- 12V71 Detroit pulling Satus Pass in Washington, 3107 FT. 1973 Kenworth W-923. Good sound. The first few minutes not much pulling, then we get into the hills. Light load going up and down hills with Jake. The left window is down about two inches, I lowered the right door window about two inches after cresting the hill.
Detroit for sure real deal love the sound for real
Drove a many a mile listening to that sound. That was back in the day when there were REAL trucks and truckers!
they still are real trucks and drivers. real trucker doesnt talk trash about younger drivers.
Me too! That's why my hearing is not so much. The price of cool ain't cheap
I know this is an old video, but what's the latest with this truck? Love me some Jimmy's. I grew up in Eastern WA.
I had a GMC cabover with a 318, my foot hardly ever left the floor, it sounded like it was going a hundred but was on the struggle bus at 70 loaded with 45000 sometimes with fire coming out of the stacks due to the N70 injectors out of a 12V71 Quarry pit truck, it was cheap, dependable, indestructible, easy to work on, a little under powered but made money.
@Derrick Woods depends what my boss has. Why to always shit on youngers necks? Is it that you didnt even have proper sound insulation on things and now you all think your cool n shit when you dont hear stuff?
The driver shifts like a boss!
It's like music 🎶 to my ears. I will never get tired of that sound. Some people like white noise machines, I love this sound. Thanks 👍 for posting.
The radio was obviously invented by someone who had never heard this sweet music....
Good driver, keeps the revs up. That baby is happy at 2100 rpm. Really happy. God I miss that sound. When I was a kid, every truck sounded like that.. damn near.
The sound of these Detroits winding out just gives me chills, good ones. I grew up on old Hwy 77, like everybody says, went to sleep listening to their song.
I wish this was on a 12hr loop so I could listen to it all night while I’m sleeping like “white noise” for adults (ive never even drove a truck bigger than my pick up)
I believe there are white noise vids on TH-cam of diesel engines running. You'd have to search if there is one for a 2 stroke
Awesome sound. I don't know a thing about trucks. We used these 12-71 Twin Turbo Detroits as STARTING MOTORS for General Electric MS5001 powered heavy duty gas turbine generator sets. They were rated 600HP, ran about 10 minutes total in a start cycle.
The Detroit fired up when the operator selected Start from the control cab. It would idle for 10-15 seconds then run to wide open governor. There was a straight pipe up out of the accessory cab and it was LOUD. There was a Twin Disc torque converter on the Detroit that drove a jaw clutch which engaged the turbine compressor end and ran it to 1000 rpm. The 10 turbine combustion chambers would ignite, warm up for a bit, then the Detroit would help it accelerate until the turbine would begin to run on its own, build speed and disengage the jaw clutch.
The turbine would accelerate to 5100 rpm governor speed and the 12-71 would idle for a few minutes to cool down, then shut off. GE chose Detroits because they were able to ''black start'' a generator package where no outside power was available. Within 10 minutes or so the packaged generator set could be putting out 24 Megawatts into the power grid. That's 32,000 horsepower.
I worked on a pair of these units in Venezuela. I blacked out an entire region on the East side of Lake Maracaibo all day because I poked a screwdriver in the wrong place behind the control panel. Woops. I always loved that 12-71 scream and wanted to build some kind of hot rod with one. Then somebody built Pissed Off Pete....
Yup! Mene Grande, Venezuela. The people at the Rosati Hotel weren't all that amused. They all knew that the big dumb GreenGo living in the Bridal Suite was supposed to keep the power on! $16 a night for the room as I recall. Gas was 11 cents a gallon equivalent in US Dollars.
great story
8/8 gr8 m8 would reccomend
kimmer6 ran a 40mw Westinghouse gas turbine fast start with V12 cat or Cummins with air start..... cold standstill to 40 MW in under 7 minutes
the amount of diesel that thing burned was ungodly
How many teachers were wrong. See, you can make money staring out the window! Very nice video, thank you for sharing.
I could sleep to these make me remember riding with my dad when I was a kid.
Nothing like the sound of a DETROIT dam I miss hearing that I went on the fire Dept in 1969 we got the first Diesel eng was a 671 5 Speed we ran the hell out of it it leaked a lot but never ever failed us..
I never ran a 12-V in a truck but did in pans and haul trucks and this is what they were made for. Up this hill and down, up this hill again. It's a mighty mighty long road, One ain't got no end!!
A real driver in a real man’s truck. One hell of an engine v12 Detroit 👌
Thanks for the wonderful memories & ride in that beautiful truck. Wish the roads were full of those professional drivers like this now days. What a great job of keeping that V 12 singing.
Yep I'm hooked on the sound of this big jimmy.
Music to my ears. The sound of American ingenuity and industry. WINNING
Happy 4th of July folks. Yours in Detroit heaven. Cheers from Australia.
