I am a marine mechanic and I specialized in Detroit diesel and I feel lucky because I got to rebuild a pair of 2471 Detroit’s at 1,800HP. They were DDEC IIII. They had four blowers down the middle and four water cooled turbos right on top of the blowers amazing engines. The pair of engines also held 65 gallons of SAE 40 weight oil each and 100 gallons of coolant each. Just wanted to share I really enjoy your channel.
What were they in? I am also a marine mechanic and I have done an "In Hull" overhaul of 2 DD 12v71's that were in a 90' Broward Yacht. My Favorite DD is the 8v92.

Detroit Diesel's weren't the best diesel ever built, but they were greatest engine ever built. The flexibility of application to any platform has no equal.
I personally ran a 6V92 for 24 years straight as a oil delivery truck. So it was all short haul. When I bought it it had 300000 miles so I had it rebuilt then ran it 24 years. The hours meter quit at 18,000 and I ran it for years after that. It was backed by a Allison 750 which was a wonderful transmission. It just got too old to keep using it. The cab wiring was going and the leaks were getting worse, so I bought a Volvo with a series 60. I still have that truck. I love detroits.
I swapped out 2 8V71’s in a commercial crab boat. Those things were bulletproof. They ran from the 60’s until last summer, and they were still going strong! The EPA is forcing them out of use because of emissions. Greetings from Seattle
71 series are the best sounding. Especially the 6V-71. I'm not sure why they sound so much better other than maybe the cylinder size just hits a sweet spot for the sound.
Our old school bus had one of those in it. The old Crowns. The big tandem axle crown bus that I usually rode had an 8V71. I love the exhaust note of a Detroit. Nothing like it.
Growing up, that cackle was part of life. All the fire apparatus had 6V-71 mills. Thanks for bringing back memories. Also, your enthusiasm for the material as well as the research behind it is infectious. Thanks for these!

Where I grew up, all the city buses were the GM's with the Detroit's. Those buses fully loaded still managed to make up all the steep hills.. They were screaming!! Love that sound!!! Its been said that USA was build by Detroit's!! Thanks Visio for the great video!!! Keep up the excellent work!! Chow!
The Euclid construction machinery powered by Detroit Diesels (both owned by GM at one time) were largely involved in the construction of the USA's Interstate Highway System beginning in the 1950s.
The loudest, most intimidating Detroit is a 6V53 on the stand with the intake silencer removed. A friend of mine invited me to a shop to see the governor being set by the head mechanic. That engine was absolutely screaming, and the volume? I felt it more than heard it.
I drove a GMC truck with a "238" Detroit Diesel WE called it a "Screaming Jimmy" 10 speed Road Ranger, it was the fastest to get there empty , and by far the slowest to get there loaded... loved that Truck...empty you could shift gears as fast as your hand and arm could move...
2-Stroke DD...The most efficient way to convert diesel fuel to noise, without the side effect of torque...(They made great Horsepower, but pull them 500rpm below peak HP and they fall on their face.)
@@misters2837 Hahaha. You’re right about that. My uncle had a 238hp 6-71 backed by a 5 + 4. It would detect grades you couldn’t see with the naked eye 😂.
@@dieseldemon8562 Its amazing, if you had the right Gear to keep it on the governor up the grade...you were fine...as soon as you got pulled off the governor, they would bog, and if your tried to lug it, as if it could be done, (especially a 92 series) you were rewarded with cracked liners...
People from the logging industry will likely remember the 353 the most as timberjack used them extensively in their smaller skidders from 60's onwards. So the story goes that in Canada up in the hills if you got lost while logging you could listen closely enough and hear a 353 no matter where you were and you followed the sound to safety. In Australia the little timberjacks are almost legend to the older cutters as screaming jimmies.
@@dcrog69 A 4-53 High Speed engine can be heard in the next county. ;-) I live about 3 miles from a couple of pump stations that run N14 Cummins and Cat engines. As I worked at them, I can tell when they are running just by stepping out on the porch.
most people around here still use 353's, 453's and 653's in skidders and knucklebooms. No other engine can take the abuse of running wide open all day in cold temps
I had a mate that drove an 8V92ta in a coach that did 100ks an hour up a mountain gradient an old lady on departure said to him she's never experienced anything like it. It was dry as a bone. He also drove a White Road Commander 2 with same model engine hauling a quad float with dolly 220 000 lbs gross and left 2 444 Cummins powered trucks for dead on the highway and they were towing flatbeds nowhere near the weight of old mates truck. Cheers from Australia.
