The Cat 3406 has provided for this family and still has for decades. The best engine ever made for heavy haul.
Big Jimmy diesel won't run with out a blower
None of the two stroke Detroit's are particularly rare or valuable. I see them on the road daily here in the rural great lakes region. They are some of the best damn diesel engines ever built. They are als not supercharged. That is a roots blower not a supercharger it does not make a single pound of boost. It is there simply to move the exhaust out of the cylinders and pull in air under vacuum called scavenging. A 2 stroke Detroit Diesel has no intake valves and therefore like other two stroke diesels it needs the blower or it will not run. These engines came out in the late 1930' and at some point hot rodders figured out they could use the blower off of the six cylinder engines as a supercharger even though it was never designed for that purpose. That's why to this day roots superchargers while they may look cooler are nowhere near as efficient as centrifugal superchargers like the Paxton and Pro Charger designs.
I saw LOTS of Mack trucks in Wisconsin while growing up there in the 1950's & 1960's. Once I got out to California while in the Navy I hardly saw any. Now that we've moved to southern Idaho we see a lot more of them.
The Detroit two-strokes did not use the blower/supercharger as a power-adder, it was needed to run.
The air box needs to be pressurized to force the exhaust out through the exhaust valves in the cylinder heads.
Correct your statements please
Note...
The supercharger on the two stroke Detroit engines don't add performance. The supercharger is required to give the engine enough air to run at all. Two stroke diesels can't suck air, so without the supercharger, the engine can't run. I drove an old Kenworth that had an 8v92 that someone installed twin turbos that fed compressed air into the supercharger. The turbos added the extra air for better performance. Not the supercharger.
The HP specs are a bit off when you take into consideration that Mack rates HP at the ground,,Cat rates HP at the wheels, Cummins rates it at the flywheel and Detroit rates it at the crankshaft
Finally a video without AI
The narration is most definitely AI. Listen to it and you can tell. Normal people won't say "Cummins eight hundred fifty five". It's the eight fifty five Cummins. Peterbuild three hundred fifty nine? Nope, three fifty nine. That's how people talk. This is AI.
The best truck engine is the 14 litre Scania.
BS video ,,AGAIN THESE ARE NOT RARE ,JUST OLD,DROVE MANY DETROIT DEISEL 6V71,,8V71, 6V92 ,,8V92 , 12 V 71, NOT RARE AT ALL
That's what I was thinking I see Detroit 2 strokes on the road every day. Though the 12v71's are getting pretty hard to find. And all these dumbass kids like kT3406E blowing them up for fun on RUclips. I'd kick that kids teeth in if I met him. Stupid hillbilly farmer things he's a bad ass. He's as big a bitch as whistlin' diesel. Got daddies money and feels special.
Your information is very flawed if you cant do the research you shouldnt post it
I second that.
I think he's confusing gas engines with diesel engines as evidenced by his mentioning of the supercharger on a two stroke diesel providing extra air to the engine. He doesn't know that a two stroke diesel can't even run without the supercharger.
He also seems to be confusing, at least partially, the 3208 with the 3408. The 3208 does work in medium duty trucks, but in a class 8 truck, it would need at least 25 gears to get the truck to move with a full load.
He also seems to be unable to read a calendar as some of the trucks mentioned didn't exist in the 70's. And his mentioning of a series 60 adds to the evidence of his inability to read a calendar.
It would be more interesting to be sitting at the counter of a truck stop listening to some Bozo talking about how his car can pull a fully loaded semi trailer. I'd be impressed if I stepped outside for a smoke and saw a '73 Cadillac with a 7x3 pair of boxes and a pintle hook as, by golly, it could🤣
The 3406 b and a in the 70s were 14.6 liter in 2005 when Cat introduced the acert 3406 family which was known as C15 acert it was 15.3 liter because they changed the stroke .
Are you serious? You talk about all of these “rare” diesel engines but fail to even mention the 903 cubic inch Cummins V8? What the heck you been smoking man?
