At 18.6 liters, this engine is anemic compared to smaller displacement Cats, Detroit and Cummins. 760hp/2200tq sounds impressive on paper but little 12. 7 Detroits are capable with an ECM tune, of 625hp/2150tq. 6nz Cats with a good ECM tune will outperform this engine, and do it with almost 2.5 liters less displacement.
@@TheRoadhammer379 Yes with today's common rail diesels it is easy to make big power. But it is also easy to crank this thing up with bigger injectors and turbos. The Detroit is still a mainstay in tractor pulling because the engine is so robust. Also keep in mind Detroit's were all made for continuous full power output so they could be used as generator stations, water pumps or marine engines. So the output may look low by today's standards but they are incredibly durable even today and they were plenty powerful back in their day.
That truck is a classic design of the 60's and 70's seen in logging trucks. I worked as a diesel mechanic for an excavation company in the 70's and most of the fleet were cabover Kenworth 12 wheeler dump trucks and everyone was powered by 6-71 inline 6 Detroit Diesel. They were loud and oily, when it was not the motor leaking, it was the hydraulic system. I've seen runaway DD engines, it takes guts to slip under the cab to close the air intake trap. They were prone to running backward also when the stop the engine did not work and we had to stall the motor with the clutch. They were equipped with air starters, very loud and not reliable in winter. We also had a dozen of Mack B-81, B-61 and a towing based on a Mack DMM800 6X6 that I was operator of for 2 years, best time ever covering the fleet for breakdown. I have been retired for a while now and I still have that diesel smell tingling my nostrils, will it ever go away.
You know ,,,those Detroit's run backwards you had 13 reverse gears and one forward ,,,lol they would intake through the exhaust and stink coming out through the old oil breathers ,,,,that's why they used the old Detroit's in boats because one engine turned to the right and one turned to the left,,,coast guard boats used them for years
@@briananderson3801 That was to eliminate the expense of a reversing gear assembly on one prop shaft. If you have both props spinning the same direction, the boat won't sit level in the water when under power.
My son got my 12 valve cummins running backwards on the boat launch once. I didnt think it was possible with a 4 stroke. He got out and refused to ever drive it again.....hahaha

My dad took me everywhere u could drive to in the u.s. in the cab of a old peterbilt with a Detroit in it. I have flashbacks to this day when I hear on. Just friggin awesome
I drove a 16v71 in a r50 Euclid . That engine would turn 3500 rpms and when you got out at the end of the day it felt like the sound went right through you . To this day I believe that sound effected your central nervous system as the exhaust just came right out of the hood . The better ones would divert the exhaust through the dump body but not mine .
Heh heh, the 16V71's were governed at 2100 actually (might have *sounded* like 3500, since they're 2 stroke), but they really didn't turn very fast to produce between 630 and 760 hp.😉
I used to run 16V's and 12V' in Logging yarders up to 120' Towers and I agree the sound and vibration would go right through you. Had to wear earplugs under earmuffs but man when you lit into a big heavy drag coming up a mountain from 2000' feet below and 100,000 lb line pull it was some awesome feeling. Dangerous as hell if something broke though which it often did.
@@danw1955 LOL !!! I sat on a milk crate for a seat . The exhaust came right out of the hood no muffler . And because I was a young know it all I never wore ear protection and that's why to this day as I am writing this and I am 66 years old my ears still ring , SIGH
My father drove for about sixty years. He drove a 75w900 for about a decade. It had a 445 Detroit,15 speed with 4:11rears. He put almost a million miles on that truck. Five years were spent hauling steel for a company called George Transfer and Rigging. The feds put them out of business. Those were the outlaw days! My dad would constantly load the wagon full! RIP "Hotshot"!
last time i saw one of these, the smoke escaped and it got a brand new inspection hole in one of the blocks. nice to see one that works properly! :) love the sound! my neighbours would also love it!
Hayes, an unreal tough truck brand. Then top if off with 18 liters of JADE GRENADE... Superb capture, I thought i recognize that truck from Saskatchewan.
This HD model was apparently custom built in someone's shop, as the 16V-71 Detroit Diesel was available on the WHDX(wide) model w/ offset cab. The 16V was big power back then w/ 636 h.p. This truck has no hood sides to accomodate the 2 turbos and exhaust stacks out the back of the cab. On the offset cab models the dual exhaust w/ be on the passenger side back of cab.