This is like watching a conductor leading the orchestra....Just Incredible and BEAUTIFUL...Thank You
"Joe Hickey".... would have been even More "Incredible and BEAUTIFUL"..... if Mike had "sticks" in his KW and his 12 opened up to 2,850 rpms, like mine were.
You've never heard "music" ... until you've heard a 12V71TTi start reaching 2,400 r's and up... under load with twin turbos, 100mm injectors, 2 degrees advanced timing and Spicer Dbl Over 6X4's behind it..... THAT - WILL give you "goose bumps" and make "the hair stand up on the back of your neck" !! THAT... is BRUTE Power !!.... and the kind of power that I built (the engines), owned (had 1 Pete and 2 KW's [like Mikes, here in the video] that were 12V powered), drove and enjoyed for nearly 24 yrs (and 3.7 million miles) of my 47 yrs of trucking as an owner operator.... and have been kicking myself for years, now... for selling them. Sure miss them.... and the days when trucking (and this country) was something to be proud to be a part of... and was a Respected profession, by Everyone... including the police, the general public and even the "early" DOT people after the ICC was dis-banded.
Take Care.
HI 2Stroke DP. I was just wondering if you could fill me in on the possible mods for the 12v71. I'm thinking about buying a core engine first and then doing the mods and finding a truck afterwards. I would probably choose an early 80s kenny similar to this one, or a Peterbuilt 359. I will definitely be putting on Twin turbos, definitely hi-flowed and probably get the top manifold from a 92 or 149 engine, even if I have to cut it down. I was thinking about doing away with the supercharger (do you need them to run?) and fitting an intercooler instead, otherwise maybe having the supercharger fitted with Nylon vanes for more efficiency. Where do you get these 100mm injectors from? the bigger detroits?
Can you drop me a line man... Message me on here or I will give you my email address if you respond. Thanks man, I'd really like to hear from you.
+snoominati23...... Thanks for your questions. First, let me ask you a couple of questions... seriously. Your answers will give me better insight into the direction you should go with it, ok? 1.) How much money (approximately) have you allocated for the engine "build" ? How much (approximately) for the whole project ?
2.) Do you have a "source" for engine parts, or any idea at all, where to obtain them ??
I will tell you that.....
No, you cannot run the 2 cycle Detroits without the Roots Blowers... although there are alternatives which would yield higher air box pressures than the normal 4+ psi (other than by turbocharging).... but unless you are at least a "journeyman" class machinist, with access to lathes, milling machines, etc... or have the funding to buy your way through all the necessary work that would need to be done, then I would say.. forget it.
I have built one 12V71, that was putting out over 2,300 hp.... but, when your in the sport of Sled Pulling, you don't divulge "secrets..... and something tells me, that the cost of such an endeavor may well be, in excess of what you would be willing or able to spend.... besides the fact, that it would be totally unfeasible for use in a hwy truck..... and at those build levels, would be unreliable for any highway use.... not to mention the fact that you would be burning approximately 1.7+ gallons of fuel per mile... and that would be if did NOT "get into the pump" at all.... in other words, drive it very "gently".
Reply back to me, with honest answers to my Two questions at the top.... then, I can make some clear suggestions about which route you should go to help you obtain your goal and vision with this project. Thanks
do you have en email address I can contact you on? If you want mine, click into my profile, go to the 'about' option and send me a private message and I'll send you mine. Cheers, Tom.
Anyway, I just want to find the latest year model truck that would have been fitted with a 12V71 TTi . I want to uprate it as much as possible, with a "reliability mods" sort of outlook. but I do want the extra power and the revs. If I do bigger injectors and the timing mod, what sort of gains can I expect? Btw I was thinking, can the inlet ports in the liner be ported like a cylinder in a 2 stroke dirtbike for example? If you could modify them for longer duration or earlier opening, surely there are gains to be made there?
Nothing like the sound of a buzzing dozen!
Not only the great sound from a 12V Detroit but a great smooth driver with smooth shifts. How about another video Mike? We'll be waiting and thanks.
radioactivelarry.... was told that Mike is "no longer with us". : (
@@Romans--bo7br damn,cancer? I'm loosing friends regularly to it.
@@graham2631.... Hi Graham, thanks for your reply. To be honest, I don't know for sure... but heard that he died in an accident.. but Not in his truck (KW) while at work.
He only posted one other video around the same time as this one (just a short time after this video in the KW), showing his Boeing B-210 turbine engine he had on a test stand, which he started and ran for a few minutes in the video. That was the last we heard from Mike.
If I can find out for sure, what happened to him, I will post it on here in the comments. Thanks again, and take care.
@@Romans--bo7br he is very much still alive and well. Not sure where that information came from.
@@tylerbyman3258.... Tyler, Thank you for your reply. As I said in my comment/reply, above.. I could not verify whether what I was told, was correct, or not. If what you say is true, then that's Great news. So.. you Know Mike, personally? What is he doing these days?
damn i miss drivin! true professional behind the wheel Sir. smooth as glass.
