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

[@kvadrupel]

@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.

[@jdantigua1999]

Great videos and I wish you were near Albany, New York. I am curious if this engines upgrade includes an Intercooler?

[@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?

[@danmackintosh6325]

Nice, i like the old school diesels. These old Mercs & PSA XUD are 2 of my favourites, do you guys do common rail stuff too though? We've got a Volvo S80 D5 (euro3 163) and a 206 1.4HDi currently, the Volvo is decent enough but i'd be interested in any tips you might have for getting a little more from the pug, though TBF i think the standard turbo is the limitation as it's running out of puff at the top end. That and no intercooler is a problem (It's pretty standard, running gutted cat/disabled EGR & wastegate adjustment's maxed out).

[@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.

[@hubalahu]

How did it only make 82 hp with the turbo already

Curious about rpm data…the 5.5 pump hp and torque data is recordeed below 4000 rpm. The new pump data for hp and torque is around 4500 rpm. This would make a difference in data numbers, correct? So is the dyno data accurate? Also, how is the engine hp calculated? Is it strictly mathematical? Not actual physical data? Thanks! Nice video looking forward to adding a new pump. Tim

[@DieselPumpUK]

The dyno calculates the drivetrain loss, if an engine makes more Hp regardless of what rpm it is in fact more hp

[@christophermarshall5765]

Nice!!.

[@JoeHeine]

how does just changing the pump make so much more power? Do they tune other aspects? Is efficiency lost? Thanks in advance

[@Stale_Mahoney]

well imagine you have 10g of tnt you get poff now imagine you got 20g ot tnt now you got POFF the engine was originally without a turbo so the stock pump was already strung out and not able to give the fuel needed to drive the turbo properly, now with a pump serving more fuel you have a bather combustion pushing the turbo faster hence making more bost as unlike petrol cars i dont belive this has any boost limiter so more spool is more air and more poff

[@JoeHeine]

@@Stale_Mahoney This is a great answer. So the pump itself was designed for a non-turbo predecessor engine; and thus not optimized.

[@Stale_Mahoney]

@@JoeHeine yeah that would be the basics of it all, as you from factory need to comply with emissions and such, but a pump able to deliver more fuel is bether for power

How can the engine power be so low? A stock 617 without turbo should be 88 hp and stock OM617A with turbo should be about 120 hp

[@DieselPumpUK]

Robin. T the factory claims are miles off, we generally get 40bhp for n/a om602, 55-60bhp for n/a 617 and 55-65 for n/a om603. I’ve tested on a couple of different dynos also. I think Mercedes may have been a bit naughty with the power claims. If you don’t believe that they are that low, ask anyone that’s ever driven a n/a diesel Mercedes, if of sane mind they will confirm how slow they are.

Hi Luke Very impressive what you are doing with diesel engines. I'd love the opportunity to quote you on machining some of you conversion components. Thomfield engineering Ltd. We are a small company in South Wales. Any opportunities would be very much appreciated

[@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?

@@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.

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.
