I've got a 6v92 in a dump truck and she runs mighty fine weighing 60000. Might not get to 65 as fast as some others, but she maintains well once rolling and her turbo is piercing your eardrums
@@chuckg2016 Only 2 stroke I can get here in Europe is a motorcycle or a Trabant :D so I have 1984 moped Babetta 210, 50cc two stroke, Vmax in papers is 45km/h on the original gear 13/51..... I had general repair done on the engine and gearbox (yes, moped with 2 speed automatic gearbox) few weeks ago, it has fresh 85km on new, but it goes 55km/h, engine isn´t really run-in now, but I have fucking overtaken Audi A8 in village :D :D It is recommended to not pull more than 3/4 gas and not to drive more than 35km/h when engine is running-in, but fuck it, full gas and it went crazy :D :D Two stroke is fun even in a few cubic centimeters..... Before general repair it went 65km/h after the wind..
@Peter Szoke Detroit Diesel had various models of their two-strokes running in truck frames. I'm of the opinion that two-strokes are great engines in industrial applications like electric generators, agricultural pumps, etc., but for pulling loads I want the low end torque of a four-stroke.
@@chuckg2016 Yep, thats true my friend, four stroke has its peak torque in less RPMs than two stroke has.... But there must have been a reason to make 2 stroke diesel... Idk, maybe less requirements needed to make a 2 stroke :D
I drove one of these long enough to know if he had any load worth mentioning, he couldn't have skipped gears and picked up speed like that! I'd dare say he was bone-dry empty. Love them Detroits, though.
Only gears you skip loaded, is downshifting. Max load, throttle should be a toggle switch. Cool video! Like WATCHING videos on the Green Weinies, never want to participate. They'll definitely teach you to shift, cause that's all you do.
Oh, man! So much fun! My first driving job back in the ‘70s was for a family-owned lumber company located in the Adirondack high peaks region in upstate New York. They were soup to nuts. Everything from logging their own land, to milling and planing lumber to operating a full-service home center. I hauled pulp wood, wood chips finished lumber. Back hauled all manner of building materials, from shingles to cinderblocks. Most always wa-a-ay over weight. A 350 Cummins was “big power” for us. Hauled some hellacious big loads over hilly secondary roads, 10-12% grades not uncommon. Often in a Fleetstar 2070 daycab International with a 290 Cummins and a 13 speed. Jake brake? Never heard of it. Had a ball. Went on from that to hauling chemical tanker all over the Northeast. My one big regret: I never got to drive a 2 stroke Detroit
It sounds happy... Detroit's love to rip.i had a 453T in a 65 Suburban..bought it that way. 3500 rpms sounded like 8000. Love that 2 stroke death sound. I may have only had 150 HP..but she sounded so goooood
When I was younger, I always wanted to drive trucks.My friend taught me on a 4000 c.o.e. International with an 8V-71. Just keep it wound up he would tell me. He also was a good mechanic and fixed cars and heavy trucks with his older brother when they had a service station.I used to go to their station after working at my factory job, to see what trucks they were or had worked on. One day they had a Diamond-Reo tandem axle flatbed with a 6V-53 that they had finished repairing. My friend let me drive it back to the customers yard .It had a 10 speed and what a screamer it was! That was the end of my driving dream as I got sick. I still liked trucks and heavy equipment and learned a lot about what it takes to fix them.
Love me some Detroit Diesels so American so wonderful no engine in the world sounds as good as loaded Detroit with the turbo screaming! Wow this old girl is in fine shape. Always did love the General I feel if GMC went back to those days what comes out of Detroit today would make us PROUD like the ole General still does! Keep windin so never forget.
The 6v192 work amazing when you power shift or float the gears. My dad had a 28 bale chain driven hay truck that had the same motor. It had several auxiliary transmissions but that thing purred like a kitten with the right person driving it.
1975 GMC Diesel 70...6V92...80,000 pounds of steel pipe from Gardena Ca to San Diego Ca...south bound 805 hill..10 MPH by the time you got to the top of the hill...tried to blow it up it she kept on runnin...lol...did use a gallon of oil every run....this was in the early 80’s...
Watching this makes me sure my memory still works am only radios of the day were on ceiling so you could almost hear it at full volume rolling on the high side lol the air wipers almost forgot them gems after seeing this I suppose I’ll wake in a cold sweat dreaming about those days wing vents were nice still miss the sound Though Would keep you awake all night b4. Cb’s stereos and fm satellite Driver knows how to run it 4sure
Look closer Rain Coast, there's a yellow trailer behind the dump, and it's a 2 stroke diesel so it doesn't have to be running high rpm to sound like it.
