and my feelings have too. Now I have a whole bunch of Mercedes, but newer chassis, and no diesels, but that will change I hope soon enough
Hello i have the 1987 300d turbo diesel om603. I deleted the egr on my car And a couple people have said i should remove the air flow meter and unplug it saying it will run better. Isnt that connected to the electric vacuum switches that control alda and other components. They said it is only to control egr. I trust your judgment above others. What would you do. I like keeping my car as close to original as possible. Everything is original except the egr to stop soot build up in intake manifold and i run dual electric fans instead of original because it stays cooler with ac running on 100 degree days. Thank you for your time and videos.
I watched the video, hooked up the two lines in a bypass and took a ride. Zip-Zoom went the Mercedes. Much better performance. You can bypass permanently or do it as a diagnostic. I will now research which direction i want to go in the end. Thanks for the video it helped a bunch.
I am purchasing my first W126 very soon with the 617. Am I correct in saying that what you just did there was to bypass the electronically controlled vacuum switch which controls enrichment and simply connected it straight to full intake vacuum? This appears to be analogous to connecting full intake vacuum (in a gasoline engine) to the distributor vacuum advance mechanism providing better spark advance.
Hi I just bought a 300SD and the engine has seen better days so I was thinking about rebuilding it and was thinking of turning it into more of a performance car. I was curious how much horsepower could I max out while keeping it reliable and safe. With all performance parts going into the engine what would be a reasonable amount of power? I am trying to get around 300-400 hp out of the engine and wanted to know if that was possible?
I deleted my Alda, it was leaking internally and I had extremely POOR engine performance. The Alda kit cost $28, a used Alda was over $350 , it was a no brainer
Ugh. I hate it when people butcher cars like this. It works fine the way the factory designed it. Have you even adjusted the valves yet? That's usually the biggest performance enhancement on an old neglected OM617. What about the fuel filters?
gotham61 Yeah, I'm not a bag fan of modifications. You probably can't improve much on the German engineers who designed it. I love getting original equipment working again. It would also be useful to viewers on how to get the Overboost Protection Circuit working again.
It's a pet peeve of mine. A guy working in a garage thinking that he can outsmart dozens of the best automotive engineers in the world who spent years developing something. You may tell yourself today that you're never going to overstress the engine, but that changes at the moment when you're trying to merge onto an interstate with an 18 wheeler bearing down on you in the right lane.
Ah but what's good for the engine may not be what the EPA requires. We all know that EGR in diesel is a disaster. MY 1991 OM602 was a tarry mess when I finally opened it all up.
Nicely done, thanks.

Awesome! I just bought an '85. My first diesel! A dream come true. I've watched a couple of your vids so far. You make it easy to understand. Thanks!

I have a lot of vacuum system work to do. Thank you for your videos. :)
Is it dangerous to run line from vaccum pump to Wastegate directly
Very good knowledgeable video

Great Video😀 keep them coming. That OM617 are really cool. I've always been curious to see if they could get more power out of them.
me too...now we have a chance to try
HELLO. JERRY
THANKS FOR THE VIDEOS
very helpful 😎😎😎
you are welcome

Dude you are a legend
I will watch later...

Thanks
you also would love to disconnect/remove/plug up the lines going to EGR and ARV :)
that is all going in parts bins in future videos
yes sir! i would love me to delete the EGR on mine and also take apart air intake to clean up the gunk inside it! Good video ideas right here :)))
This dude's intro every time creeps me the fuck out am I the only one?
You must confront your attraction to men
great
Your camera light is dim please show again with high light thanks
thanks !

Why not just remove it and delete it
1st!
Nice