Gotta love the old 2 stroke Detroit's this bad ass truck got to v8 Detroit's bolted together worked on alot of these the navy uses them to run generators on the ships i bet that bad boy pulls like a freight train got a old Peterbilt that was my dads truck has the 8v71T in it and now im in the process of restoring it and keeping it as a family heirloom my dad love this truck more than my mom i think lol
I met him at talked to the old guy that built it and is seen driving in the video, I saw the truck too, it’s huge. He said the front half is a Hayes, the engine is from a generator, the back half is the back half of a kenworth (including the rear ends). The engine compartment had to be stretched 2 full feet to fit that Detroit. He did everything himself including welding the two trucks together. He drove rigs for 58 years I think he said, just recently retired, and still drives em for fun. He trailers it around all of North America for shows. I saw it in Canada
DailyDieselDose I remember, that book was huge! I wish I had the time to sit down and look through it cover to cover. I strive to become like the old gentlemen who owns the truck, really cool guy
What a beast! What’s crazy is that you can get the same performance out of a tuned X-15 Cummins or a modern Detroit DD-16, both inline 6-cylinders, as you could a V-16 Detroit. One things for sure though, no modern motor comes anywhere close to as awesome sounding as these old two-stroke Detroit’s.
True but, an ISX or DD16 turnt that tight won't be around 50 years later like this. Also, you could do an in frame on one of these with a tool box that could be carried by one man. That's why an ISB in a Ram 3500 is almost 400 HP and 1000ft lbs. In a class six truck, they're 300/750. However, their B90 is 1M miles. The million mile 5.9/6.7 in a 3/4-1 ton aren't running 90 PSI boost.
no you can't lol, its impossible. Every cylinder fires per rotation of the crank, 4 strokes suck at making power. A 14L 12v71 stock makes 425hp yet a 14L Big Cam cummins makes 350hp with a turbo lol and is actually a slightly bigger engine!
You're actually quite wrong. There was the N(natural aspiration), T for turbo, TA was turbo aftercooled. There was a TTA designation but it was not meant as twin turbo, it denoted Tailored Torque Aftercooled aka Fuel Squeezer.
This Looks like a 16V71T that could have a horse power rating of 700 hp and more torque than the 16V71. The 16V71 could have a rating of 636 horsepower. Great video!
Beautiful tractor. What gearbox is behind that massive engine & how many horsepower does it develope?

A lot of folks don't realize that some of the most heavy duty truck chassis came out of British Columbia Canada, Hayes, Pacific, Western Star (original plant was Kelowna BC ,Freighliner Canada, Canadian Kenworth........all of them NAFTA'd out of existence
2 stroke life: they slobber and mark their territory, have two throttle positions where they’re happy and convert fuel to noise very well. Miss them. I only see 15-20 a year these days.
Would have loved to see more in detail on that same truck. Inside the cab under the hood under cab long bed frame rails. It would have been nice Food For Thought next time.
@@stevegould1730 N is naturally aspirated. But still relied on the blower for scavaging. T had a turbo (still fed into the blower inlet) that would actually create some boost and increase output. TA was turbo with after cooling to decrease charge air temperature.
@@bills6093 That looks like an indusrial version 4,800# rather heavy then again my Murphy Diesles are 1,103 Cubic Inches 110 HP wide open 1200 RPM 5,500# I weighed one once that I bought at the scrap yard for spare parts I have one with 30,000 hours on it ..
@@mikeskidmore6754 No, it's a vehicle engine. Detroit 71 series is uniflow, so it has to have a blower for intake air. Won't run at all without a blower. So to get any boost, you have to use turbos. It's two 8 cylinder blocks masted together.
@@bills6093 the 6-71 rund the Blower at 2.05% of engine speed many DD engines have a Blower only no turbors .. Ironically they call a 6-72 with no Turbos a 6-71-N for Naturall aspirated..
Practical? 😂 Nowadays, you can get more horsepower out of a motor half the size and weight. Unfortunately the days of these motors ruling the roost are gone.
@@klub5158 Absolutely correct. The little 12.7 Detroit can easily be tuned for 625hp and 2150tq, no engine mods, just a good ECM tune. So besides cool factor, these 2 strokes are obsolete.
Good for you Rosemarie! Every time I mention "prime mover"; people look at me funny! That's exactly what it is! Like when I use the term "traction plant", that's a tractor! 😅
kmcwhq it’s a TH-cam video with no narration. The truck could have shut off 2 minutes before he started it, though the the blue smoke from a DD 2 stroke suggests it hadn’t been run up enough to clear it.
