V12 Detriot Diesel 525HP

Setting the engine up and breaking it in.Remember this engine is just being started after a rebuild so that's why it's smoking from the assembly lube and the rack will be set-up to stop the hunting etc etc. Then the oil is changed and the engine painted. These engine's go into Euclid mining rock trucks,and they were in many other equipment/vehicles.The engine has rebuild heads,turbo's, blower, water pump,all internal parts and the air compressor All done in the great north of Canada

[@joeymdorsey52185]

GM diesels are some of the most reliable engines ever made... I've worked in the marine industry since high school,and in my experience marine applications are the ultimate stress test. We had a 71 series V16 that had a broken crank but did'nt shear completely,and that engine ran for 6 hours at 800 rpm to get us back to port.

[@0riginalxx0utlaw]

in my diesel tech class my instructor was able to find an 8v71 DD in an old totaled semi, we just got done rebuilding it and will fire it up on Monday! =D

[@808TheDuck]

Post a video!

[@opieknievel]

I don't know how many times I've watched this video. I LOVE the sound of this Detroit. One of the best sounding V12 Detroits on youtube, in my opinion.

[@researcher4good]

To those who think it's a v6, no it really is a v12. 12V71T to be specific. To those who think it's being revved too high, no. It's a 2 stroke with 12 cylinders. These redline at 2100 rpm. At that speed, a cylinder fires 420 times per second which makes it sound like a V8 four stroke revving at 6300 rpms. 50% more cylinders, firing twice as often.

[@mikenkfalls]

These engines red line at 2500 at load and 2750 without a load. I have had many of the older 8v71's at 2500 with a load. These are not engines that you can lug. They have to be ran hard at high rpm. If you lug these engines they will blow.

[@LizardKing0851]

I drove a lot of 2 cycle Detroits but never a V12. We drove the 318s from 1900 to 2350. I'd kill to stuff a V12 in my 379 Pete.

Do these diesel engines have valves??

[@matthewbeasley7765]

These Detroit V-12 turbo diesels were used as a STARTER MOTOR on a General Electric Frame 5 gas turbine generator. They turned a torque converter and a jaw clutch to spin the turbine up to firing speed. For 3 minutes they screamed at wide open throttle, then went to idle cool down. The turbine put out something like 30,000 horsepower. I love that Detroit sound....

[@patrickwarby1140]

Absolutely class sound. Pure power.

[@lukemoore6420]

i ran a couple of these on the dyno back in the day, the sweetest sounding engine i ever heard, if the rack was run right

[@TSorovanMHael]

I love how those 2-stroke D.D.'s sound like they're really screaming the RPM's

[@fudgepanda1]

Back in the late '70s/early '80s I used to drive a Bedford TM running at 32 tons fully loaded. That truck took a fair time to become popular because it had a DD 6V-92. Very few companies wanted one as they were really committed to Cummins and Gardner diesels. Drivers didn't want it either because in our firm, they were all older than me and brought up on big, slow running motors, but I loved that wagon. It had been a demonstrator for a dealer so it had a nice paint scheme and twin vertical stacks, and it sounded awesome, especially going uphill, although it also looked like an air pollution monster as you were really aware of the exhaust smoke because of the stacks. The TM became more popular when it got the Cummins N14 and L10. They were cleaner and more economical but they never attracted the attention (good or bad) that my Detroit did.

[@rolomaticz5009]

Yes, that Detroit sounds just like a V12 Deutz. Two of those on the planetary reduction gears powering the props would be awesome. They make great off shore fishing troller power plants! Two of these engines could power a 150-200 foot yacht or fishing vessel up to 35 knots. Sweet music from the exhaust pipes!

[@hectorestrada7239]

I agree 😊

[@whorayful]

BTW the engine shown is a 12V71 T. A second world war designed General Motors engine that just didn't die. It's little brother the 6-71 was used a lot by the Navy during WW2 in landing craft, PPBs, and just about anything that needed moving. Before they went out of production in the early nineties GM made a 24V71, two of the 12's bolted together end to end, that my friend was a sight. "General Motors 2 stroke diesels, the most efficient engines ever built for turning fuel into noise" love 'em.

I pump barges for a living and I just love those old Detroit 12V71s. But EPA is cracking down so we are using more of the 8.3 cummins and 6081 John Deeres. Those old Detroits sound like they are running 9000rpms and only turning 1800. Good video.

