I don't hang my hat on what the rag's say either, but when EVERY test has the same results, no matter the configuration of either truck (the Ford beats it badly), then that body of evidence becomes a real factor.

 

See, again that is all in opinion. Seriously if it does beat it, it is not BADLY beating it. If it were that much better than the Cummins than everybody with a Cummins would be buying a PSD. This is not like this is a Ferrari versus a Pinto. We are talking about a difference between the two that is not very much at all. So little of a difference that simply because the Cummins has a reliability factor that is very high that someone would purchase the Cummins over the PSD even though it may so-call beat it BADLY!!!!! Look a diesel engine was not designed for speed. It was designed to haul much larger loads than a gasoline engine. The fact of the matter is faster or slower the Cummins will get you where the PSD can get you, but it will get you there many more times than the PSD because of the TRIED AND TRUE reliability of the Cummins name and engine!!!!!!! Who is in a rush!!!!!! So it takes you 5 minutes longer to get somewhere with the Cummins. At least when I get there my Cummins will still be running!!!!!!

 

Everyone who buys a PSD is in a hurry thats why they buy 'em, Nobody needs to tow at 85Mph, you are just a menace to everyone else on the road when you tow 10K pounds at 85Mph. Just like the guys with a snowmobile deck and 2 sleds with gas and all the other stuff loaded onto a 1/2 ton, not as much weight but just as dangerous. A 1 ton trucks do not have the brakes to be stopping a load like that from 85 or faster.

 

Finally somebody with common sense. Good reply 351M. Reliability will overcome any other advantage another diesel engine may have!!!! Who needs to speed in a truck anyway?

 

Of course the PSD spanks the Cummins in acceleration, its a V-8 vs. I-6 for god's sake the pride of Ford would diminish if they let an I-6 win. And the "alleged" low end torque isn't alleged. Everyone knows that even Ironman admits it. and where do you get this Cummins fares worse than the PSD the larger the load? I looked for a few tests but haven't found anything much so far. Check out this picture though- http://www.swiftindavis.com/sblog/?itemid=143

 

Heretic, Chomsky and 351 are all in need of some serious therapy treatment. Shhhhh. Don't continue to reply with all the previous charts, graphs, calculations, and engineering analysis. They may go postal on our thread.

Chomsky thinks the Cummins with a manual 6 outperforms the PSD/TS, despite the objective tests and photographs. Heretic thinks 2-million mile volvos and Chevy 250's are stunning proof of the superiority of the Cummins technology over the PSD technology. 351 is worried about all the Ford/PSD's driving at 85 mph (actually a good point. My cummins is almost red-lining and shaking at 85, but in my PSD I can't tell the difference between 55 and 85).

DieselDoner ... reminding them that the PSD spanks the Cummins in the tow-tests will only incite riots here.

Listen ... these guys are protecting the Ali-Dodge-Imam mosque and will argue us to the death. Reason and logic have no place here. These guys scream "lalalalalalala" as they rush in with their suicidal cummins love notes. They appeal to the great Volvo inline engine-god of inline engines.

As Reagan once said, you can't negotiate with Dodge-terrorists.

The Ironman

 

Just to point out the new 600 Cummins is not the same as the 12 valve or the 03 24 valve so why are you basing the reliability of a motor that is different than the new one ?

 

And??? So it weighs a lot but it doesn't posess hardly any rolling resistance. We move down equipment with Chevy 1500's. It's not a challenge. That pic is laughable if you think it proves anything. Let the air out of the tires and see if the all mighty Cummins will move it. Show me something....

 

Obviously Marine Ironman is in the need of help. Not only are you completely blowing everything way out of proportion, but you can't even come up with a good nickname for me. Once again you are solely basing all of your arguement on tests that you were never around in the first place. You also said that your Cummins is almost red-lining and shaking at 85. Anyone who has a half of a brain knows that this is complete crap. Your problem is that you forgot to shift the truck from fourth to fifth (Assuming you weren't stupid enough to buy the Dodge automatic) I completely agree that the PSD is faster if you are trying to drag race. All I said was that when it comes to reliability, the Cummins has proven itself for a much longer time than the PSD. That is Ford's fault for being a company that cant provide their customers with a truck with a worthwhile diesel engine until the Powerstroke. Now that it has all you PSD guys are gung-ho about it. As far as the 600 being new. The fact is that almost everything is the same. Cummins has had the 5.9 since it has been in the Dodge. Ford had to change their whole motor to compete w/ Dodge. MMMMMM What does that say about reliability that the Cummins has by being able to basically use the same block for a long time. I don't give a **** what the magazines say or any test. I know what I know from driving both, and my opinion is the Cummins is the better engine. Why does Marine Ironman own a Cummins if they are so badly beaten by the PSD. That Cummins that supposedly shakes and red-lines at 85mph will still outlast whatever PSD you might have.

I never actually said tow-tests I said acceleration meaning 0-60

I just thought the picture looks cool I didn't say look at this a PSD could never do it. As for letting the air out of the tires how often to you tow something by dragging it on a trailer with no tires or better yet lets just start dragging crap on the ground to prove a point.

 

Plenty...you should be around when dead track equipment needs moved (dozers, excavators) .

If you haven't checked your radar lately Cummins is no longer the rival of the PSD. Chevy is running a high tech Isuzu V8 design also. Which is more up to par with what the Power Stroke is doing. Navistar did not build the 6.0 to compete with anyone. It was engineered for lower emissions, better economy, and to better utilize the technology available. With all that said it would be easier to start from scratch that to revamp the 7.3.

 

Chevy may be the more publicized rival now or a better rival in sales I have no idea. but no real diesel owner on this site really considers the Duramax a worthy competitor for the Powerstroke. All of the debates involve the Cummins and Powerstroke. I hardly see any D-max mention unless you include the unsubtle turd and pistonslap comments.

 

Hp involves a few things. Force distance and time. 30000 lbs 1 ft in one minute. So if an engine makes 555lb ft of torque at 1500 rpm and another makes 500 at 1500 rpm. The torque is the force. The rpm is the time, per minute, and distance. This is figured by the rotations. Imagine holding a stick in your hand and spinning around in a circle. Then you measure the diameter of the circle. Thats how they derive distance from a spinning crankshaft. Its a 2 ft diameter circle with an imaginary 1 ft bar.

So we take 555 x 1500 then divide it by the distance 5252 and we get 158hp at 1500 rpm. It makes slightly more but whos counting. So then we take 500 x 1500 / 5252 and we get 142.

The cummins makes slightly more than 158hp at 1500 the PSD makes 142hp at 1500. There is no allegedly. It is a fact. More torque equals more hp. At the same rpm.

The cummins torque curve allows it to make more hp than the 6.0 at all rpms below 2900.
