Don't be such a smart EDIT! You have to at least give him 15! haha

 

Agreed. I want to keep this board clean also. If anybody has doubts they can travel to the chev boards, check out the war area, and see the dribble that he posts. He is very anti Cummins, so the only reason he would be here is to stir trouble. I am done with him.

 

Not here to stir trouble. Excellent then, civil discussions with fact and no preclusions of fiction. Never ever anti Cummins , I still own some.

 

OH really? The Duramax has 650 ft lb torque at 1600 rpm (The Cummins has 615 at 1600 rpm) So please explain to me how the 615 is more then 650 at the same rpm!
The Duramax get at least 50% better fuel mileage then the big block 8.1L gasser. (Or the biggest gasser by Dodge and Ford)

 

To get this post back on topic.

I am actually pretty impressed with the performance that the duramax has shown since its release. Sure it has had its problem (still has some problems) but what new engine doesn't have issues? Even the dodges have issues even if people dont like to talk a whole lot about them.

When the engine first came out i expected it to be much like the 6.0L ford but i would much rather own the durama over the 6.0 ford any day.

I think the simple fact of the matter is the cummins is a more reliable engine for one of the main facts that we are compairing a straight 6 design against V-8 designs. The straight design will always have less internal wear then the V design regardless of diesel or gasoline.

On the electrical aspects I'm not even going to get into because i dont even want to pretend like I know what i'm talking about but I stay with my theory. The less electronics the better.

 

I think you're right on the mark. Let's talk about some Cummins issues, for example. How about cracked heads and dowl pins on the 12v. VP44s, lift pumps, crankcase ventilation (puke bottle), and 53 blocks, on the 24v. Head gaskets on the 24v HO. CP3s, lift pumps, injectors, and dropped exhaust valve seats, on the common rail motors. Every generation has had problems with cracked exhaust manifolds. There's probably some more I've left out. There's alot of ammo there for the Dmax guys to shoot at Cummins.

 

Most of the problems the Cummins has rear their head after the engine has a considerable amount of miles on it:

Dowel pin 100k+
VP44 80-100k
Manifold 80k+
53 block 120k+
24HO gasket not really an issue worth mentioning.
Puke bottle being filled with oil is not an issue. Thats what it is supposed to do

The "other" engines like 6.0's were lucky to make it off of the lot and down the road.
If you call ammo against Cummins something that happens 100k into its lifespan SO BE IT.

Gimme a break....

I'll take my 120lb crankshaft and 150lbs head, and 300lb engine block any day of the weak over the "competitors" garb.

 

Guys, keep the personal attacks off this site.

I traded my 05dmax for an 06 cummins and am pretty dissapointed performance wise. Both truck are 6speed extended cab duallys. I figured the cummins would do better but it pulls the same and gets 3 less miles per gallon. Duramaxes are pretty reliable from what i have seen.

 

well considering 03 and 04 were the first years of the 6.0L Powerstroke, you think you would understand having problems. no one gets anything right the first time. and with the 05 Powerstroke there had already about 20,000 changes made to the engine. and my brother has a F350 6.0 and has 22000 on it and gets 14-15 road/highway. doesnt pull all the time but when it hauled my truck 88 chevy crew cab dually that grossed about 8500 plus the trailer it got bout 14 with a superchip tuner turned to max. the same day he pulled a sled, hauled my truck, and still got 13. oh and he won the pull stomping all cummins and duramax's. next truck to him was 25 foot short and he only hada programmer. there was a dmax that had nitrous, propain/methonal injection that came in second. so as with any new version of anything it will suck and have throw backs.but it seems that no one wnats to admit that there is junk no matter what you buy. hell i love the cummins and hate chevy's but i own a chevy with a cummins. i would much rather have a fordcummins or a stroker but not for the price. so alteast admit that there are exceptions to the rules. and unless you can prove otherwise dont go raggin on people cuz yea info could be wrong but who are you to say it aint true unless youve seen it.

 

Thought the subject was about durability to 300, 000 miles and over, not problems at a "considerable" 100,000 or so.

I'll take the Cummins over the other brands any day of the week, also. But your response is no different than the 6.0 fanatics who think it's the best thing since sliced bread. Face it, the Cummins has it's share of problems and blind loyalty doesn't hide that fact. It just happens to enjoy a good reputation.

By the way, the puke bottle WAS a pretty stupid idea. How many dealers service it at oil change, let alone individual owners, Jiffy Lubes, Walmarts, etc? Don't service it regularly, and within 2 or 3 years you've got a plugged radiator and overheating problems.

 

You know what guys they're all made of the same stuff there are good and bad of everything, and with the market today, there is a performance part for everything!

 

Bart and Broker, you guys follow each other. It's pretty funny really.

 

Okay, since the chevy guys want to throw numbers out then try this. The following are from Banks, you know, they made the cummins the fastest truck on the planet and they have the duramax they have built. The flywheel numbers dont show what gets to the ground. They can be fluffed from the manufacturer due to drive line losses. This is banks' numbers for stock, go check them out:

Torque Horsepower 0-60
Chevy 445 max 229 max 10.18 seconds

Cummins 493 max 223 max 9.76 seconds

Now, as far as the 0 - 60 number, who cares in my book, that doesnt tell which pulls longer, better or has reliability.

As far as torque and horses, the dodge is closer to the flywheel ratings than the chevy. A lot closer. Also, more torque to the ground out of the cummins. Finally, I check the torque and horsepower curves for stock, to the ground of course.

Torque
Chevy 450 at 1800 to 430 at 3000 (usable power band)

Cummins 500 at 1800 to 460 at 2800 (usable power band)

Horsepower
Chevy 150 at 1800 to 240 at 3000
Cummins 170 at 1800 to 240 at 2800

OBVIOUSLY, the CUMMINS has more low end pulling power. The torque and horsepower to move the load at a lower rpm. Can maintain the lower RPM to achieve better mileage. That said, where the chevy has the current upper hand is the tranny. This is why you see them drive so well, take off so well. The six speed and the allison design allow them to stay in the peak power band, for pulling or for daily driving. They can shift in and out of gears to keep the prime power. However, this is to change, like all things. The dodge is going to have a comparable tranny thru Aisen. This will make the same rated cummins motor seem much more powerful. I believe this is what happens with the duramax. Not to say its not good, but the Allison makes it better than what it would be with say a 48RE tranny. That said, I have 150,000 miles, no problems, i have spent about 1000 in repairs for odd ball things. Not bad in my book. My brother in law has a gas motor chevy, spent over twice as much with less than 100k.