I envy you guys being able to sample 2-stroke V6's - little like that to hear over here in UK whatever the criticisms. I enjoyed listening to it. Did strike me from the gear changes that some gear skipping was taking place as the revvs dropped but always understood you wind a 2-stroke up to the max to compensate on flatter torque response from them and lots more gear usage, compare to say a UK slow-revving 4-stroke Gardner. Tony.
@@mrobinson4210 the engine in this video was a V6; it was the DD 6V92. The 6 denotes the number of cylinders; the V means it's in a V configuration; and the 92 means there's 92 cu. in. per cylinder. The 6V71 was a popular DD two stroke back in the day, as many city buses had them.
@ktumble moving the pedal just helps get the timing for some. I only ever moved it in the free play. Ceramic clutch in mine with the brake at the bottom of the pedal.. Straight cut gears, mine would fall into gear no issues
You really only need to double clutch for down shifting, and that's only to get the counter shaft gears spinning as fast as the main shaft. For up shifting most drivers, especially the old school ones won't use the clutch. Mack trucks owners manual from the 50s say that once the truck is in motion it's not necessary to use the clutch for up or down shifting. But you should always drive a vehicle which ever way you feel comfortable doing so. So hammer down.
Roadranger? An 8 speed? That's what the shift pattern looked like! But if that was a 10 speed RR, you should be able to run up through the gears with your foot off the clutch, with less drop in rpm's! But it sounds empty!
I remember the first time I drove a 6V92 Detroit in an old international. I couldn’t get it to shift for nothing. Then I was told runner up to about 1800 or so RPM. Then it shifted fine.
There’s only one way to drive YOUR OWN TRUCK, the way you see fit,, everyone is an Authority or professional on you tube. I get a kick out of the comments, and my comment could be viewed the same. But when it comes down to it, it doesn’t matter at all. I just say to anyone making these videos, of any kind, keep them coming. I love it . It’s like baiting the hook and see who hits it. All the rights and wrongs in different people’s eyes. My Daddy did it this way kinda stuff. And if you respect your parents and they did anything the right way or wrong, it is right to you. Now for my opinion, and it is only opinion,, from my point of view. My daddy double clutched every thing. Until he had a knee replacement on his left leg. Doctor said it was from constantly over using his left leg every day, I have seen transmissions and clutches used by both. And the guys that double clutch, thinks it’s normal to replace a clutch regularity. As for me, I do my own repairs , and I don’t like working on stuff I can prolong, like clutches. I have been driving for a long time and like others I have my opinion. I can double clutch also, but it my opinion, WHY but that’s me. Is it right or wrong? Any way enough rambling on, I do it because it is YOU TUBE, and it don’t matter anyway.
They were lower gears so your point? Drove many 2 stroke Detroit's in my younger years and did that all the time. I drove an '89 6v92 a LOT that had the electronic computer/throttle. Couldn't make it smoke and you could lug it all day long at 80k with no harm.
diesel mutt88 what little experience I have with one, I would put money on the table to bet he wasn’t too heavy. I can’t skip shift loaded with the truck I have now and it certainly has more power than a 318. I can’t believe that you had a Detroit that didn’t smoke? I believe all the two stroke v8’s they made, smoke like hell under load or heavy throttle? We have the very same truck as this video and it has 3.90’s with a 13 speed. No way on earth does he have a heavy load.

They were tuff trucks, all steel dash board, zero sound insulation, only competitor price wise was a Ford Louisville. We owned a 1984 Brigadier with the 6/92T Silver super reliable power and never failed to start no matter how cold outside it got, it had dual block heaters and a big oil pan heater. It'd fire up like summer at 45 below, also had an alcohol sniffer on the air system, and it never had air brake freeze ups. Good ole truck but deafening to drive.
I drove a 10 speed in several trucks for over 10 years and you don't skip shift like that with a load on. Plus you have to keep a GMC up against the governor to get anyplace. This is a totally the way he said he had a wood chipper and a load of logs. Come on guy who do you think you are fooling. Plus you never use the clutch to shift only to start the truck moving! If you can' shift a 10 speed without clutching you are not a truck driver !!
If you knew anything about floating the gears, you would know that the shift is made with the gears unloaded. Going uphill at speeds under 10 mph , short precise shifts must be made and there is no time to double clutch between gears. Either master the technique or stay in 1L till you crest the hill.
@@richardmaurer9002 Thanks Richard, yes I do know what you have mentioned. Drove a 15 speed for many years. Not sure if you know how steep and tight some of the roads in New Zealand 40 years ago but if you were down in low there was no place else to go except stay till the crest. Some places I went it was better to stop and start off in deep reduction. I did float in hi range every know and then. Regards Steve.
Any trucker knows you don't use the clutch after your moving. If he would have had a full load on going up hill, as slow as he shifted he would have been rolling back wards. You can not over rev any diesel motor if the governor is set right. I love the Detroit 2 cycle motor, music to my ears. The 2 cycle Detroit has to be run up against the governor to have any power.