The song of my people i am the last of three generations of truck drivers.
I had the "pleasure" of driving one in a Brockway early in my career. It was a bit tattered by the time it got to me and it broke down a bit with 570K on it. Whennit was running it sounded amazing
Nothing sounds better than a 2 cycle Detroit diesel! Thanks for the "symphony"!!
Peace and quiet does. Haha
I honestly dislike the way a detroit sounds.
@@andrewbowles923 And yet you took the time to watch and comment...smh
Drove hundreds of thousands with a 671. Same sound just half as SLOW
@@andrewnorris1514 half as slow? In other words twice as fast huh?
This is one of the most beautiful videos I have ever listened to in my life. I love it!
Thanks for the memories, Mike... I put well over 3 Million miles (total) on the 3 - 12V's I had... my first was a 69 Extended hood Pete, then 74 & 81 "A"'s like yours.... I love the sound of the Naturally Aspirated 12's like yours... but, I'm a huge "fanatic" of big muscle, so I "built" mine with Twin Turbo's, my 74 had 120mm White tags, the 69 had 100mm Green Tags, the 81 had 9290's & 2 degrees adv. timing, marine valve springs (to negate valve float).
Both KW's had DBL OO 6X4's and I set the wot no-load @ 2925 rpm - loaded would pull 2850 - 2900.. peak power for the 74 on the water brake dyno was at 2480 rpms @ full load, produced 643 hp (flywheel) with the turbos I had on it at the time & no inter or after cooling (on the dyno), but after cooling on the truck.. and 8" straights... Lots of fun... especially in the grades.
Fuel was cheaper back then.... though after the stupid feds deregulated us in 80 and just about every couch potato, wannabe went out a financed a truck and the rate cutting began.... the profit margin, nose dived considerably for many, as surely you must remember.... was tough sledding for a while for a lot of O/O's, but fortunately the over-dimensional heavy haul niche remained pretty well unscathed from all the idiots pulling boxes and flat beds.
Your video says "Part 1".... is there a "part 2" that we're missing somewhere??..... have been searching the net for it.
What camera were you using in this video??.... GREAT Sound reproduction !! Are you running the RTO 12513 behind her ?? Take good care, stay safe...... and NEVER, EVER sell that 12 !!!.... or, you'll regret it, like I have... Many times over !! : (
Hello Erik...
Just now revisited this video to recapture my memories.. : ) (5-31-2016) To answer your question... I actually put naturally aspirated in my initial comment, just as a matter of recognizing it for what is, through the sound of the exhaust and the engine itself.... Not to cause any armchair experts to debate me about it..... I could really care less what they think they know.
I have enough experience with the 2 cycle Detroits to know what I know..... between owning, operating and building my own DD's (and some for others... including One 6-71TI that dyno'd at 478 hp(!)..... and there was more where That came from. : )
I also spent 4yrs of formal study in Diesel Engine Design & Theory (specializing in 2 cycle).... 3 of those years, directly under the recently (in 1964) retired VP of R&D at GM Diesel (before the name was changed to DD in mid 1965).... so I received some real inside information on what can be done with these engines..... they will Really put out, if you understand them and know the structural limits of the metallurgy..... as with any engine.
Next to the 12V71.... my favorite(s) are in a dead tie for 2nd place.... the 6-71, the 6-110 and the 3-71. The 6-110 probably inches out the 6-71 for me, due to it's longer stroke and torque output and the ability to "hold" the torque with its increased stroke length (higher piston speed in the bore = equals greater inertia). I was privileged to see and witness (on the dyno) through my old instructor... a 6-71X (experimental).... an all aluminum block... with the dyno stopping the clock at 756 HP and 2750 rpms on the top end !!
Was involved with a V12 (71) used in the Pro - Semi Sled Pulls.... that was run at 4,000+.... and Never blew up in over 20yrs of competition.... and with a new owner, is still running !! Too many tricks to list... nor want to (re: secrets).... but output was over 2,300 hp... and around 3,000 ft lbs of torque.
As far as being the most power dense (output per lb of engine weight) of all the 2 cycle Detroits... the 6V53 is the winner....... I know of a Marine Detroit builder/rebuilder on the east coast, who, back in the late 70s & through early/mid 1980 was running a Rear Engine Dragster that was 6V53 powered.... well, actually it wasn't because he De-stroked it down to 270ci (verses the stock 318ci) and turning at 5,000.. twin turbo-chargers large injectors (and other tricks)..... was putting 1,000+ HP... to the ground (equated through his ET and Mph time slips)..... and That was BEFORE he put it on the bottle (nitrous, but don't remember if he also augmented with propane or not(?))..... = 1,500+ hp. Take Care.
Hello again Erik...
It's 8:50pm Mtn. time.... just got in.. busy day and need to shower and eat... but checked my mail and read yours... good to hear from you again.
