Is a dually needed?

Who makes the best sounding diesel? . . .

Caterpillar

actually I'm a little partial to an 8 or 12 cylinder 71 or 92 series Detroit at full bellow

My dad has a 8V92 and 6V71 Detroit powering his sawmill. That 6V71 is probably the best sounding engine I have ever heard!

Daugen and Kevin,

I'll just say to each his own. I've never cared for the sound of a "Driptroit Screaming Jimmy."

If you are used to the sound of a gas engine, a high performance gas engine even more so, a diesel will take a little getting used to. The truth is, I like the sound of just about any engine running. I love the sound of a Cummins in a Dodge truck with a low restriction exhaust installed. They have quieted them down quite a bit since the original 12 valves.

yeah, I learned to buy diapers, oil ones that is..., by the case of 100. And lots of Delo 40wt.
But with two turbos, my pair of 8V71TI's didn't scream, and their pipes played sweet stereo,
though the guy next to me had 8V53s I think, an older engine, and boy did they bark.
But then I had mufflers six feet long in my boat; his sounded like straight pipes.

sometimes I think the big rigs are musicians playing an instrument. Baaaarrrooooooommm, one more time
The challenge is what you hear outside is likely very different than the engine noise inside. I bet someone has recorded a video, or ten...

let's see, thinking of the really important stuff now...I need to get two bumper stickers.
My other diesel gets 45mpg
for the truck...
My other diesel has 800# torque
for the VW...

Is the Allison the strongest of the big three transmissions, so therefore it could handle the most boost/torque?
that's another issue. That one trans has such a good rep it does sway me a bit to the DMax. Now I would be pulling well within the
capacity of both truck and trailer, but what if a little boost is added? Just curious. Seems like a lot of chipped/boosted engines out there and no one
seems to be complaining of failure.

I think of the Cat 3208 that started at 210hp and went over time all the way up to 450hp. The DD engine like mine did the same thing. First came the turbos, then the intercoolers, then bigger injectors, all the normal stuff, then electronic ignition tied into thermocouples so that higher boost would hopefully not toast your engine. Of course the new ones are so complicated that few of us non techies can work on them. Other than change the oil and easy stuff.

The fact of the matter is that with the hp race, most of the oem engines are pretty boosted as is. I mean, do I really need more than 750-800 foot pounds?
When you guys tow, do you always wish you had a little more oomph, and not the fantasy stuff...but like slowing down too much on long hills with heavy but reasonable loads? where it wouldn't hold the gear you wanted? And I'm not talking Pikes Peak either.

lot of questions, sorry for jumping around.

If you get into a 1 ton Dodge, dually or single rear wheel, you can get the Aisin transmission in a Dodge. Its been available for a few years in the chassis cab trucks. Its suppose to have a really good reputation also.

Power for towing? Its kind of like having too much money, its possible but not usually. I'd say just about any modern 1 ton diesel truck will have all the power you need.

Exactly the Aisin is a great transmission. It is worth the upgrade in price if you are going to be tuning the truck. From what I've heard from a lot of diesel guys is the Allison is great if you leave the truck stock. If you add much power the Allison will grenade. Same with the 68rfd I think is the base auto in the ram. The factory 800 lbs of torque is all they want. Plus is you get the Aisin you get the 850 lbs of torque from the factory and the ability to handle tuning more power. I have the g56 manual in my 2012 and when I run on my highest tune I could over power the clutch. I removed the stock clutch at 30,000 miles (it sill looks brand new) and put a southbend clutch kit in. Now I can get all the power to the ground with the highest tune. 120 additional HP btw.

what do the bigger trucks use? Back to the bigger Allison versions?
I'm learning about them studying motorhome powertrains, and the "small" Allison
seems to be the 1000, and the models increase in size as the hp goes up.

that's what we need in our trucks, a nice diesel pusher engine...:dance1:
and I'm quite sure no one, but no one...would complain with 1400 pounds of torque.
Of course the trans would explode the first time you hit max boost and then all those lovely
little red lights light up on your dash. Check remains of powertrain.


I'm quite happy with a modern six or more speed auto transmission. 4.10 gears with a
deep overdrive for unloaded highway use sounds good to me. but maybe a 3.73 is all I'd need with
this. Whatever comes stock is most likely what I'll find used.