The 6L-71 was used in almost every US made landing craft in WW2, it was extremely tough, extremely reliable (it had to be when used in a boat that came under a lot of gunfire), put out good horsepower and had great torque and had good fuel consumption (it could go a long ways on not that much fuel). It was also used in a lot of motor yachts and was turbo-charged to phenomenal outputs, almost 500 hp for the 6-71s, and would hold together. The V-16's were called "sweet 16's" for their output, reliability and smooth running. They also had a long production life which probably ended with environmental concerns, being 2-stroke they were a little difficult to make clean running, although they were economical and ran "lean".
The company I work for still has a handful of trucks with 8v92Ts. Absolute monsters. We had one blow apart on the interstate, and was still able to pull the 40,000lbs of weight behind it for 150 miles with a hole in the side of it.
"Most" but NOT all of the earlier Ingersoll-Rand drilling rigs I worked with were equipped with 12V71 Detroit Diesels. This video definitely brings back memories.
Detroit diesels are the most incredible diesel engines you'll ever see or hear, and are even better in real life. The amount of power they can make is truly INSANE
12V71 Twin turbo military engine could produce 600 HP. For 24 hours straight. Then it was overhaul time according to the military. A 12V71 NA engine could produce 340 HP for more that 14,000 hours without problems.
Greetings from Oz! Love your work! Back in the day, (30+ years ago) I spent a lot of time on 8V71's. When we were doing a governor set, one of us (2 man job) would have to sit on the blower housing to make adjustments. Sitting on an 8-71 blower with the motor running flat out without a muffler is an experience I'll never forget. I saw one run away once. The sound was amazing! They got it shut down before it blew up, fortunately. My other memory, not so good, was 2 full days of scraping off gaskets & washing parts prior to assembling the engine.
We have a Cummins whose name I don't know for backup generators. It sounds okay and as a quad-turbo 50.3L V-16 it's awesome in its own right, but I really hope to see and hear a Detroit some time in my life
Detroits have been with me my whole life .6-71 in marine diesel school. V-16-149TI 1KW gensets in fleet, then 3-53's in many skidders in the PNW, and 4-53's in excavators, Bobcats, and compactors in construction, to this day.
When I was growing up and I helped my dad who was a mechanic on Detroit Diesels I fell in love with the sound of those engines! They were a masterpiece!
When I worked in the bush, before retiring, as a mechanic, working on the haul trucks and setting the racks on the 12/71’s got to be a noisy affair. Loved to hear them when running good.
the 12 and up cylinder counts sound so wierd and amazing at the same time. i love them. that v24 sounds like a runaway v12 or 8 yet that's just from the absurd number of cylinders
I worked on and with, a lot of Detroits over the years, mostly 71's, but a few 92's and 149's - mostly in marine applications - both generators and main propulsion, I always respected them, they would tolerate a level of abuse that was difficult to comprehend... but I never loved them. They were all loud and dirty engines, but definitely tough and reliable.
@@brianfronius4166 yes and no. The 2 stroke Detroit’s have been out of production since the 90’s, most ended in 1995. The current engines are all evolutions of the 60 series 4 stroke DDEC computer controlled design that came out in 1987. Also GM sold Detroit diesel to Roger Penske who then sold it to Daimler AG so it’s not a GM division anymore.
@@J.R.in_WV , thanks my friend. The 2 strokes are a dream and marvel. I had a time with one in early and mid 80’s. Beyond sweet. Just don’t see or hear them anymore on road. It baffles me why they’re just not out there anymore. I appreciate you explaining it me. You strike me as a mechanic as well. If so, resurrect what you can and get ‘em back on the road again.