Not sure if I'm up to a full response.. tonight yet.. will see what time it is after get cleaned up and eat... but wanted to at least let you know that I did receive and read you reply.... and will reply asap.. if not tonight.. then I will tomorrow at some point for sure. K?
Take care.
Hello Erik,
Thanks for your kind words, and your welcome.... but, I sure do Not claim to be an expert, and definitely Not the final word know it all, by any means... on the subject of Detroits... but I know enough to build them... well, I did... in my younger years, am retired now... but still in love with the 2 cycles, as it were... especially the 6 and 12-71, the 6-110 (NA & T), and the Series 149 .. never cared much for the 12-92.... as it is Not a TRUE V12 like the 71 was.... neither was the 12V53(T).
As I am typing this, I have my Bose headset plugged into my Bose System 5 with is wired in with my PC, and I am listening to Mike go through the gears with that sweet 12 just purrring away.... as Jackie Gleason would say...... Ohhhhh, How SaWEET it IS !!! : )
If you would like to hear what a 12V71 sounds like at 4,000+... do a search on Yt.... for... Lady Butterfly Pull Truck.... there are numerous videos of her at different pulls throughout the Ohio, PA, VT, NY, MN, VA, MD area over the years. You can't miss her... it's a 1974 Ext. Hood W923 KW... Yellow with Black fenders, frame, etc.... with two 7inch stacks coming right up the middle in front of the windshield. It was shortened up quite a bit from it's OTR years... originally had a 265 inch wheel base and a 6o inch, flat top sleeper.
You will notice a big box behind the cab, that slopes to the rear, it houses the radiator and valving for controlling the pressure on the rear driver when pulling the sled, and assorted plumbing. The compartment under the passenger side door... (originally where the batteries were located), is where our secret secondary fuel system was located... and is where 70 plus percent of the fuel flow comes from to feed the fuel faucets we had for injectors. : )
Both Turbos are from High Output, industrial 6V92's.... with two separate exhaust manifolds feeding each turbo..... yes, there are 4 exhaust manifolds on her, along with re-worked high by-pass blowers from 6V92TiB's.
Everything else done to it.... is a secret, and I cannot divulge anymore..... what I told you, is visible for anyone to see when the hood is up..... though, the old battery box cover was usually kept closed. ; )
Sold it last year to a new owner..... but, he has his daughter driving it (or did for the couple of pulls they attended at the end of the season..... and I think she is scared of it, because she is not getting after it at all. lol Not sure who is driving it this year, yet... if at all, will have to find out what is going on with it.
Just want to say that I agree with you on just about everything you say here.... the only thing to remember is that when we get hit with an EMP attack.... it WILL be lights out... for ALL things electric and electronic.... essentially it will instantly knock us back to the mid - 1800s.
It will do no good to have mechanical engines... unless you can steal enough fuel, because none of the fuel pumps will be working..... Nothing, electric or electronic will be functional.... Zip, Nada, nothing.
Is your 358A set up with sticks or was it modernized at some point with a single stick Fuller or Spicer ?
Is it sleeper equipped, or was it set up as a logger, or ???? Budds or dayton wheels ?.... if it was originally a logger, I would imagine it had Daytons on it... even on the west coast. Are you somewhere... out that way.. the west or north west ?
Well... I need to get to bed, and if I missed answering anything specific for you... forgive me, it's LATE (now), and I'm tired...... so, if I did.... please remind me, or ask anything you like... and I will surely answer you as best I can, if I can.... and If I don't know, I will say so.... K?
Have a good night, Erik.... take care til next time.
Hello again, Erik.... Sorry for the delay in replying, have been away for just over a month and just returned, late last night. I have a "ton" of things to get caught up on at the moment... but WILL write you back, ASAP in the next day or two. Take care.
You are absolutely right about the EMP... carburetors and mechanical fuel injected diesels will be the only things roaming the roads.
I’ve been over Satus Pass many a time,but I NEVER sounded this good! Gives me chills every time I hear it.
Old Man...... you would have Loved hearing mine pulling the grades to, then..... also an Ext. Hood A model, like Mikes.. here...... but my V12's were "built" to marine specs (minus the water cooled turbo's and exhaust manifolds), over 760hp to the ground... running through 7" pipes, and dbl Over 6X4 sticks.... with Up to, 2,850 rpms on tap if I wanted or needed them.
We turned 4,200+ with the 12 in the Super Semi class sled puller and putting out nearly 2,500 hp and 3,000 ft lbs of torque... for over 20 years, and never blew it up.... it's still running and pulling the sleds... though it's hard to compete against big inch 4 cycles (QSK Cummins' and E-9 Mack V8's) that are putting out 4,000+ hp and 5,000+ ft lbs of torque on the NTPA "hard tracks".... but we'd kill em on the softer sled tracks. You haven't heard music until you hear a 12V71 at 4,000 plus!!.... heck, even up over 2,350 and they Really start pulling.
