I own a 1983 300SD turbo diesel. My favorite car! I love the sound of my old diesel! I have over 300,000 miles and still get 23 mpg! A definite tank rock solid car!

[@buksidicsak2281]

In the '70s when mercedes launched the 617 turbo, some trial versions already made 180+hp on the running pad. To keep engine's life long, they reduced to 125hp then became available on the market.

[@joebotelho248]

@benz merc those extra 60hp are at the top end, where you don't spend most of the time

I would like to see the owners reaction from his or hers first testdrive with double the power.

[@Stale_Mahoney]

@Curtis Maverick damn it must be regional or something because it did not work for me

[@kermitefrog64]

Great information. I have a 1981 Mercedes 240d with the 4 speed manual rather than the 5 speed manual commonly found in Europe. The 4 cylinder diesel does not put out a lot of power but I keep up with traffic okay and I have taken many trips to the San Diego area from north of Bakersfield about an hour. It takes about 7 hours after you fight through the Los Angeles traffic. It is always the struggle between lowering the RPM on the top end and having zip on the bottom end. The first 2 gears I am usually right with the traffic but by the 3 gear the car drags behind the traffic until I get back to the flow of traffic.

[@kermitefrog64]

Something I did modify was having the 205 70r14 Michelin tires but now I can't find them at Costco. I also added another air scoop close to my AC condenser. A drunk hit my first Mercedes and totaled it but it makes a good parts car. I took the air scoop added a PVC Y and channeled both air scoops into the engine. I have never put it on a dynamometer but it has made the diesel just a bit perkier. I also add Cetane and Marvel's Mystery oil to the fuel. That helps lower the loud chatter of the engine while getting more power out of the engine. My next big project will be to replace the mechanical radiator fan with an electric fan to take back some of the horse power lost on moving the mechanical fan. I upgraded the alternator to a bigger alternator that took the same plug in. That has also helped. It would be nice to put a turbo on that engine but it was not designed to take a turbo so that idea has been nixed.

[@MiikeyLawless]

@@kermitefrog64 How is it over the grape vine? No problems with those inclines? I imagine the turbo helps with elevation change.

[@kermitefrog64]

@@MiikeyLawless Actually, the 240d 4 speed manual does not have a turbo. I get a good run up the hill and then have to shift into 3rd but it stays around 55 mph. which really pushes the engine. I currently put on a new set of tires and went with the Uniroyal 205 75r14 and it makes a nice difference on the top end and drops the RPM. It makes a bit of change on the speedometer but the added comfort makes a nice difference. My recent project has been replacing the mechanical radiator fan and replaced it with a Flex-a-lite electric fan. I am no longer taking the long trips down to San Diego since my wife died from cancer 2 1/2 years ago.

[@thomasrose6962]

i like the fact that it has very little smoke but cmon gents something has to give here ...double the power means double the heat i have to wonder how the ex valves are doing after a 1000 miles nevermind that the exhaust is going to be twice as hot during extra boost but all in decent work gotta love those Bosch pumps i used to play with quanity adjustment on the rabbits in the early 80's and i got nice results

[@henryrollins9177]

If they double the power they will probably reduce lifespan by half...or less..😀😀😀

[@gregdavies6842]

The majority of road driving uses less than half throttle.

[@Diesel8290]

It’ll only be double the heat if the engine is ran to rich and there is loads of smoke. If the boost is set right and there is no smoke on boost. The engine will be fine. Not to mention there tough as nails anyway.

[@RoofRack2]

I had a 79 motorhome normally aspirated OM616. Drove it to the South of France from London. I was in first gear on some of the hills on the motorway. Then drove it over Pyrenees and the oil light came on. I topped it up but the damage was done. I used about twenty litres of oil getting home - was surprised the police didn't stop me at times. No one could see.

From the factory, the 3.0L turbo diesel made 110 hp @ 4500 rpm.

[@catfish_lude]

Iknow but with a stt turbo kit only 56hp! WHAAAT

[@dposcuro]

@@catfish_lude they are reading the power at the wheels. Manufacturers rate the engine, itself, at the crankshaft. Also, I am not sure if Mercedes did this, but I know American car manufacturers, back until the later 70s or 80s, basically tested just the engine, with no accessories bolted up. No cooling fan, no power steering pump, no alternator.

[@catfish_lude]

@@dposcuro Whaat

[@dposcuro]

@@catfish_lude okay, gimme a second, dumbing myself down a bit here: Factory spec if engine alone. No transmission, no final drive and their inherant losses. These guys are using a chassis dyno, which measures power at the wheels. This take into account the power used to drive the transmission and differential. It is always going to give you lower power figures than an engine dyno. If you say what, one more time, I will get out the crayons, so don't eat them.

[@gaspdahl1]

OM 617.912 = 88 hp OM 617.952 = 125 hp

[@Mercmad]

I wonder why I never noticed this before? I have 300D W123 with a STT turbo on it ,it's not slow (2 actual speeding tickets...) but it lacks real power because of the low fuel delivery setting. I have the STT manual which has a few hints on how to adjust the rack settings etc. I dont have the intercooler either which I think STT said came from a Saab, and the proper STT aircleaner is a large Volvo panel filter. So on hot days here there is a noticeable power loss.