Hello again Visio! Over my 40+ years as a truck driver, I’ve driven my share of Two Stroke Detroit’s! T most recent was only about 10 years ago in an older GMC Car carrier. That was a 3/71, with a turbo, hooked to a 5 speed low hole manual trans, with a two speed rear end. The sound that engine made g splitting gears was amazing! I must clarify the information you’re given, there was absolutely no multi cylinder naturally aspirated Detroit Diesel engines! All were supercharged! While being a 2stroke there were no intake valves either, every valve, either 2 or 4 in the heads were only exhaust valves, as the intake is controlled by piston ports cut into the cylinders, hence the need for a supercharger to help in the scavenging that forces the intake in, then blow exhaust out for a brief moment before the piston closes the intake port, when the exhaust valves are closed for the creation of compression, with fuel injected at the precise moment for compression combustion! That’s why so much torque is created, there’s a power stroke on every revolution, instead of every other, like in a 4 stroke. Turbos are added to increase horsepower at higher rpm’s.
Many people considered them as naturally aspirated for the fact that they do require those blowers to run. They cannot naturally run without a blower, hence calling them naturally aspirated. And it makes full sense to me.
I had a Silver Eagle 40foot bus with a 6V92, that engine was amazing. It would always start, even in cold Iowa winters, on the hiway it would get 10 to 12 mpg, not bad for a 40 ft. 29,000 lbs. Bus.
I used to drive haul trucks (as in mining trucks, 80s Euclid R190s to be specific) with 16V149TIB engines (1800hp, a bit over 5000lb ft of tq) and they were so cool sounding. Other than say, a methanol powered drag car engine or a turbine powered aircraft, they are the single loudest engine I have ever heard. I've driven far larger and more powerful trucks since, but none had the personality of those enormous 2-strokes.
The first few videos I saw of yours I was kinda like yeah right. You either are the smartest gear head or you research the crap out of your videos. I love the diversity of the videos but still sticking to motors. Love your work sir and thank you for what you do
When I was a kid, the property next to ours was logged, and I spent quite a few days listening to those 4-53 powered skidders hauling logs up the hill.
I remember riding in railcars in Belgium which were powered with either one or two 6-71's or one 12V71, a lovely sound these things had. And standing at the trackside you could hear these approaching from 6 miles away.
My dad had 2 cab over trucks that pulled double trailers hauling hay from our farm. They both had Detroit 8V-92’s. They both had a supercharger and 2 big turbos. The tag on the motors were stamped 675 horsepower. They were monsters.
They have their very own grade of oil, API CF-2, the "2" at the end stands for 2 stroke. -2 oil is low sulfur to minimize coking, which is a problem for these engines. It also makes them best in marine applications, which never go down hill and the constant, steady loads experienced by boat engines reduces coking.
I work at a shop that started on Detroits, and actually still get some to rebuild from time to time. They still have a good amount of Detroit parts laying around.
Retired Farmer I can still hear a neighbor's farm hand working land in the early 1960's getting for spring seeding, he was likely 5 or 6 kms away. They were using an HD 5 Allis Chalmers with 2-71 like the one in your video. Like your GM videos. Thanks
Even though I'm an old subscriber this is the first time I've seen you, I had my doubts about you at first but as the videos you posted changed my way of thinking, I enjoy your way of displaying the various subjects. I won't drag this out so I'm just going to say thank you for posting this video for all of us to share, I really enjoyed it. Please continue with your content.
Thank you for showing them all running! You can't miss the sound of a screaming jimmy. Gm engines were used in boats, 2 running side by side could be configured to run in opposite directions. Ted from down under.
It sure was. In the old Crown school buses :) I rode to school in a few as a kid in 5th grade and as a high school student in the mid 80's. The high school had a bunch of tandem axle crown buses and some of them had 8V71's. I love the beautiful exhaust not of a Detroit two stroke :)
Detroit Two Stroke engines in any size have a distinctive sound . Even the little Singles you could pick it , once you know the Firing sound . All ridiculously LOUD and Brash and Grumpy when waking up . Outrageous Performance for their size as well . I love them .
I retired from doing service work at a KW/Ford dealer and working on Detroit Diesel engines was one of the jobs --tune up, overhaul and service/maintenance and even on 60 Series! the one thing most noticed was no matter how many cylinders, the 2 cycles all seemed to sound the same! there used to be a single cylinder unit at Interstate Diesel in Minneapolis, Mn - chrome plated!
I’ve been working heavy equipment for 45 years I thought it was a pretty good presentation I enjoyed it I was familiar with most of it but it was still a good thorough description something that more people need to do good job
The two stroke Detroit is arguably the most iconic engine that powered this nation, it's good to see examples running strong even today from so many year's ago.