A real Truck.
A timeless motor.
AReal Driver.
10-4 Driver.
They call me odd ball
When they ain't mad at me.
Nice rig excellent driver. Nothing sounds better than a Detroit in the hands of skilled driver. Please post more, I am a 30+ yr teamster side lined due to injury and this is how I pass my time god I miss driving. Thank you
ever thought about picking up a truck simulation game?
That sound gives me goose bumps best running engine of all time
the sound..............just glorious and sublime.
+wazza33racer for the first 5 minutes, yes!...
Screaming Demon such a lovely sound
I miss hearing these babies roll by my house on North Carefree out here in Colorado springs, Colorado. That and I use to live up by I-25 and I'd hear those classic trucks and trains roll by all night and the every so often jaking on the off ramps. That would put me to sleep or just hearing the clacking of the trains going by would do it to. I'm 19 by the way and I do miss these classic trucks.
Love this video...I've come to this a few times over the years just to take it all in. The drive, the sound, the scenery....Reminds me of a ride I had in Iowa with my uncle in his cabover Pete in '81. Wish I could do it again....
That old Detroit is doing what it was built to do... pull like a freight train and bark the whole time it's doing it. Much respect for the gear jammer behind the wheel. U can't ask for smoother shifts especially with one of the old crunchboxes behind that V12
Awesome sound ... I say that mostly from memory because I drove a 12V71 for thirteen years ... and I can't hear shit now except for that constant high frequency ringing in my ears.
Excellent driver, sooooo smooth
I. would. give. ANYTHING. for the experience of driving one of these two strokes for a day... GREAT SOUND!!!
I sure wish you could. You'd be one of those that nobody could knock the smile off your face. I'd love to do it again myself. I just lost a job....at 70. Goddamn insurance companies and not an "at fault" wreck in my history. I have no control of drivers running over me from behind.
@@oillease1881 I am really sorry to hear that. chin up, head forward. If God has it in the cards, you will be up and running again.
Thanks so much Mike . You were my dad for 17.54 . Many trips with my dad as a kid knowing them that was the best music ever . If i didnt know better id say God was only able to make me feel this content
I love that sound. Could listen to her all day.
Am back again i got Looney.taking driving lessons from stive wonder got old so i came here to hear that big chungus do its thang.. great video 👍👍👍👍
Real pleasure to go for a ride, thanks.
That's it! That's the sound I heard -- back in the day. Nice video, thanks for putting it up.
I could listen to that raspy buzz all day!
Very satisfying, brings back a lot of memories. Thank you!
Ole 12 V sounds sweet,and great shifting by the way.!!!
Very well driven , good video and sound of 2 stroke Detroit Diesel engine is amazing. Thank you
I know its a lot of work, but I love up and down shifting pulling a load and jaking. I grew up in a small town at the bottom of along hill. Id listen to the truck coming and going at night - it'd lull me to sleep.
Same here! I-71 was behind my house with a steep grade... We had no air conditioning and the highway noise put me right to sleep.....especially the trucks.
+Talisman1957 Did you bring Jeff with you? He needs this.
+Lewie McNeely , Jeff has his own video with a tanker fire truck with a 6-71 in it. You'll have to go back 2 or 3 years in his videos to see it.
I saw the one of the tanker with the Cummins. Maybe I need to poke around some more. Thanks #57! Maybe it's his old water truck you're thinking about. I know it's got a 6-71 that's about had the lick.
love that sound! now I'm ready for bed.
Love how the camera is mounted, perfect angle.👌🚛
Running through Yakima nation land! Gotta love old school trucks! Glad to see your keeping her on the road man!
Brings back old memories driving the v-12's White Freightliners with a 13 speed fuller.
Great sound when you were pulling a train hauling two 20ft containers with about 45,000 in each one grossing about 125.000
Sure does. Talk about slam your hand in the door before you go to work! I've been running CATs for the last few years, and can't think of hitting that magic 24k spot on the tach ever again. We had an 8v92 juiced up to a dyno'd 875 at the flywheel, in a 79 KW C/O. We called it the Screamer! Six inch straights, and you could hear it pulling a hill for a mile before you saw it.
Hitting that jakebrake , people can hear it for miles.That V-12 sounds great, the skillful driver makes it look easy , seinic route
thank you KW Mike very nice video love riding along with you you are a true professional driver and that 12 v sounds great the video was great to I could even hear the tires humming. I have had to turn in my keys after a injury that left me unable to drive, I truly miss it as you can imagine. thanks again your video is like being in the seat again for me I have pulled in that hill many times are their anymore videos
Mddlclss Wrkr.... I was told Mike is no longer "with us".... but have Not been able to verify that. He only ever posted 2 videos, the other was of a little Boeing turboshaft engine he had that was mounted on a wheeled frame that he fired up and ran for a little bit.