[@ethanwark8414]

How big of a pump can you go for and still daily it without it blowing

[@JoeHeine]

So is there any loss in fuel efficiency with the new pump? Or is it just better overall?

[@camillosteuss]

There may be no loss, you may even gain some efficiency via turbo doing its job better, but your fuel usage will increase either way, as you are actively pumping more fuel... To reduce fuel consumption and to increase fuel efficiency are not the same thing... You can have the best, most fuel efficient engine and induction system but drive like a moron and have poor fuel mileage, and you can have an engine that has poor fuel efficiency(not power necessarily) and drive it with good fuel mileage... Power of the engine, its fuel conversion efficiency and fuel usage are related, but not strictly linked... Either can change without impacting others, and any change in any of them can impact all others in some cases... I cant say in this case does the fuel efficiency of the system rise, but i can say with certainty that fuel usage does rise, and as was shown, so does the power... Now it can be calculated, if we were told all the data and could establish formulas for original setup and its efficiency and then compare it to what we see here, but not enough data is given, and sure, it could be fetched and gathered, but im not here to provide both the resources for math, the math and info, i hope this did help, altho untimely, but whatchugonnado?

[@justcarcrazy]

Neither the fuel supply nor the turbo if so equipped was ever the constraint to power on the OM617. It was always the valve timing. There is a 26° or so period at TDC where both the intake valve and exhaust valve are closed - no overlap, no scavenging. Compare this to the later OM602/OM603 which has overlap.

[@reallyhappenings5597]

Are custom camshafts available to address that?

That car was brand new when I passed my driving test! My BMW f30 320d makes about 185 BHP.

[@Bouzoukiellas]

I would try to get a Turbo engine and do this conversion on. There is a reason why Mercedes upgraded the oil coolers, sprayers, pistons, etc on the turbo models. But if that guy doesn’t care. Oh well.

[@Bouzoukiellas]

Sideshow 44 I have no clue when it will go boom. It might go tomorrow. It might go in 5 years. But one thing is for certain. It will not last as long as one of the US spec Turbo models.

[@Mercmad]

I have one of those STT kits on my 300D. 1985. 130,000 miles and still runs like new. The only thing that kills the OM 617 is rockapes who abuse them,lack of maintenance mainly. And the turbo is the same as the factory fitted to the turbo version. Without doing any pump mods I even got a speeding ticket last year.

[@reesesboot]

been done by the finns. om617a stock internals seem to throw connecting rods around 250hp. om606 is your guy for big power.

[@JFinnerud]

We had the same engine in a G-Wagen with after marked turbo kit turning out around 150 HP. It ran close to 600.000km (372822 miles) before it cracked a piston. Quite strong engines in my opinion.

[@joeb578]

Its actually been done a good bit, but its not the best diesel for a Jeep swap (pmus you're ruining a Mercedes) theyre higher revving diesels more designed for highway cruising at higher speeds, not as much low end torgue for crawling over stumps etc. There's way better diesels for that purpose that will give you more torque at lower rpms. I would really check out the new Cummins R2.8 crate motor.

[@Ellfyn]

@john Parrish buy a Cummins R2.8 or get a 4bt Cummins

[@c.i.m.1600]

@@joeb578 If not sufficient, how about considering om606 turbo, that has been modified. I would think with let's say, just an example 350hp and the right final drive ratio. Just my opinion, I would think that would be sufficient. Though with cj5, length might be an issue ? I'm honestly not that familiar with how much room they have under the bonnet.

[@jastern949]

1- Although I am "state-side", as a W123 OM617 owner I keep coming back to this video once a year and dreaming of adding such a pump to my own girl (372k miles / 599km). Any idea where to get them these days in the US? 2- With good headphones, I can definitely hear the difference with new pump. This engine sounds much more like a truck now. Deeper, more guttural. Cummins? Kenworth? :-) 3- As of the date of my comment here, this video is 5-1/2 years old. Would love an update on how this car is doing nowadays with this setup. 4- BTW as an A/V guy I vote for your getting a) a headset mic (right next to your mouth) for much better voice clarity and background noise removal b) a head-cam (so you have both hands free -- there /can't/ be that many "left-handed mechanics" on YT :P ) , and c) a 2nd cameraman (or tripod) facing you, and then merge the two feeds in post. 5- Love your intelligence and your accent! :-) Wish we Yanks had kept at least one of those when we left.. ;-) 6- Fun channel.

I have a feeling the previous owner turned my injection pump up, mine black smokes on acceleration and idle it’s rich as hell

[@DieselPumpUK]

R B. You cannot change the mixture of a diesel at idle. The amount of diesel injected determines the rpm, if you injected more than the required amount then the rpm would simply raise. If you have smoke at idle you could have a timing or other engine issue. Big elements or nozzles can sometimes give some hazing also.

[@rb.867]

What he says at around 12:13 is "..and obviously this STT turbo kit is similar to the turbo kit you'd get on a normal 617. So you'd be able to expect similar sorts of gains on a turbo 617 by adding one of these pumps." I /think/ he is implying that this car was not originally a turbo.
