Who has a Duramax pickup?

I had an 02', 2wd ext. cap, shortbed.
I liked the look of it better than the newer ones.
I got about 19.5mpg avg. (70/30 hwy/city), and I drove it hard and fast...avg. is probably 70 to 75mph.
It was a great truck, very smooth on the road.
I didn't like the small tank, or the small filler hole. You can't fit those bigger nozzles in there. Plus filling up sucked if it was shooting in so fast, b/c it doesn't vent quick enough. Those small annoying things was the only thing I didn't like about it.
So, you really can't go wrong.
 
Hmm, So I'll be the black sheep in this thread.

If I were shopping for an '04 diesel tow rig, It would be the Dodge with the "redesigned" Cummins 600. I can't remember where I saw this, but it was a picture of the connecting rods of the big three diesels. Power Stroke, Duramax and Cummins. The Cummins rod was massive compared to the others. That said, I have driven both the Duramax and Powerstroke trucks. My bud just got a new to him PSD F-350 Ext. cab dually. Chiped, straight pipes and all. That thing is sooooo impressive to ride in and tow with. A good friend of my gramps has the '03 Duramax 3500, chipped with all goodies, and its pretty damn impressive as well. The Cummins is the same for the most part, but after seeing the picture of the connecting rods, I'm convinced. I know Lance over at PBB just got twin turbo's for is Cummins, he's expecting something like 800lb-ft of torque and 500hp... /forums/images/graemlins/bow.gif
 
exactly why I'm gonna push dad to get a GMC. Don't look as good as say your HD to me but a lot better than the Chevy look. I think it will be his first GMC but whatever. He did specifically say when I asked him what trucks he was thinking about that he was mainly thinking GM Diesel, so I think hes already leaning towards a GMC.

Isn't that just because it's an inline 6?
 
twins and 500 hp is a tow setup. The redesigned Cummins I don't think is that special, just a tuned up standard one. Personally I'd go with a Cummins equipped mid 90s rig myself. But i'd also go stick and dually. I'd prefer to see my dad back in a GM vehicle. Hes always driven GM vehicles till the F250 and it treated him like crap so yeah. I have heard the quality on the newer Dodges is a little poor and they go through Balljoints. I should ask Chris D he has a 2500 Hemi rig. My mom likes the look of the Dodges though, and we all know when the female of the relationship likes it, it is a lot easier to work out.
 
Exactly. Of course the 6BT is bigger, it's an I6. And the other rods are old 6.2 and PS IDI. Not current at all.

Not saying the Cummins is not a good motor, I just don't care for the wrapping. Now if they still made the previous body style with a real crew cab, I would probably be driving a Cummins, but I do love my DMax.
 
That could be...You decide. I did a bit of searching and found the picture on PBB-

So each PSD rod has to take care of .75 liters

Each CTD rod has to take care of .983 liters

No 6.2 rod in the pic...Duramax and PSD 6.0. /forums/images/graemlins/thinking.gif
 
And for the record, I've been somewhat seriously lookin at getting a used '98-99 24 valve CTD Dually. I don't really like the way the new ones look either.
 
is it just me or are those 3 different pictures pasted together into one? Could be said that its all an illusion of the eyes. I'd be happier seeing a picture on a workbench of all 3 side by side, to get an unbiased view.
 
Hmmm, sorry, different pic. The one I saw floating around a month or so ago was pegged by a Diesel tech on TDPlace as being mislabeled, which is what I was quoting. Those look different than I remember, and they are not oriented the same as the other pic, so that may be accurate. /forums/images/graemlins/blush.gif

I still am not swayed in my views on how the engines relate to each other. The Cummins wins on durability and brute strength as well as weight and size. But for my use, it’s not worth taking the wrapper. Now if my DMax takes a puke outside warranty… I may have to see what it will take to squeeze the Cummins 6BT in there…
 
Now that you mention it, yeah, it does look like a chop...

Hmm...let's think about this a bit. First, the ctd rods are taking roughly 33% more loading simple due to the fact that there are 2 fewer of them. The relitive displace ment is irrelivant, sicne the loading on the rods is a function of the torque the engine is developing, and both the psd and ctd are roughly the same in this regard. Also, the cummins has a longer stroke, and thus a longer rod. Now, it's pretty obvious that having a longer rod will make it tend to bend more than a shorter one. (to demostrate this, try standing on the center of a 8' 2x4 help up at each and and then one supported 2" on each side of where you're standing) So, it has to be larger to withstand this force. Also, a longer stroke means more of a horizontal displacement, which also transaltes to increased flexing requiring a stronger rod.

And it's should be pretty simple to figure out that the engineers that designed the engine knew far more about this subject than us. If not on the solely theretical side, (I'm sure there's a few automotive engineers on here) directly related to the engine. They would have all the data of strengths, speeds, forces, etc, that we can only guess at. And then, you have no idea what material that is, either. With the variety of modern alloys and proccess, it's very possible that the psd is smaller due to a stronger material, and not a lack of strength.

And then, there's the really important question. How many of these engines, either psd, duramax or ctd have failures resulting from the strength of the rods? I seriously doubt there's very many, with the expetion of those trying to double or triple the stoick output. If you do that, yes, things will break. But for most of us, it's irrelivent.

Okay, now that's only about the 3rd time I've wrote this. Mabey I should save a copy for the next newbie that posts this.

I agree, cummins is an excellent motor, I'd love to install one in an old Chevy /forums/images/graemlins/grin.gif just can't see a Dodge in my future.
 
much better example picture /forums/images/graemlins/wink.gif /forums/images/graemlins/waytogo.gif though the rods look little next to the cummins one they still look bigger and better than they do in that other picture you posted.
 
Actually, I believe that's the pic I was thinking of. I don't remember the details, but it was stated that the 2 on the left are old tech. Also, like the other post said, size isn't everything, or so I'm told, and not everyone NEEDS one that big to get the job done... /forums/images/graemlins/whistling.gif
 
It's not the size of the boat that matters, it's the motion of the ocean
 
I agree about the motor being decent , but the wrapper on the Dodge just doesn't work. I can't believe after all the engineering that goes into a new truck, that Dodge would give such a small back seat in the crew cab. It's insane to me. No way I could fit any customers back there. Dodge would have stood a chance with my decision if they'd have made it a real crew cab. /forums/images/graemlins/angryfire.gif

Cool, first apology I've seen on a post. /forums/images/graemlins/waytogo.gif /forums/images/graemlins/waytogo.gif /forums/images/graemlins/waytogo.gif
 
I know looks is all personal preference, but I think the Dodge has the best look of all 3 right now. I like the look of the new dodge. And as for rear seating, although not as much room as a real crewcab chev & ford, I have never had anyone complain about lack of room in the back, even one of my best buds who is 6' 4". Although I don't hang out with any 300+ lbs dudes (or chics for that matter) /forums/images/graemlins/ignore.gif

This looks good to me /forums/images/graemlins/thumb.gif:

Here is my old chev, which I like the look too (except for the taxi cab clearance lights /forums/images/graemlins/whistling.gif

But I have had more compliments on this dodge than I ever did with Chevy...not sure why, good looks? /forums/images/graemlins/dunno.gif