I worked on just about all of these over my 42 year career at a Detroit Diesel Distributorship. I never saw the 12v53 and that 20-149. They are probably one of the reasons my ears are ringing right now.
Great video and thanks for sharing my video. The 2-71 I have featured in your video is a 2-71 Marine propulsion engine dated 1947. It was used in a logging tugboat. It is rated at 55hp
Not sure if you mentioned it but Detroit diesels are all 2 stroke, they use superchargers to force air into the engine via transfer ports on the cylinder sleeve. The supercharger is also used to force fresh air in to push the exhaust out through a exhaust valve.
Awesome vid man. I grew up around a lot of these engines as my family was in the logging field I remember the base camps in the middle of nowhere I'd spend hours crawling around heavy equipment and generally bugging the mechanics. Thank you
In the '70s I was privileged to work on 71 series in off road haul trucks at a salt mine in western Australia. To complete a "hot-set" on a 12V or 16V we had to do one bank, then warm the engine again to do the other bank.
As these become ever more rare I like and appreciate them more. They filled so many valuable niches but their time has passed (unless ways can be found to make them as clean and efficient as modern diesels, which may actually be possible if Achates Power is any indication). I also find myself in the very small minority of enthusiasts who prefers the sleeper approach (read silent but in this case with just enough of the characteristic sound so that those nearby will know).
my first truck driving job, back in 1992, I drove a 1975 GMC Brigadier that had a 6V-92. the fire truck around 6:40, the sound brought back memories... I could even smell it :)
Very nice compilation! I love seeing those used at tractor and truck pulls. I remember back in the 80s when O was growing up hearing fire trucks with these Detroit 2-strokes going past the house
Great to have the whole lot in one video along with specs. What a distinctive bark those motors have, I have driven a couple of things whith 6-71s in them. And as an extra note just think how many hot rods have had 6-71 and 8-71 derived superchargers on them.
Visio this is one of your best clips ever.! Thank you so much for the hard work in making it. I dont know where you would ever get any footage, but the 6-71 (and probably others) were produced as left hand rotation, and coupled with a standard right hand rotation 6-71 to drive a single shaft in landing craft, with two such units making a twin screw vessel
There was also a quad 6-71 unit with four 6-71s bolted to a common reduction gear driving a single propeller shaft. I was a Machinery Technician in the USCG and was stationed on a 95' patrol boat, powered by two 16V149TI main engines.
@@johnstuart3851 Ow wow! I would love to have heard your 149's running! And four 6-71 into the one shaft......this stuff is what made America great! I am a 66 year old Australian Diesel Fitter and Coach Captain. Bring back the old days!
I love how no matter how much exhaust is hooked up to a Detroit it will still be just as loud as a header dump
They're like a force of nature, it's so cool
The beast in the raw
The inlet made as much noise as the exhaust.
The DD is the most efficient way to turn fuel into noise... which in turn scares the load into moving!

The Euclid construction machinery powered by Detroit Diesels (both owned by GM at one time) were largely involved in the construction of the USA's Interstate Highway System beginning in the 1950s.
The loudest, most intimidating Detroit is a 6V53 on the stand with the intake silencer removed. A friend of mine invited me to a shop to see the governor being set by the head mechanic. That engine was absolutely screaming, and the volume? I felt it more than heard it.
I worked on 6V-53Ts for years in the marines. We set the red limiter at 3000, load tested they had to pull 2300ish on the stand.
Worked on most of these back in the 80'S 90'S and 2000'S. Nothing like them.
@@amsfarm1502 Great!
I drove a GMC truck with a "238" Detroit Diesel WE called it a "Screaming Jimmy" 10 speed Road Ranger, it was the fastest to get there empty , and by far the slowest to get there loaded... loved that Truck...empty you could shift gears as fast as your hand and arm could move...
The best sounding is still the 12V-71... the buzzin' dozen just sounds like everything right in the world!
All Detroit’s sound the best.
Detroit Diesel - One of the finest instruments ever created for converting diesel fuel into smoke and music.
2-Stroke DD...The most efficient way to convert diesel fuel to noise, without the side effect of torque...(They made great Horsepower, but pull them 500rpm below peak HP and they fall on their face.)