@@funone8716 ehh it's effy we had a pump as soon as it read oil pressure we push ours to 2,250rpm cold or hot you'd think it will damage it but running 10hrs a day everyday for years and years it starts like new runs like new they like abuse unlike other diesels
@Keaton Chatenay The organizations doing that can also afford to replace one when it pops from abuse. They can take it, but for how long. They used to do that with Fire trucks as well.
8V and 12V sound fantastic then you step up to the 16V totally different. Idk if it's true never looked it up it someone once told me there was a 24V also. I got no idea don't see and clips of a 24V Detroit

no you can't lol, its impossible. Every cylinder fires per rotation of the crank, 4 strokes suck at making power. A 14L 12v71 stock makes 425hp yet a 14L Big Cam cummins makes 350hp with a turbo lol and is actually a slightly bigger engine!
CRQ5508. The DD series of engines are not actually Detroit's, But are really Mercedes engines! 😕
Awesome piece of history 16v71tt, tt denotes twin turbo I believe. Beautiful truck!
You're actually quite wrong. There was the N(natural aspiration), T for turbo, TA was turbo aftercooled. There was a TTA designation but it was not meant as twin turbo, it denoted Tailored Torque Aftercooled aka Fuel Squeezer.
Sorry but TT on a Detroit diesel stands for ''Tailored torque'' TA turbo aftercooled.
This Looks like a 16V71T that could have a horse power rating of 700 hp and more torque than the 16V71. The 16V71 could have a rating of 636 horsepower. Great video!
Now that my friend is a man's trucks
Stack er' high an' let er' fly!!!!
I just found my new Grocery Getter.
Used to maintain those engines in the 85ton terex dumpers. Music to your ears!
This is what you should have to drive in trucking school.
Man this thing is gorgeous
You can almost feel the ground shake!!
Looks like a truck for rig moves. A spin in this would be fun.
I miss going to those truck shows
Beautiful tractor. What gearbox is behind that massive engine & how many horsepower does it develope?
A lot of folks don't realize that some of the most heavy duty truck chassis came out of British Columbia Canada, Hayes, Pacific, Western Star (original plant was Kelowna BC ,Freighliner Canada, Canadian Kenworth........all of them NAFTA'd out of existence
Now that's what you call a heavy duty front axle
That’s power it can idle up that ramp!!
Cool as hell. It's still an old 2 stroker. Big paperweight. Flatland, feather hauler.
You can still hear Detroit Diesel engines at night in NYC. Either generators or older municipal vehicles.
16v71 = 635HP of pure noise
2 stroke life: they slobber and mark their territory, have two throttle positions where they’re happy and convert fuel to noise very well.
Miss them. I only see 15-20 a year these days.
I painted them in seattle, alpine green
Looks like the logging trucks of my youth on Vancouver Island pulling 250,000 lb loads
Would have loved to see more in detail on that same truck. Inside the cab under the hood under cab long bed frame rails. It would have been nice Food For Thought next time.
Thank you. I did a walk through of the show field where I spend a few more moments on this truck.
Nothing like the sound of a Detroit ! Now that’s a work truck!
YUP YOU WORK ALL DAY TO GET ANYWHERE
Trucks back then were made to last a long life
That's an awesome rig.
Sweet! Love the twin turbos
Such a beautiful truck !!
Your channel is the best. My favourite You Tube channel ever.
Thank you! I love those old trucks.
DailyDieselDose I know. I hate the new trucks, but the ones from the 70s are my life.
sounds like its going to take off!! awesome
I love big rigs and I especially love one with my last name on the front of it lol
What a FRIGGIN BEAST.😲👍🏻👌🏻🔥
The old1970's expression, that thing is "BOSS" as hell!
Damn she sounds good sounds like a lot of power
Nothing like revving the piss out of a cold motor...
I wonder how many gallons to the mile it gets?
18 liters of vintage 2 stroke diesels! My g fuel economy estimate is 3 mpg if diesel fuel! Towing capacity is 150,000!
Jakes would sound amazing on that thing.
What did you say I can't hear you
I drive Detroit powered trucks at the airport I work at this dam thing is as bad ass as it can possibly get
And to think...there are those who say cows are letting out too many emissions....long live the Detroit’s!