I really love the fact this guy knew how to drive this. just listen to the skill... into gear and just a pinch of throttle.. brrrrrr then into the dirty juice.. brrrrrUUUUUHHHHH just a beautiful sound
+gizmo98632
he doesn't rush the gearbox either, clutch down, out of gear, clutch up, bring up revs, clutch back down again, into gear, clutch back up. nice and gentle on the old girl.
+Xantec I agree fully.. he and this old lady had an understanding and got along very well.. gentle yes. this guy knows his stuff
Just for your information, sir.... Mike does Not use the clutch (except when stopped).... and I don't know what you mean by "he doesn't rush the gearbox......" (???) Apparently you've never run ANY of the 2 cycle Detroits.. and Why do I say that ??.... because if you had, you would know that with a. 18.7 : 1 cr you HAVE TO be FAST on the shift or you will miss it every time.... they decelerate Very Quickly... and Mike is Right On It.
You also need to remember (IF, your old enough to have ever known in the first place), that these (this vintage, anyway) were fully mechanical with NO DDEC yet... and we had a Very good "feel" for the engine and transmission(s) working together... and could "roll" the throttle very smoothly into the shifts, up and down..... all that, is "Lost" today, with these phony electronic engines they have now, along with the equally phony electro - mechanically (using electro servo motors at the clutch and shift tower) shifted "Manual" transmissions...that even actuate the clutch........ but, then again.... they suit today's so called "truck drivers".
Mike has had his KW for a Lonnnng time... and he's well "acquainted" with it and that 12..... just as I was with my two 12V71 powered KW's and one 12V71 powered 69 Pete (my first one).... except I built my 12's to "put out".... they were dyno'd at over twice the power of Mikes KW, here..... but this one is NA, mine were TTi's (but NOT from the factory) and all three were backed by Spicer dbl Over 6X4's.... and the gov. set for 2,850 loaded rpms.
You've (re:anyone) Never heard a 12 "sing" until you start reaching 2,400 and up.... with twin turbo's and Brute power !!..... makes "the hair stand up on the back of your neck" !!.... and got the job Done... easily.
PS:.... my reply is to "Xantec"... above. Just noticed that Yt doesn't automatically fill in the "screen name" of whoever your replying to.... will have to be more mindful of that in the future, I guess.
2Stroke Diesel Power you ain't kidding...... you try to double clutch on the drop pulling a good hill with a Jimmy you will be on the side starting all over...lol..... only thing that gets a downshift is you better be on it as soon as the rpm pulls down off the governor and float Straight into next gear putting it back on the governor
Grabbin gears like a total boss. Professional sir
musiclover11000- there are still real trucks and real truckers out.there- the man who posted this vid is one and so am I son. there are still a.lot.of us left. you are not looking hard enuff son. god bless.
Back in the day before truck driver schools you didn't have to look hard to find a good truck driver, that's the point !!
Reminds me of that '76 W-900 daddy taught me to drive with. I haven't seen that stretch road in many years. Daddy's truck had an 8V71 with a 15 speed. Let 'er talk.
I have heard 1 2 stroke Detroit in person, a 6V71 on an old military genset.....that noise was glorious, but I badly want to hear 8V and 12V Detroits in person!
Wow just glorious. Its so powerful yet soothing.
The fuel mileage on the 12V71 is about 4 miles to the gallon if you can keep your foot out of it.
Absolutely fantastic! Keep on trucking Mike
Either blowing smoke or going broke
Nice sound🎶🎶🎶🎶
The days of turning wrenches and test driving these just rings loudly. Hope heaven is this way !
love the tug boat engine in a kw . back in the day a company named Levitz in Medford Or. had boat engine fr8liners. the would litterally fly up the Siskiyou pass. now watching a 12v pass you is a powerless feeling.
11 y/o son walks by and hears this.. yep that a 2stroke Detroit. Can't let them forget !
I've been waiting for part 2 for nine years.
Good Job, there is nothing better then a 12-V71 or 12V-92 Detroit Diesel kicking some Ass out on the road! I spent a lot of hours with my 1970 Freightliner that was nothing but fun, no break downs, leaks, or problems. I twisted mine up to 2700 rpm, worked at 19 to 2200 rpm made some good money!
Virian Bouze..... you mentioned both the 12V71 and the 12V92 and that you "spent lots of hours with your 1970 Freightliner, etc, etc, etc.... which engine did you have in your Freightliner?... you didn't say which one. What did you do to turn it up to 2700 rpm and not have any "issues"? Why bother turn it up to "2700" and yet only work it between "19 to 2200 rpms"?
Man that’s gonna stick in my head all night
Thanks so much, It brings back so many memories. I loved Detroits....and still do. If'n you need an operator and not a steering wheel holder, holler at me.
Oil Lease.... Mike won't be able to "holler at you".... he's "no longer with us", I've been told.
@@Romans--bo7br I'm sorry to hear that. Hope he went easy. Don't know why I'm still here. Seems the last couple years have been like that. Like Hank said I'll never get out of this world alive but never figured for so many to beat me.