[@robertreznik9330]

I farm on the Texas Great Plains. Water well drillers often use the 8 72 and 12 71 Detroit to drill and bail 100,000 of wells is this area. There is nothing like a 12 71 on a cable tool pulling out the 14" diameter bailer from a 800 ft well in a minute or so round trip. This action is to clean out the drilling mud and set the gravel between the sand formation and casing.`

[@epistte]

+Robert Reznik Who still uses a cable tool drill rig in 2015? Those things were antiques even 30 years ago.

[@robertreznik9330]

+epistte I said they use these 2 cycle engines on a Bailer. Which is a cable tool rig that cleans out the well after the casing and gravel pack is in place. Some drillers use a 2 cycle on the turn table and mud pump. Because they like the simple dependable 2 cycle had about 30 hp / cylinder. If the power stops then expensive drill stem is stuck in the hole. The driller I used on my last 6 well was Hydroresources they use Cats the one before was W.D. Jones Drilling they use Detroit..

[@RMTTR640]

It's an 8v 92...there is series 53,50,60,71,92, and 149...do a little homework so you know what your talking about

[@ThePaulv12]

About these parts I have seen on a drill rig (from a distance being driven in traffic) either a 12V92 or a 16V71 (poss even a 16V92). I can never get close enough to tell but I can see 2x cylinder heads on one bank and a turbo on one side sitting like this in the vid but on top of an inverted 'Y' so it can't be a 12V71. It may even be a 149 Series I just can't tell as it's always moving. It's on an old twin steer bogie drive rigid and has the derrick?? laying across the length of the truck and over the top of the cab and the detroit. I wonder what powers the truck?

[@jeremiahsimpkins5943]

u never know until u try

[@emilpoulsen]

why slow?

[@Steelgiraffe666]

emil poulsen depends on how big your Honda is

[@vtr0104]

It would go slow because, in spite of what it sounds like here, it's only turning a little over 2000 RPM. It has torque, for sure, but your problem would be the weight of the engine itself. Detroits were never light engines, mainly because they were fitted to trucks and buses that had huge frames to support them. Considering the Honda joke usually refers to a Civic hatchback, which is a uni-body construction, this engine would literally drop through its floor if you tried to install it. And yes, I said floor, because you'd not be able to fit it in the engine bay... And given the size of the transmission and rear-end needed to run this thing, you're better off trying to swap it into a Ram or a Silverado , and even there you'd need to modify it heavily. But hey, at least those were made to tow things, which is what this engine was built to do :)

[@KeithRa68]

I think gm under estimated hp on Detroit engine. I remember my dads 8v71n it had 333hp rating with a Allison dr750 automatic transmission in a dump truck. I had the throttle set up only to open up 1/4 of full throttle. I done that to keep him from breaking drive shafts. I'm thinking that 12v more like 750 or more HP.

@kamphwagon1 I agree...buffer screw needs a little tweaking. Rolls a little at an idle too. This is what most veteran truckers would consider "ear candy", a very bad disease indeed. But you have to die of something, so it might as well be from overexposure to loud diesel engine noise and excessive exhaust fumes to end your life in the right way.

Nice answer. Does VolksWagen/Audi know it?

[@goober239]

+Joe Krushelnicki Actually they are starting to come back. Look up the Ecomotors company. NOx emissions are greatly reduced

[@nojoek152]

I am aware they have started making a comeback, I understand a drawback is a relatively narrow powerband.

[@slimchancetoo]

+Cem Sezer I 'drove' 8-71 T and 8-92 TA engines on the highway for 30 years pulling one or two trailers loaded with cubic freight but quite often heavy freight. The Detroit 2 stroke was a great sounding engine and when geared up properly and with the right diff ratios a great drive. Only problem was they did not have much torque and hated heavy loads in hilly country. I would 'round up all the Cats and Cummins guys on the flat ----- and give them a wave as they passed me on the next hill. They were an engine that had to be driven as if you wanted to blow it to pieces - and quite a few guys did just that..

Brandon Taylor its called a blower and it doesn't make any boost

[@MidniteLiquid]

Mason h Agreed! It is a blower. I was using the term Blower and Supercharger interchangeably and rather incorrectly, since a two stroke diesel cannot naturally aspirate itself, so it would be more correct to call it just a plain "charger", or more commonly, a blower .... :) I made a quick comment without thinking of the technical accuracy, and most often Blower=Supercharger on an engine.

The last two numbers denote the fuel delivery. 90 is 90 ml of fuel per 1000 strokes at full fuel rack position. 05 is 105 ml, 15 is 115 ml of fuel and 25 is 125 ml of fuel.