@@misters2837 Hahaha. You’re right about that. My uncle had a 238hp 6-71 backed by a 5 + 4. It would detect grades you couldn’t see with the naked eye 😂.
@@szymon6207 electric tach and mechanical engine incomplete swap..... but it screams its more gooder
@@dieseldemon8562 Its amazing, if you had the right Gear to keep it on the governor up the grade...you were fine...as soon as you got pulled off the governor, they would bog, and if your tried to lug it, as if it could be done, (especially a 92 series) you were rewarded with cracked liners...
People from the logging industry will likely remember the 353 the most as timberjack used them extensively in their smaller skidders from 60's onwards. So the story goes that in Canada up in the hills if you got lost while logging you could listen closely enough and hear a 353 no matter where you were and you followed the sound to safety. In Australia the little timberjacks are almost legend to the older cutters as screaming jimmies.
I run a old Clark Michigan rear steer loader with a 3-53 and you can definitely hear it for miles around.
@@dcrog69 A 4-53 High Speed engine can be heard in the next county. ;-) I live about 3 miles from a couple of pump stations that run N14 Cummins and Cat engines. As I worked at them, I can tell when they are running just by stepping out on the porch.
most people around here still use 353's, 453's and 653's in skidders and knucklebooms. No other engine can take the abuse of running wide open all day in cold temps
Awesome!
I have an international payloger with 353
I had a mate that drove an 8V92ta in a coach that did 100ks an hour up a mountain gradient an old lady on departure said to him she's never experienced anything like it. It was dry as a bone.
He also drove a White Road Commander 2 with same model engine hauling a quad float with dolly 220 000 lbs gross and left 2 444 Cummins powered trucks for dead on the highway and they were towing flatbeds nowhere near the weight of old mates truck. Cheers from Australia.
roar of long stroke engines is real music.the grunt of these old engines inspire to work hard.
The 6L-71 was used in almost every US made landing craft in WW2, it was extremely tough, extremely reliable (it had to be when used in a boat that came under a lot of gunfire), put out good horsepower and had great torque and had good fuel consumption (it could go a long ways on not that much fuel). It was also used in a lot of motor yachts and was turbo-charged to phenomenal outputs, almost 500 hp for the 6-71s, and would hold together. The V-16's were called "sweet 16's" for their output, reliability and smooth running. They also had a long production life which probably ended with environmental concerns, being 2-stroke they were a little difficult to make clean running, although they were economical and ran "lean".
Awesome engine series.
Even greta loves em
The company I work for still has a handful of trucks with 8v92Ts. Absolute monsters. We had one blow apart on the interstate, and was still able to pull the 40,000lbs of weight behind it for 150 miles with a hole in the side of it.
That's a Screamin' Jimmy for ya.
From my tech school days : the 53, 71, 92 etc refers to the cubic inches per cylinder.
"Most" but NOT all of the earlier Ingersoll-Rand drilling rigs I worked with were equipped with 12V71 Detroit Diesels. This video definitely brings back memories.
Detroit diesels are the most incredible diesel engines you'll ever see or hear, and are even better in real life. The amount of power they can make is truly INSANE
12V71 Twin turbo military engine could produce 600 HP. For 24 hours straight. Then it was overhaul time according to the military. A 12V71 NA engine could produce 340 HP for more that 14,000 hours without problems.
@@gravelydon7072 it worked too good so they had to fix it lol
Yes I worked on all kinds of them on the river boats including electromotive divisions EMD
Could always pick a Greyhound bus in Australia by the sound.
Greetings from Oz! Love your work! Back in the day, (30+ years ago) I spent a lot of time on 8V71's. When we were doing a governor set, one of us (2 man job) would have to sit on the blower housing to make adjustments. Sitting on an 8-71 blower with the motor running flat out without a muffler is an experience I'll never forget. I saw one run away once. The sound was amazing! They got it shut down before it blew up, fortunately. My other memory, not so good, was 2 full days of scraping off gaskets & washing parts prior to assembling the engine.
Where I used to work, we had a V16-71 that was used as an emergency generator. It roared. 😁
i love the sound of the 16v-71
We have a Cummins whose name I don't know for backup generators. It sounds okay and as a quad-turbo 50.3L V-16 it's awesome in its own right, but I really hope to see and hear a Detroit some time in my life
Detroits have been with me my whole life
.6-71 in marine diesel school. V-16-149TI
1KW gensets in fleet, then 3-53's in many skidders in the PNW, and 4-53's in excavators, Bobcats, and compactors in construction, to this day.