I've noticed so many times some thing is still fine and outlives it's creator.
Thanks for the info. I'll say a prayer for him. peace b
That's good shit right there, Nothing like the sound of TWO STROKE pulling !
super smooth shifting
thanks for the ride along!
Aaaaa yea talk to me i got the cops called on me because of the sound of this truck i had it truned up on a sound system man sound good my neighbors dint thank so f...um I like it ..👍👍👍👍👍great video
Sounds wonderful.
I never got to drive or ride in V12 but it really sounds more like a 6n71 than a V8. Great video miss riding in the old Detroits back when I was a kid.
Hello Robert..
I was fortunate enough to not only "ride" in GM Diesel (as it was known as, from 1938 to mid-1965) powered trucks as a kid... I also studied 2 cycle diesel (GM/DD) design, directly under the, then recently retired (in 1963) VP of R & D at GM Diesel for 4 years... and later, owned and "built" (modified the engines from the "ground -up") 3 semis (a 69 extended hood Pete, and 2 ext. hood "A" model KW's), that were all (modified)12V71 powered... over the years of trucking as an independent Owner Operator (had my own authority).
The 12V71 is the ONLY "True" V12 that GM Diesel/Detroit Diesel ever "clean sheeted" and built... with a true V12 firing order (actually they utilized two different firing orders, depending on rotation)... unlike the 12-53 and the 12-92's which were (in reality) two separate 6V's that were assembled in "modular form" with redundancy of all systems except for the governor.
Same as with the 16, 24 and (special order)32V71's.... the 12, 16 and 20V92's... and the 12V53 (only 8 were ever produced)..... they were purposely designed so that all they had to do was add different numbers of cylinder configurations to achieve whatever power levels were required, without having to "clean sheet" a whole new engine design every time power requirements demanded it..... very ingenious, to say the least.
But as far as your comment that "it really sounds more like a 6-71N than a V8"..... I don't understand. It sounds exactly like what it IS...... a 12V71N..... and why would it sound like a "V8" (8V71N ?) at all ??.... you've got 4 more cylinders and a completely different firing order. The same goes for the 6 (either the 6L or the 6V).... they sure do not sound like the 12 and the 12 does not sound like the 6 at all.
Where I would agree with you is..... If you were comparing the "12V92" ... to the 6V92, Then.. you would have a valid point..... Why?...... because, as I pointed out above... the 12V92 is made up of TWO separate 6V92's that are joined at the crank with a coupler and the blocks are joined together via internal fasteners and a "common" oil pan.
That is why you see 4 heads and valve covers on the 16 and 24V71's, and the 12 and 16V92's... because "you" have 2 completely separate engines, set up in modular form to produce a "V12 or V16".... and each has it's own firing order for the amount of cylinders in that block (either 6 or 8).... which is why a (ie:) 12V92 Really sounds like a Really "big" 6V92.... because all you really have is two separate V6's running in unison together... and it wouldn't matter whether they were mounted in "tandem" (as they are), or mounted as "twins" (side by side)... just like they use to do with the 4 and 6-71's (even mounted in Quads) before they came out with the V configuration engines in 1957.
Take Care.
My Dad had 6n71's from 218 to 238's as I was younger. When this driver would downshift I nearly shed a tear. The music was beautiful.
V12 do sound like Inline 6s. This is because the firing order is often 153624 on each bank.
I don't think these sound like a V6, but the big advantage of V12s is the double 6 firing order indicating perfect natural balance and no secondary vibration. The design also benefits from the lack of large crankshaft counterweights.
Nothing beats the sound of the 2 stroke Detroits; music to the ears
I could tell every time you hit 2100 those v12’s get that awesome buzzing resonance, love it.
J.R. In WV.... You should hear one at 2,700+ pulling 118,000 lbs (Super "B" doubles) up a 6.5% grade.... twin turbo'd, High Bypass blowers, 7075 injectors, marine springs, etc, etc and w/2 degrees adv. timing (843hp on the dyno at 2,480 rpm under full loading). PS; Yes... it was one of mine, back in the 1970s.... a 1976 KW 923 (ext. hood - "A" model), with Spicer dbl Over 6X4 sticks.... completely beyond the comprehension of today's "steering wheel holders".
2Stroke Diesel Power I sure would have liked to hear/see that. You probably had to be pretty good not to tear that 6x4 out with that kind of power, you know.... ease off the fuel until the driveline unloads, slide her in the next hole and come back in easy on the power. most “drivers” today would probably have it torn out in a day.
2Stroke Diesel Power what rating were the 7075 injectors, I’ve seen a lot of n70’s in the n/a 8v71’s and 435 horse 12v71’s, would a 7075 be 75 lbs per hr or 175? either way, what a monster!
I want one! :) Hell.....this give me goosebumps! :)
Really would love to hear that when it get's to pull really hard!
