05 cummins - 610 lb-ft torque

[Tomeygun]

just so everyone knows,



The new 05 cummins make 610 lb-ft torque at 1600rpms



I just got the e-mail about it, said :this is to maintain its leadership spot as the strongest heavy-duty pickup"



FWIW

 

[lschultz]

Thats great.

 

[Tomeygun]

back again,



I did some searching as to why, and found it was not the NEW 05 ford, but the 605 torque of the duramax that made Dodge step it up... .



Ist amazing that ford and chevy both claim the most powerful diesel, yet we beat them both!!!

Tommy, have you seen an '05 with a moon roof yet?

That's ALL??? :-laf



Just kidding - I drove the truck out to our dealer to take my wife who was picking up her Durango from its 36K service. A salesman immediately ran out to meet me - "When are you gonna trade your old truck for one of the 3rd generations? It has much more power!" I answered, "No, it doesn't. " He looked puzzled and said, "Yes, sir, it does. " Again, I said, "No, it doesn't have more power than this truck. " He looked at the truck again, said "Oh, OK" and walked away disappointed.



Having said that, more BHP and torque in a stock truck IS nice.

DC just needs to totally up the bar and just put out the 340 hp, 700 ft lbs of torque output setup and be done with it! I sometimes get tired of these 5 lb increaces in TQ. But its still nice to be the one thats 5 lbs ahead of the compitetion!

Tomeygun,



So where is the x-tra 10 lbs of grunt coming from? What enhancements?

I have on good authority that dodge is using a thicker pen when plotting the torque curve on paper for the Cummins, which accounts for the extra 10 ft lbs. of torque. Everything else is the same.



(heck, it wouldn't surprise me one bit that the motor is exactly the same, and dodge figured that they would have to up the advertised TC to keep up with ford and chevy each year. . reminds me of the games they played in the late 60's early 70's with muscle car HP figures. I mean, come on, a big 10 ft lbs is a whopping 1. 67% increase from last year. Big deal. Its all to sell cars and trucks boys)

i think dodge needs to up it to 450 880 ft lbs

I would say it is from either:

1) raise rail pressure 200 psi

2) increase duration by one nanosecond



on second thought, i agree with the thicker pen idea

I always play golf with a pencil with an eraser,. . so why wouldn't a thick line pen work??

So what about the sun roof?

 

[klenger]

The sun roof HP has increased 10% and gets 12% better milage than before. Unfortunately, they had to add EGR to meet EPA specs.

At our dealership we have several 2005s on the ground with sun roofs. One is a 1 ton, 6 speed sporting the new color, mineral gray.

 

[KCJackson]

Raising the torque ditches the whole branding of the engine as the "Cummins 600"... And I was thinking about getting the old Cummins Signature 600 emblems for my 05.



Of course, if the rumors are true, there will be the stroked 6. 7L ISBe next year, and that will really spark the claims: "Dodge Ram, with the <B>largest, most powerful</B> diesel" - then you'll see GM stroke the Duramax a few cubes to catch up.



On the plus side, I can't wait to step out of my stock 180/420 12-valve and get into my 325/610 for a back to back run at the dealer.

If they'll give it 400 horse I'll trade. You listening DC???

Shortened life. Nothing's free!



But I'd bet there are no changes at all. Generally, engineering experimental tolerance is 2% for well-calibrated and well-run experiments. 10 ft-lb is 1. 7% of 600, so that is well within the limits of experimental error. In fact, I'd bet that on a dyno you can't get much inside about 5% error, so Dodge could probably legally claim up to 630 lb-ft without any changes to the engine at all (assuming the base engine really does make 600 ft-lb).



You must always understand that even experiments (i. e. hard testing) is imperfect and every measurement has some uncertainty (Heisenberg uncertainty principle).

I hate those things anyway - they burn my bald spot