Where these trucks originally built with DD?
What's the HP & Torque of 16 v71?
I know I'm splitting hairs, but wouldn't this particular Detroit Diesel engine be classified as a 16V71T?Great channel. Thank you.
M Jones turbo. So yes.
Maybe even 16v71 TA. There were N, T and TA versions.
TheRoadhammer379 What does the N and TA stand for?
@@stevegould1730 N is naturally aspirated. But still relied on the blower for scavaging.
T had a turbo (still fed into the blower inlet) that would actually create some boost and increase output.
TA was turbo with after cooling to decrease charge air temperature.
That's beautiful ❤️
Love it!
I am guessing it did not come with those Turbos ? Hook it to a pulling sled or a Log Trailer .. I would like to see it under a Heavy load..
@@bills6093 That looks like an indusrial version 4,800# rather heavy then again my Murphy Diesles are 1,103 Cubic Inches 110 HP wide open 1200 RPM 5,500# I weighed one once that I bought at the scrap yard for spare parts I have one with 30,000 hours on it ..
@@bills6093 I am gonna say the Turbos on that truck were added on later.. Surprisingly the Turbos on that Industrial motor were intercooled ..
@@mikeskidmore6754 No, it's a vehicle engine. Detroit 71 series is uniflow, so it has to have a blower for intake air. Won't run at all without a blower. So to get any boost, you have to use turbos. It's two 8 cylinder blocks masted together.
@@bills6093 the 6-71 rund the Blower at 2.05% of engine speed many DD engines have a Blower only no turbors .. Ironically they call a 6-72 with no Turbos a 6-71-N for Naturall aspirated..

Man listen'n to her rev up made me wanna do my best Jim Carry hip dance move!
Does anyone if these old mammoth 2 stroke motors could fit into a modern truck and be practical?
Fit yes. Practical...probably not. Would be cool though!
Fit in the hed maybe. It's pretty heavy and long.
Practical? 😂 Nowadays, you can get more horsepower out of a motor half the size and weight. Unfortunately the days of these motors ruling the roost are gone.
@@klub5158 Absolutely correct. The little 12.7 Detroit can easily be tuned for 625hp and 2150tq, no engine mods, just a good ECM tune. So besides cool factor, these 2 strokes are obsolete.
What a beautiful Machine"With Heavy Duty Leafspring!!Suspension!
that is soo awesome !
You should be able to find one these in your part of the world!
they are out there just a little out of my price range. An acquaintance of mine is restoring one in Alaska.
Sure'd like a loaded pulling video of it.
What is name truck?
OMG!: Gorgeous symphony!!.. 😍
I'm curious, did the 16v71 come with turbos in 1966?
Howard Bardsley yes
what is the Cylinder bank angle on this engine?
60°
i bet in low low range this thing probally does 3mph at redline and will pull anything and everything. would love to see it at a tractor pull.
Excellent.
Is it original with the v16
NOW THATS ONE BAD ASS PRIME MOVER
Good for you Rosemarie! Every time I mention "prime mover"; people look at me funny!
That's exactly what it is!
Like when I use the term "traction plant", that's a tractor! 😅
30 feet to the gallon?
For a second I thought the golf cart was hooked up to that flatbed trailer 😂
Now dats a truck.. Old Hayes I love those trucks... 16v71 Detroit wow.... Whats the hp 550-600 easily.... dream man
Nice truck. Dude's not showing it any mercy on startup, that's for sure.
kmcwhq it’s a TH-cam video with no narration. The truck could have shut off 2 minutes before he started it, though the the blue smoke from a DD 2 stroke suggests it hadn’t been run up enough to clear it.
@@jimmyaber5920 The blue smoke suggests its cold and he should keep his foot out of it
@@funone8716 ehh it's effy we had a pump as soon as it read oil pressure we push ours to 2,250rpm cold or hot you'd think it will damage it but running 10hrs a day everyday for years and years it starts like new runs like new they like abuse unlike other diesels
detroits stop working if you show em any mercy!
@Keaton Chatenay The organizations doing that can also afford to replace one when it pops from abuse. They can take it, but for how long. They used to do that with Fire trucks as well.
Awesome truck
Looks like Hayes began with an engine and built the truck around it.
8V and 12V sound fantastic then you step up to the 16V totally different. Idk if it's true never looked it up it someone once told me there was a 24V also. I got no idea don't see and clips of a 24V Detroit