Man u shifted like a pro love the sound i like to be with u have a good run over and out ❤❤❤😊😊😊 thanks for posting ❤ 😊!!++
Ahhh, the old screamin' Mimi!
Remember many a bus and fire truck with the Detroits; damn shame I never got to drive one.
That is just the way it shuld be ......not these "fleet trucks " of today that's back wen trucking was cool
"David Mccully"...... when trucking was Not ONLY "cool"...... but, was actually a very Respected profession, by nearly Everyone.... even the media and the "early" DOT people (after the ICC was first dis-banded by Washington)..... and I got to live the last of those "glory" years of trucking as an Independent Owner Operator (with my own ICC approved operating authority for reefers, flatbeds, end dumps (bulk commodity), and heavy haul)..... before they "de-regulated" trucking.... and totally destroyed it.... by opening the door for every joe blow shmuck who could get a loan and thought it would be "cool" to drive a "big truck".... and started hauling loads for "less than break even rates".
The "rate wars" wound up putting a LOT of established owner operators, family fleets and small companies that had been around since they first started building "trucks"...... out of business.
Before De-regulation started in 1981(?... or 80 ? I forget now... been a while).... produce hauling was Strickly the domain of owner - operators (with their own authority.... unlike today's phony "lease to own" (re: suckers, for the most part) "owner operators" running on their corporate owners authority), and SMALL family owned Owner-Operator "fleets".... which usually consisted of 8 trucks (semis/reefers) or Less.... generally, just 3 or 4.
Getting off on a rabbit trail here...... just memories.
Take Care.
Deregulated in 1980-- thank you, Jimmy Carter...
what a great time in truckin
Reminds me of my father. Australian SAR although his was 6V92. We didn’t talk much.
Sweet tune you are playing there brother. you can drive thru my neighborhood playing that anytime
Nice run.
Wow very impressive 👍
simplemente espectacular!!!! saludos desde Argentina
I for got to tell u post more I love 💘 ❤it love that sound ❤❤❤!!++
Good Pull!
When I was a "kid" (1949-'55) I loved spending time at my gramma's house during the Summer. She was in sight of the the Nisqually Hill on US-99 (South of Tacoma, WA and Fort Lewis a "few" miles.) I'd listen to the big KW's with their "Jimmies" in high revs going up the hill and Jake's barking coming down. Sweet music! US-99 is now WA State 99 I think and Nisqually Hill is bypassed by I-5 so it doesn't get much OTR traffic any more. I-5 doesn't have much of a grade so the great sound effects are rare!
Guru Kahuna.... That's really "interesting", seeing as how "Jake brakes" weren't even around until late 1961... for the Cummins NH series engines first... as the "jake brake" was actually made feasible by none other than Clessie Cummins, himself.
It was Jacobs Manufacturing Co. that made the decision in 1960 to open up the "Clessie L. Cummins Division" (as a result of a "blind date" between Don Cummins (Clessie's nephew) and Roberta Englund whose father, Bob.. was VP of Jacobs Manufacturing) under contract with Clessie Cummins (this after he had sold the company and retired in Saucalito, CA.) to begin production of the engine brake that Clessie had developed, after nearly losing his life coming down the Cajon Pass to San Bernadino in 1931 (August, I think) during a "speed run" from NY. to LA. while attempting to set a new, diesel powered truck continental speed record, but it wasn't until 1955 that Clessie started to really "look into" building a viable "engine brake.... and as it turned out, Cummins and GM Diesels (Detroit Diesel after 1965) were "naturals" for the end design, as they both had "3rd" lobes on their camshafts that could be used to actuate a secondary exhaust opening.... but it was Jacobs Manufacturing that went "one better" and further redesigned it (still under license from Cummins) to utilize an electric over hydraulic system using the engine's own oil.
The first Jakes on GM Diesels came after the Cummins versions, in 1962.
PS: Part of the reason for Jacob Mfg's. involvment... was the fact that after Clessie's showing his invention to Cummins (first - as per agreement at sale of C. L. Cummins Diesel), Cummins Engine actually turned it down, as being commercially "non - viable" !!!..... brilliant foresight on Cummins Diesel's part.
2Stroke Diesel Power They finally made them for the 3406. I had an 1985 Freightliner cabover with an "a" and a 1988 379 with a "b", both has a Jake. Now if Jake's were operated off the injector lobe of the cam, how do they work on a Cat?
AHHHHHH the sound of my people! The old Buzzin Dozen.
Sick rig
Saw that down hill sharp decent, damn hope the Jakes work, camera angle perfect, I felt my arm reaching for a quick down shift.
damn nice ride man
I had 4 of these k w s healed all over weight over with load aaaa the MEMORIES
I like to run no load for 30s before engaging the Jacobs so the valves have a chance to cool down a bit. I had to swap out a set of valves on one cylinder and it was the hottest running cylinder on that side
Love it.
good music for me on ride :)
