You can't have a Big Rig forum without some discussion of everyone's favorite diesel engine! SARCASM

 

I think "everyones" favorite is a bit much. The 2 strokes are by far the best at turning diesel into noise. 200 hp and 5 ft lbs of torque.

Everyone knows Diesel engines are like Bananas, They aren't any good until they turn yellow.

 

It's hard to be sarcastic while typing!

 

yellow nice but i still prefer a red top

 

Now that's a true enough statement.

 

You guys are way wrong. The silver 92's made 475-500 hp and 10#'s tq.



Yellow was the way to go until the accerts, then it was a crap shoot.

LOL. Now that's just plain funny. I never drove an 8 but our engine company was a 6V92 T/A. Wasn't all that great although it would eat up the 8V71 I drove in the truck.

 

anyone care to explain to me why these motors didnt make power? big turbos and blowers with twice as many power strokes as a 4 stroke.... please explain

 

But what sweet noise it is!

 

Because of the need to scavenge the cylinder. You see the piston was coming up but the port is open quite a ways up the cylinder before it started to compress the air. They needed the blower to clear the cylinder they were not supercharged until they used a turbo. Also not much low end torque as compared to a 4 stroke, hard on fuel too.

 

I ran an old 12v71 in a truck that was set up way way hot. Flat land running it would do the roll but if it saw a hill it turned coward of the county. You could get passed by a wore out VW microbus on a very slight grade. But with twin straights and a 13sp you had a ride that sounded like it would pull heaven to the cross and had a sound that would wake the dead. Between this truck and a few 671s and 8v71s with straights is probably why I have to have the volume on the TV LOUD. LOL the best thing about the good ole days is they are gone.

 

I think you're being a bit generous on the horsepower.

And you're being a LOT generous on horsepower. The key to horse power designations in the Detroits is their series numbers; 6V92= 6 HP, 92 leaks. 8V92= 8 HP & 92 leaks, and so on and so on.

Especially when it stops! For the life of me I cannot understand why anyone who was familiar with these engines would willingly buy one, knowing that they were going to have to listen to it scream 8 to 10 hours a day, not to mention that your hands felt like you had held onto a hammer-drill all day when you were done driving.

Boat anchors.

chaikwa.

 

LOL. Having not driven one at a point early in my life I thought some of those guys had stereo headphones on since they were driving pretty nice rigs. Until I worked for an outfit that ran 8V71's. I was at Sanderson Safety the very next morning for a pair of muffs. Summer time and a tanker with twin short stacks was NOT a good thing with no AC. They sounded and ran like a hot rod on the flats but fell on their face on a hill. Would get passed by triples on Cabbage hill.

 

My first 10 wheeler was a 61 GMC with a 401v6 gas motor ....you want to talk slow then I stepped in to the BIG league with my first 8v71. then I learned there was real big power to be had...hence silver8V92TA. But my BIG CAM 400 would walk all over them

 

V6 GMC with huge cubic inches and nooooooo fuel mileage. But they didn't do a bad job. The younger generation will probably never know what a screamin jimmy 6 or double breasted yamaha 8v71 was really about. A/C on a "few" trucks when it worked, most had 2/60 a/c "2windows open at 60 mph". The good ole days-sure glad they are gone.