I work on these every day. Very happy to see a video on them that's correct. Good job on research.
When I was growing up and I helped my dad who was a mechanic on Detroit Diesels I fell in love with the sound of those engines! They were a masterpiece!
This is the most American thing in automotive industry I can imagine
Modular design that scales to a wide variety of potential needs thus becoming massively popular? Hey, I'll take it
These diesel engines are some of the finest ever built bar none.p
My personal favorite is the 6v53t. Just sounds amazing when you rev the shit out of it.
When I worked in the bush, before retiring, as a mechanic, working on the haul trucks and setting the racks on the 12/71’s got to be a noisy affair. Loved to hear them when running good.
the 12 and up cylinder counts sound so wierd and amazing at the same time. i love them. that v24 sounds like a runaway v12 or 8 yet that's just from the absurd number of cylinders
I worked on and with, a lot of Detroits over the years, mostly 71's, but a few 92's and 149's - mostly in marine applications - both generators and main propulsion,
I always respected them, they would tolerate a level of abuse that was difficult to comprehend... but I never loved them.
They were all loud and dirty engines, but definitely tough and reliable.
Hey, Strike Marine Salvage Sales! Thank you for using our video!! If you’d like to see more or talk about DD engines, let me know! Happy to help!
Are Detroit’s still being made or are they being kept alive.
@@brianfronius4166 yes and no. The 2 stroke Detroit’s have been out of production since the 90’s, most ended in 1995. The current engines are all evolutions of the 60 series 4 stroke DDEC computer controlled design that came out in 1987. Also GM sold Detroit diesel to Roger Penske who then sold it to Daimler AG so it’s not a GM division anymore.
@@J.R.in_WV , thanks my friend. The 2 strokes are a dream and marvel. I had a time with one in early and mid 80’s. Beyond sweet. Just don’t see or hear them anymore on road. It baffles me why they’re just not out there anymore. I appreciate you explaining it me. You strike me as a mechanic as well. If so, resurrect what you can and get ‘em back on the road again.
Hello again Visio! Over my 40+ years as a truck driver, I’ve driven my share of Two Stroke Detroit’s! T most recent was only about 10 years ago in an older GMC Car carrier. That was a 3/71, with a turbo, hooked to a 5 speed low hole manual trans, with a two speed rear end. The sound that engine made g splitting gears was amazing! I must clarify the information you’re given, there was absolutely no multi cylinder naturally aspirated Detroit Diesel engines! All were supercharged! While being a 2stroke there were no intake valves either, every valve, either 2 or 4 in the heads were only exhaust valves, as the intake is controlled by piston ports cut into the cylinders, hence the need for a supercharger to help in the scavenging that forces the intake in, then blow exhaust out for a brief moment before the piston closes the intake port, when the exhaust valves are closed for the creation of compression, with fuel injected at the precise moment for compression combustion! That’s why so much torque is created, there’s a power stroke on every revolution, instead of every other, like in a 4 stroke. Turbos are added to increase horsepower at higher rpm’s.
Many people considered them as naturally aspirated for the fact that they do require those blowers to run. They cannot naturally run without a blower, hence calling them naturally aspirated. And it makes full sense to me.
Torque? Now that's funny.
I had a Silver Eagle 40foot bus with a 6V92, that engine was amazing. It would always start, even in cold Iowa winters, on the hiway it would get 10 to 12 mpg, not bad for a 40 ft. 29,000 lbs. Bus.
I used to drive haul trucks (as in mining trucks, 80s Euclid R190s to be specific) with 16V149TIB engines (1800hp, a bit over 5000lb ft of tq) and they were so cool sounding. Other than say, a methanol powered drag car engine or a turbine powered aircraft, they are the single loudest engine I have ever heard. I've driven far larger and more powerful trucks since, but none had the personality of those enormous 2-strokes.
The first few videos I saw of yours I was kinda like yeah right. You either are the smartest gear head or you research the crap out of your videos. I love the diversity of the videos but still sticking to motors. Love your work sir and thank you for what you do
Thank you for the kind words!
