Chevy guys sure wouldnt agree with you. My friend with a powerstroke seems like hes always faced with a challenge from a duramax somewhere or another. My friend doesnt showoff or answer the challenge though. But no matter how you look at it. The powerstroke will dominate the duramax.

2 inlines with a million.

mobil 1 event took an inline 6 a million miles.

Another one but only an inline 4.


Im still looking for these million mile v8s that you mentioned.

 

Debating is puryfying to me. I dont really care one way or the other. I just love the debate. I would take any of these trucks and be happy. A dmax, psd or a cummins.

 

heretic,
I don't need a lesson in how to figure hp. I'm saying "allegedly" because we all know of examples where manufacturers have claimed one thing but what they produced was another (remember OJ only "allegedly" killed Nicole). If the Cummins outpowered the PSD down low to any significant degree it would be seen somewhere in at least one of the numerous tests that have been done. unfortunately for you and the rest of the Cummins-lovers, it just doesn't stack up in real world tests. To paraphase and adapt a quote from a recent movie "It has been weighed, it has been measured, and it has been found wanting. In what world could it beat the PSD?"

 

I seen people pull trains with there teeth. I don't think they could do that very long without some major problems. If you want to pulla train get another train!!!

 

Actually bigsnag. If you read the tests closely. The cummins takes an early lead. Then the psd outruns it in the long run. Even the 305hp cummins would jump the 325hp PSD. In the long run. The road belongs to the PSD. So it is apparent in the real world tests. I have provided the quotes and the links in the other thread which shows the cummins with the early lead. The PSD has a gearing advantage so it easily ropes the cummins in and outruns it. Down low though. Belongs to the cummins. To really understand this you have to look at it with the 6 speeds. The autos dont really show you how an engine performs down low.

 

Look at the contact patch on a train. Not a fair comparison. That big loader in diesel donors picture would provide much more resistance than a train. A train axle weighs over a ton. But you can push ione along the track with your pinky. No kidding.

 

Yes, I am ROTFLMAO too. A lawnmower engine with a good set of gearing could move that dumper. What you will NOT see is Dodge sponsoring a tow-off against a PSD. Why? Because, as in all the tow-offs, a Dodge Cummins will lose to a 6.0L PSD.

Just to throw a monkey wrench into the arguments, another aspect of the drivability of any vehicle is how it responds at less that full throttle. The PSD was redesigned to provide improved fuel economy and reduced emissions during standard driving/testing. It is better set up for every day use, which is one of the reasons it is more enjoyable to tow with. That's why the magazines like it. Yeah, the acceleration numbers are great, but if you're looking to drag race, don't buy a 3 1/2 ton truck.

 

Hey ... so you ARE familiar with the Dodge problem. Yep, I have the Towing-Special Dodge. Of COURSE it has an auto transmission, and it has a 4.10 rear-end. Why? Because that's the best towing configuration, even Dodge knows that, and sells them under that labeling. I don't think it's capable of going over 85. He he. I've had great times w/ my truck. But her days are over. She sits most of the time now, while I'm out in my PSD.

Well whattya know. Old Ironman knows what he was talking about. Shake, rattle and roll, baby. Your teeth'll come out.

Yes and how much air was added to the tires on that Dumper? Real worls say's it would blow it's tranny in a week doing that stuff! Oh yea I bet it voids the warranty too. I'll stop by a Dodge dealer and ask him if I buy one to pull those things around if they cover it when it blows!

 

Hey DD7.3 .... there's a Chebbie Guy on this forum called DMAX-HD who goes around touting Chevy 2500's on this website. He's actually done something smart, and bought a Duramax ... which IS a decent engine. My only point to him is ... as long as you're going to go for one of the top two (PSD and Duramax) ... why buy Jap? Buy American, and you still get the edge on the performance, too.

I think the majority of it is how much you pull and how you pull it and the terrain of where you live. My example, i live in a place with for the most part straight roads but there are a alot of sharp curves in alot of places. I pull 4-5 days a week a 7 horse slant trailer fully loaded (comes to be around 12500-13500 lbs depending on which horses i am hauling from day to day) 130 miles one way during the summer and most of the fall. There is no interstate so i have all secondary roads. Considering the dollar value of my horses there is no way in hell i would think about going much over 65 on any of them. Now with the curves taken in effect i have to slow down significantly on a few of them so i like the better low end grunt and the close geared 6 speed of the Cummins/Dodge. I also took note that the dodge was cheaper and had a better sound system (nothing like CCR on the open road!!). I am not picky about overall comfort, compared to what i used to drive almost any vehicle these days is more comfortable and tend to keep getting better. If i had more money to spend on a vehicle, trusted an automatic, and hauled an enclosed trailer of any property other than livestock i would get a ford w/ the PSD. But i dont tow anything at 80 MPH so i dont need to spend the extra money on a Ford. At the rate i am at I can trade in every two years so the pickup itself wont shell out and in that i cant really justify spending more on a Ford or a Chevy. Dont get me wrong, I love alot of Ford products and will til i die (the 7.3, the 4.9, the 6.8 V10, interior styling etc.) but as of right now i see the Cummins as best for my current situation. Real life facts from a real life guy, I dont see how anybody no matter what brand they are behind can argue with how i just explained Cummins VS. PSD.

 

Heretic: you can save us the 5th grade math. We laid all this out in the "PSD is the most durable engine" thread. The PSD not only has way more area under the total curve (which is what counts), but I did the math for each engine in it's power band, with a 3.73 rear end, and their transmission gear ratios. Guess what. The FORD is putting out MORE RPMS to the rear wheels in all gears. Hmmmm. Could that be why the Ford wins all these tests? Go back and look in that thread, and you can check you math and answers against my tables.

Heretic, here ... drink your own medicine, and I quote:

"The HEMI engine with MDS has completed over 6.5 million customer-equivalent miles through Chrysler Group’s development and durability testing"

How's that for a twist? I give you a Dodge V8 as the first example. Let your fingers do the googling for the rest. You'll get hundreds of hits.
