Well, you of all people should know that this whole thread is pointless. I have a lot more respect now for you knowing that you took the time to look that up. You must really love your truck. As do I. And I know that I could *probably* hook up to any PSD on this thread and prove myself, but I also have a lot of money invested in my truck to ensure that. For the record, I have had 2 power stroke's (1 van, 1 Centurion Dually) and one N/A 7.3 and they are good motors. But I am of the opinion that the 5.9 Cummins is a superior motor for this application.

 

wise words

 

That's the thing these guys talk like the cummins has never hed a problem and that they are the only one's that use thier trucks for work. It's so funny you give them examples but hey everyone is lieing if they say the cummins didn't perform well against the others.blah blah blah.

 

Just as an aside, the 6.0 won't rev up to 4k. The most mine is good for, even shifting the auto manually, is 3600-3700. I still don't understand the redline on the tach on these things. Who are they kidding? It really doesn't rev out much more than my dmax did when just flooring it and letting the auto do it's thing.

 

Actually my Cummins has never given me a problem... but as i meantioned before, the clutch and the pinion shaft have. No truck is without it's problems, especially when you hot-rod them

 

someone looking for a ford with alot of miles as i posted i have a 89 with 220k and it has never been on a tow truck, general maint, and a water pump , also a 03 with not one problem yet 8k,still new but great, 16.7 empty,13.7 pulling 36 ft fifth wheel 16000 lbs before we load it, poss 17-18 full of junk, pulls the house down point blank fact ,both in use today

 

I have to be partial to the Powerstroke due to the fact that I own one, but it never ceases to amaze me that people can not or will not look at the engine specifications on the Powerstroke and Cummins and be able to come to this conclusion:

Both are exceptional diesels that have proved themselves over and again. Both are very powerful. Both have thier problems and both will last forever if taken care of.

Now as a day to day driver of either the power of one vs the other is negligable, I don't think anyone could tell a difference, but we work our trucks so this is where the difference comes to play..... If you consider stock vehicles one with the Cummins and one with the Powerstroke, you really only have to ask yourself one question as to which one you would prefer, Brand loyalty aside and that is am I going to put this truck on the farm or am I going to haul down the highway. The Cummins is the superior engine for the farm application, lower end torque which equates to a lot of power at lower speeds, not to insinuate that it is not capaple of highway use, rather that it is more suited for applications where speeds are lower. On the other hand the Powerstroke does not have the advantage of the torque being so low on the RPM scale, which equates to sluggish slow speed pulling performance. It does however reach peak torque at 2000- RPM's for those of you who dont know is rouqhly 70 mph in overdrive, so Its plain to see where it would have an advantage on the highway or longhaul application. To be completely honest, I would be driving a Dodge with the Cummins if I were using it on the farm, but I haul distance and chose the PSD. There is absolutely nothing wrong with the Cummins, its a great motor. Both will do nearly anything you want them to, but put brand loyalty aside and think about what you are talking about before you post.

One last thing, the Cummins in my experience does seem to get better fuel economy and thats nice for a grocery getter, but If your truck is put to work for the purpose of making money, I think the 2-3 mpg difference is probably negligable in the long run. Besides in the spirit of the tax season, don't you know fuel is deductable

 

While that's true of the 7.3PSD, it is not true for the 6.0. At least not yet.

 

Jeb

not to argue with you, but i was speaking of the 6.0. It reaches 560 ft/lb @ 2000 rpm.

the 7.3 which I own reaches 525 ft/lb @ 1600

in both applications there is not a substantial torque loss up and until around 2700 rpms which on the highway would probabaly be around 95 mph or so. I don't know about anyone else but i won't haul anything that fast...

 

Well said bigdieseldav.

Ok...I happen to believe that the Inline Cummings is a better engine only because of the "Inline" factor. It is my understanding that it will last longer than a diesel V8. Since it takes less to balance an Inline 6 as it does to balance a V8. This is really critical with the amount of torque produced...and the compression ratio's. Wish Ford used the Inline design...

Now...with all that said. Ford did an outstanding job getting the 6.0L to where it is. All the power/torque and anti-knock features make it a truly "modern" engine. Again, just wish they would have used the Inline design.

Just my .01+ .01=$.02

Oh...if I am totally wrong about my observation...please tell me why? (nicely)

 

Ford did an outstanding job on the 6.0????? I don't think so.

 

Here's my opinion:

The Cummins I-6 setup is ideal for set-throttle applications such as pumps, tractors, and heavy machinery (even though I prefer Cat). The Power Stroke is better suited to road use.

To those who said the Cat 3208 was no good in the MF tractors...here's a possible explanation. I think that since a tractor is a set throttle application, the constant engine speed wears an engine out faster than acceleration/deceleration applications. The Inline set-up is better suited for a tractor.

Look at the power boats and charter boats and other types of boats, a bunch of them run V-8 diesels.

If the I-6 is the best balanced type of motor, then why is an I-4 the worst?

 

Hey guys I'm new to these forums, but I have been around diesels all of my life, growing up on farms, operating heavy equipment, driving big rigs and also owned all big threes diesels. Some of you make good points and some I wonder where you think up these ideas. LOLOLOL Anyways, I don't own a Duramax, but my brother does. No problems and he really likes it, he has a PSD 7.3 also he really likes both motors. I have PSD 7.3 and Cummins 5.9 1997 version and a GM 6.5 liter. The 6.5 liter is not that great, but it has 140,000 miles and still runs real well with a service bed on it and weighted down. What I'm trying to say is that you really can't go wrong with any of the big three's diesel motors. Since they are required to give 5year/100,000 mile warranty on diesels by law, they don' want a white elephant out there on the market. Each motor has different little advantages and disadvantages. You just have to pick which advangtages you like.
These comparisons with cat and other models are pretty much worthless in the pickups. Yet in equipment and big rigs its about the same kind of deal. You have mainly Cat, Cummins, and Detroit Diesel. I would take any of these in the right power configuration. All good motors, but once again little advantages and disadvantages in each one.
Right now I'm in the market for some new service body trucks with diesel configuration. I'm buying Ford. Why? It's not because I think it's the best diesel by far. It's because I think they have the best crewcab of the three trucks. Don't flame it. If I was to say I was picking by motor, I would be buying dodge. For these two reasons: better fuel economy since we put lots of miles each year, and I personally like I-6 motors. But like I said earlier they all have good and bad points.
As far as the HP and torque arguements, pretty much everyone with a diesel I know has done modifications with chips, programmers, exhaust, air filters, etc. So depending on what they know or how good the person selling them this stuff was, their HP and torque are all over the place. So stock HP and torque really don't mean squat anymore.
Thanks for reading. I just get frustrated reading some of these posts and wondering how much real life experience that some may have.

 

Sorry, I should've edited more out of the quote above. I was talking to when you said it's proven itself over and over. The 6.0 has a long ways to go before it's a proven motor. It's not even in the ballpark at this point, IMO.

 

I know what you mean, and i did kinda mince words. the 6.0 hasn't proven itself yet but i kinda meant the Powerstroke line of engines are proven.