When I was a kid, the property next to ours was logged, and I spent quite a few days listening to those 4-53 powered skidders hauling logs up the hill.
Who hasn't tried to imitate a Detroit Diesel engine when you were a kid playing with Hot Wheels or Matchbox trucks? because I was one of those.
all you have to do is go AAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHH
I always tried to imitate the sound of the green goblin truck in Maximum Overdrive which had a 8v92 in it :D
@@kenevans3659
I personally used the 6V71 for the smaller trucks and the lifted pickups and the 8V and 12V for the bigger stuff.
good times.
So true!!.. 🤣😅
I remember riding in railcars in Belgium which were powered with either one or two 6-71's or one 12V71, a lovely sound these things had.
And standing at the trackside you could hear these approaching from 6 miles away.
Detroit Diesel. The worlds most efficient engine at converting diesel fuel into noise!
And that's all they did/do..make fuckin noise
you spelt music wrong ;)
🤣🤣🤣
My dad had 2 cab over trucks that pulled double trailers hauling hay from our farm. They both had Detroit 8V-92’s. They both had a supercharger and 2 big turbos. The tag on the motors were stamped 675 horsepower. They were monsters.
Well put together film. Some research went into it and it shows
Tanks It was a exelent video, I was a tecnician from Detroit Diesel Allison engines dealer in México
6:52 it is INSANE how fast these diesels spool up.
With zero load against them. Any load and they're a dog. P.O.S.
It's no wonder with power on every down stroke.
I own a 42 ft boat with twinn 671N's 46 years old and still running strong !! Love them
I see the thumper--fully exposed to the outside elements--running water pumps out in the countryside. They're awesome little machines!
Thanks for the video.I worked on many DD's in the USCG.Like that sound.
They have their very own grade of oil, API CF-2, the "2" at the end stands for 2 stroke. -2 oil is low sulfur to minimize coking, which is a problem for these engines. It also makes them best in marine applications, which never go down hill and the constant, steady loads experienced by boat engines reduces coking.
Low ash is another term too. Always 40 grade.
Ikarus had a series with Detroit Diesels, those were extremly powerful.
What type of equipment and what model Detroit are you referring to. I'm interested to know cheers.
@@andrewking9761 Ikarus was a Hungarian bus manufacturer, the data is here busztipusok.hu/c56/c56-1.htm
It’s amazing how he finds the footage for each example. Very cool!
I work at a shop that started on Detroits, and actually still get some to rebuild from time to time. They still have a good amount of Detroit parts laying around.
Retired Farmer I can still hear a neighbor's farm hand working land in the early 1960's getting for spring seeding, he was likely 5 or 6 kms away. They were using an HD 5 Allis Chalmers with 2-71 like the one in your video. Like your GM videos. Thanks
In 1964 my Dad bought an Oliver 1950 tractor with the 4-71 engine. What a screamer, ear muffs mandatory.
Even though I'm an old subscriber this is the first time I've seen you, I had my doubts about you at first but as the videos you posted changed my way of thinking, I enjoy your way of displaying the various subjects. I won't drag this out so I'm just going to say thank you for posting this video for all of us to share, I really enjoyed it. Please continue with your content.
I love your dedication to the weird and often forgotten engines. Keep it up, man! I look forward to every upload.
Thank you for showing them all running! You can't miss the sound of a screaming jimmy. Gm engines were used in boats, 2 running side by side could be configured to run in opposite directions. Ted from down under.
The 2 stroke Detroit Diesel was a pretty common bus engine when I was a kid back in the 1970’s-‘80’s.
It sure was. In the old Crown school buses :) I rode to school in a few as a kid in 5th grade and as a high school student in the mid 80's. The high school had a bunch of tandem axle crown buses and some of them had 8V71's. I love the beautiful exhaust not of a Detroit two stroke :)
Detroit Two Stroke engines in any size have a distinctive sound . Even the little Singles you could pick it , once you know the Firing sound .
All ridiculously LOUD and Brash and Grumpy when waking up . Outrageous Performance for their size as well . I love them .
While i was watching this video my phone started leaking oil
I retired from doing service work at a KW/Ford dealer and working on Detroit Diesel engines was one of the jobs --tune up, overhaul and service/maintenance and even on 60 Series!
the one thing most noticed was no matter how many cylinders, the 2 cycles all seemed to sound the same!
there used to be a single cylinder unit at Interstate Diesel in Minneapolis, Mn - chrome plated!