Thumbnail states 20 rarest not 20 most common which is pretty much what you have based your information on
The 478 in the GMC Brigadier was a V6 not a V8.
Never let the facts get in the way of a good tall story eh !
Cummins L10 capacity of 8.3 litres, believe it or not !
Your a fool. I rebuilt an L10 in high school right on the cover of the service manual it says "displacement 10 liters" I'm looking at one of those service manuals now.
I won't say that the cat 3406 was a bad engine, it wasn't. Every engine is going to wear out. Through the 80s and 90s i could rebuild 2 Cummins or 3 e6 series macks for about the same cost of 1 cat!
Cost doesn't have anything to do with price. The shop I work for runs 3406B's in all our heavy wreckers. We can inframe a 3406 in house for half what it cost to do an 855 Cummins.
I drove a international cabover in the early 70s with the 8v71. Probably the worse truck i ever drove! I carried a spare piston, liner,rod bearing and gasket set under the bunk, I was running between Omaha and Chicago and put pistons in that Detroit in every truck stop and rest stop on that route!
Youre a lying sack of shit. One man can't even pick up the head on an 8v71 and you have to pull the head to change the piston/sleeve. Those 2 stroke Detroits are probably the strongest most dependable diesel engine ever made. There's a reson they made them from `1938 until 1993. You might have had a shop changing a cylinder that often if there was something wrong with it. But as a diesel tech I can think of nothing that would cause the same cylinder to go every few thousand miles. Oh and another way I know your lying besides the fact that replacing the whole power assembly would cure any issues and the fact that you can't lift a Detroit head by yourself? Detroit 2 strokes don't have head gbaskets! The head and block are machined so perfectly flat they don't need them. Guarantee that as many Cummins 855's and CAT 3406's as there are on the road today there are over twice as many Detroit 2 strokes.
You did not include some of the best truck engines ever, notably the Mercedes-Benz 4,6 and V8 diesels of the 1960's to 1990's also M.A.N and Magirus-Deutz diesels of the same era. The Magirus-Deutz were aircooled diesels and were in my opinion the best engines ever.☘
Those engines were not popular or even available in the U.S. Also European diesels of that time were nowhere near as good as American stuff. You can run a Cummins, CAT, Detroit, or Mack over a million miles between overhauls. Try that with a 60's or 70's Euro diesel that makes nowhere near the power. In the late 60's Cummins KTTA's and Detroit 12v71's were pushing 600hp. Euro diesels while they may be the most powerful truck engines in the world today were nowhere near that until the 1990's. But Euro trucking is totally different, our weight limit here on highways is less than half what most of Europe is. Hence the need now for those bigger more powerful diesels.
@@outspokengeniusworld is bigger than murica
The 60 Series Detroit was not rare and was made until 2011 neither was the 3406 Cat made in one form or another till 1999, most of the engines mentioned in this video were not rare. The title should have been the most popular engines. Some of the trucks shown like the freightliner fld wasn't even made till the late 80's but what do you expect from a Bot video LOL
a supercharged 8v71 detroit? u really need to read up on how the old detroits worked.
You're correct, sir. And the 8v71 is naturally aspirated. They did offer a turbo later.
3208 were (throw away engines).
Simply too frustrating listening to "AI" attempt to pronounce those displacements!!
Why not add the IH 6 cyl gas engines of about 500 CI, and Ford's super duty 534 and 477 gas V-8's. And get a human being to do the narration.
Stop using AI. Do your research and present the content yourself. And none of these engines are rare. They were all common in their day.
Ahh an 8V92 with 892 cu in. Proves either A I hasn't a clue or who ever wrote the script for the A I voice to read has not figured out math. 8 X 92 = 736 cubic inches or 12 liters not 892. Also an NTA 855 Cummins did not produce 1750 ft lbs in a 400 hp. They were rated a 1200 ft lbs. An N14 855 will produce 1750 ft lbs in the 500 to 525 models. LOL a Cat three thousand four hundred and six oh my God.
