HuH? what did you say? I owe a lot of my hearing loss to sitting on top of those screamers in cab over Fords. All day long hitting gears picking up trash. they would always start and were always loud. Must be why I have one in my dump truck. HuH?

death of the detroit diesel 2 stroke
In the lates 80`s the engine makers saw the writing on the wall
about the coming snog and pollution rules for diesels. There
is no way a 2 stroke diesel could ever meet these rules. So they
phased out the 53 and 71 series engines. Also about the time GM sold off
detroit diesel. Despite all the great lore about these engines. They had there
faults. 1. not much torque as compared to a cat,mack or cummins engine 2.
They would as my dad put it slober oil a low idle. 3. And yes they were
loud but not in a good way if there is one. The sound they made would drive a man crazy after while. :Banghead It was so high pitched!
But in there defense they were cheaper compared to other engines and they were simple to work on and the parts were cheap and easy to get.

any diesel shouldn't idle ,with the jimmy it was oil and fuel ..on the for stroke fuel loading into the exhaust ...any Diesel well get rotten if idling for extended periods
The oil they let off at idle was due in part to poor scavenging in the cycle..they all load up ... they used more fuel ..twice as many power strokes over a four stroke.....
Emissions ,fuel efficiency and in some small part the need for quieter running Diesel as noise pollution became a bit of an issue back in the 80's

A place where the Detroit still lives on...
I can't say all their trucks do, but all of the Fire Trucks I've heard from the Knoxville Fire Dept still use the Detroit 8V-92T. I was sittin' on the couch today viewing HEF when I heard the Federal siren coming down my street and stop 3 houses down. It seemed one of my neighbors caught his mattress on fire. He wasn't hurt, and the KFD quick response got it out. Company 11 engine showed up first, within minutes Company 15 engine and ladder showed up. You could here those 92's hummin' before they even turned on my street, music to my ears.

We've got a 6V92TA in two of our trucks, I think they were bought in '96 and '97. The two newr trucks have the Series 60 in them.
When I was a kid, the largest town in the area had a Seagrave ladder truck with an 8V71 in it. Their firehouse was 13 miles away, but if the wind was right I could hear them pull out responding to an alarm.

Part of that is actually false. A mechanical 2-stroke detroit can and has met tier II & III emissions. So if anybody has the smog police after them for their detroit let me point you in the right direction. The proof http://www.arb.ca.gov/eqpr/kits/ccts/ccts.htm
The Place http://www.cctskit.com/
The real question is why the hell detroit dropped the 2-strokes in favor of 4-strokes just to have some private company show them up with technology. They spent millions on computer programs to clean them up and never could get it to work. This is the best example of KISS I have every seen. To my knowledge the only mechanical engine to meet emissions.
The noise is just a matter of opinion. If you don't like it get a better muffler.

I'm still livin' your childhood, Steve. Fire company 11 is just about a mile and a half from my house, one of the reasons I bought this house. In Knoxville, the fire dept has the duty of being "first responders" on any 911 emergency call. Car wreck, heart attack at home, anything that's an emergency. I sit here many times and here that engine going in various directions around me, you can hear that 92T humming for miles with that siren wailing. The 92T is one sweet sounding engine when they're stepping on it to answer a call.

The fire company here has an Oshkosh four wheel drive airport crash truck with a 8v92 in it.Rear mounted on basically a sraight pipe.It's cool to see/hear it on the road.They hook it up to hydrant when training and or testing the pumps and just hold it wide open throttle-for minutes at a time:drinkup

when my uncle taught me to drive a truck it was a 1974 freightliner with a 350 detroit the part of slobering out oil was true if under1000 rpm's i hauled lumber and wood chips in the mtn's of western n.c. with it and when you got with in seein distance of a good hill the engine could smell it and start lugging down lol. some yrs. later i drove a lnternational 4300 with a v12 it had enough power you could go through the bottom 4 of a 13 speed and get on it real good and break the yoke at the rear end the v 12 had some power but they did lose some oil i had a guy tell me 1 time that when they shiped them in a crate they showed up 1 gallon low.

You will still find a lot of 6-71s in older boats. I have a pair of 6-71 TIs making 410 horses each in my Gulfstar. I get many comments on how nice they sound as I am coming in or leaving my slip.
(I know, it's not heavy equipment, but Detroit 2 strokes have a big marine following too!)

How do you get 410hp out of a 6/71? That's almost double the factory rating. How long does the engine last at that rate?

If you will notice most marine applications can be rated near double what it would be for anything that is on the ground. Part of it is almost unlimited cooling that is available from the sea. Of course they don't last that long rated so high, but while they are running they really run.

Unlimited cooling and that they never lug or are shock loaded lets them live at high hp settings. Not only Detroits, but any diesel. I saw a pair of marine 3208's at the Cat house years ago that were 425 apiece, incredible as that may sound. For an example of a current engine, the QSC 8.3L Cummins is rated up to 600hp for recreational marine.

I think marinized 3208 cats can be rated over 500hp!! The highest rated detroit that I know of is a racing 8v96 (not a typo) 1775hp, in stock and ready to rock for $75k. This is the shop that it was built in http://www.jackbivens.com/ talk about a screamin' jimmy!!

My grandpa was a HUGE Detroit fan. I think he ought things just because that is what powered it. I can think of @ 7 238's that are still hanging around.
Dad later bought a old state truck with a 6v ? in it. I was working for a guy that lived about 3 miles from dads house. Anyhow, I heard it screaming one day, I told the boss that dad would be by shortly.
He asked how I knew?
I can hear him, he just left the house.
Bull----
wanna bet?
$50
ok
Here comes dad, pay up!!!!!!