I’ve been working heavy equipment for 45 years I thought it was a pretty good presentation I enjoyed it I was familiar with most of it but it was still a good thorough description something that more people need to do good job
The two stroke Detroit is arguably the most iconic engine that powered this nation, it's good to see examples running strong even today from so many year's ago.
6V53 was used extensively in armored personnel carriers like the M113 family.
M561 Gama-goat used a 3-53 (naturally aspirated).
The m109a6 paladin used the 8v71

Detroit Diesels, the best thing that ever happened... to Cummins.
Yes. Anybody with a brain, wouldn't of bought a 2nd unit.
I worked on just about all of these over my 42 year career at a Detroit Diesel Distributorship. I never saw the 12v53 and that 20-149. They are probably one of the reasons my ears are ringing right now.
Great video and thanks for sharing my video. The 2-71 I have featured in your video is a 2-71 Marine propulsion engine dated 1947. It was used in a logging tugboat. It is rated at 55hp
Thank you!
Nicely down!!!! great video! Long live the 2 Detroit!
Thank you, Daniel!
Man that v20 sounded amazing.
Not sure if you mentioned it but Detroit diesels are all 2 stroke, they use superchargers to force air into the engine via transfer ports on the cylinder sleeve. The supercharger is also used to force fresh air in to push the exhaust out through a exhaust valve.
The most efficient means of converting fuel to noise. Also the engine that won WWll because of the interchangeability of all the parts.
The 2 71 Detroit's were used in many HD5 Allis Chalmers dozers. You find a lot of them still running today. Older than I can guess.
Awesome vid man. I grew up around a lot of these engines as my family was in the logging field I remember the base camps in the middle of nowhere I'd spend hours crawling around heavy equipment and generally bugging the mechanics. Thank you
In the '70s I was privileged to work on 71 series in off road haul trucks at a salt mine in western Australia. To complete a "hot-set" on a 12V or 16V we had to do one bank, then warm the engine again to do the other bank.
As these become ever more rare I like and appreciate them more. They filled so many valuable niches but their time has passed (unless ways can be found to make them as clean and efficient as modern diesels, which may actually be possible if Achates Power is any indication). I also find myself in the very small minority of enthusiasts who prefers the sleeper approach (read silent but in this case with just enough of the characteristic sound so that those nearby will know).
my first truck driving job, back in 1992, I drove a 1975 GMC Brigadier that had a 6V-92. the fire truck around 6:40, the sound brought back memories... I could even smell it :)
Super ze niekto z mojho okolia ma tolko sledovatelov,paradne a naucne videa.Palec hore ;-)
Ďakujem, vážim si to veľmi!
4-53 is actually my favourite detroit diesel engine because of it's sound at higher revs per minute
Very nice compilation! I love seeing those used at tractor and truck pulls. I remember back in the 80s when O was growing up hearing fire trucks with these Detroit 2-strokes going past the house
I've always loved that 20v-149 clip because it starts with the big dude apparently shaking off a heart attack that's making his left arm sore.
I admire your progress, man! Improved English and a lot of subscribers! Your efforts and knowledge are appreciated!
Detroit Diesel, turning fuel into noise since 1938.
Damn good engines
Great to have the whole lot in one video along with specs. What a distinctive bark those motors have, I have driven a couple of things whith 6-71s in them. And as an extra note just think how many hot rods have had 6-71 and 8-71 derived superchargers on them.
Detroit's are my favorite engine in diesels! Great power and nothing beats the sound of those reved up 2 strokes!
Visio this is one of your best clips ever.!
Thank you so much for the hard work in making it.
I dont know where you would ever get any footage, but the 6-71 (and probably others) were produced as left hand rotation, and coupled with a standard right hand rotation 6-71 to drive a single shaft in landing craft, with two such units making a twin screw vessel
There was also a quad 6-71 unit with four 6-71s bolted to a common reduction gear driving a single propeller shaft.
I was a Machinery Technician in the USCG and was stationed on a 95' patrol boat, powered by two 16V149TI main engines.
@@johnstuart3851 Ow wow!
I would love to have heard your 149's running!
