D-Max power level up

[BHolm]

Now I know that most here could care less about what GM is doing but I am surprised it hasn't come up at all. I think I read that it goes to 360hp and 650 lb/ft of torque and will be chanelled through a six speed Allison auto.



I haven't seen or heard of any comparable upgrades from Dodge yet. When is my 800 lb/ft CTD backed by a modern automatic coming? Could we be seeing something when the '07s come out since the '06s are pretty much the same as the '05s?

Old news. Someone posted the numbers several weeks ago. I too am waiting for a Dodge Cummins with a six speed auto, compatible with an exhaust brake, and a minor power tweak to keep abreast of the competition. I think GM was ****** when they thought they had Cummins bested with their 605ft. lbs of torque 05 D-Max, and when it surfaced, Cummins had gone to 610. Isn't competition grand?

Just Rumors that I have heard and read on here previously, Dodge is working on a new 6speed auto that I believe was slated to be released as a 2006. 5 model. I'm sure once the Dmax with the improved power rating hits the street, cummins and/or Dodge will change the program to accomodate 375 and 660 lbs of tq. or something like that.

Most miss the key point here though...



Ford & Chevy have to use 8-cylinders just to get anywhere near the Cummins I6. So to me it ain't a threat until they start pumping out at least 25% more than the Dodge. 650 lbs? What's that... 8%?



They're still a long way off from making any kind of huge breakthrough.



Don't take that for a bashing either, my Uncle has a 7. 3L & my friend a 6. 6L Duramax. Very nice trucks and I am in no way saying they are inferior... just stating a fact that they may make a lot of power, but they're 25% bigger engines.



And based off of my uncle's, getting 25% worse mileage.

 

[KCJackson]

More importantly, Ford and GM could care less about people who prefer to shift for themselves...



ratings with automatic trans:

Duramax (06, 06. 5) - 310/605, 360/650

Cummins - 325/610

Powerstroke - 325/570



ratings with manual trans:

Cummins - 325/610

Powerstroke - 325/570

Duramax - 300/520 <--same as the ORIGINAL Duramax



No choice at all if you prefer to clutch it.

No flame intended Jonathan but that must be "new math" you are using Two more cylinders does not make the engine 25% larger. The 7. 3 is about 25% larger than the 5. 9 Cummins but at 6. 0 and 6. 6L for the current competition, they are now roughly all the same size. The two extra cylinders can offer more valve area and better airflow. That makes me agree with your premis then that the others should be making more power based on the 8 cyl design. You are correct that they do not, and moreover we do get better milage and reliability.

BHolm,



Good point on my math mistake there. Didn't think about total displacement. However, you still got more injectors and so forth on the 8-cylinders more than likely shoving more fuel and burning more than the Cummins 6-cylinder. Is that a correct assumption or am I off there too?



To give more accurate figures:

6. 0L PS = 1. 6% bigger

7. 3L PS = 23. 7% bigger (which equates to about the mileage difference between mine & my uncle's which makes sense

6. 6L DM = 11. 8% bigger



So I stand corrected on the size point... but for years the 6-cyl has been holding it's own against the 8's, so that's gotta count for something.



Does anyone think Cummins is ever gonna go with 8-cyl to compete or is that just opening up a can of worms?

 

[BHolm]

If they intend to keep their current customer base, they had better just evolve what they have right now. Cummins has done a very good job of raising the bar so far, hopefully that continues.

8 cylinder? Why? There's no need. Six is the right amount of cylinders if you want to make a torquey motor. How many big rigs are running V motors any more?



Side note: At the HDDR event there was a 1969 3-axle conventional rig with an old Detroit 12V71 two stroke with stacks through the hood, complete with NOS. Dude did a 13. 5 second quarter. My jaw hit the floor when he spooled at the line. Day turned to night, but at 60 feet he hit the NOS, smoke turned grey and he was GONE!

I'm curious as to the type of transmission those trucks are running. Pop the axels into hi, and just run with 7 or 8th gear? Some sort of powerglide transmission?

 

[MHorne]

Just a question about the duramax. My brother in law who is a chevy fanatic, poor soul, told me that the duramaxs were putting out too much power for that allison transmission so they were gonna reduce in power. Now at first i thought that there was no way in hell that transmission couldn't take that power but like i said he loves his chevys. I think its bull crap what hes saying but is he right.

 

[Schicken bone]

ford owns cummins, so what happens when you cant buy a dodge with the ctd. do we all go to ford. this will happen because international and D max (cant think who makes them right now) cant keep up. i might be wrong but i believe this will happen. just my o2. bone

 

[RMalone]

cummins owns cummins.

 

[Schicken bone]

then why i 07 or 08 ford will have cummins

The Dmax does indeed de-fuel at certain shift situations.

 

[MHorne]

just what i've heard but those mercedes that they might be considering is a superb motor. I think it is pushing either 700 horse or torque in europe. I also think it will be an elite motor if it comes into the U. S. market. However letting go of the ctd would be a big shame. I love my motor and would want the ctd over the mercedes anyday.

 

[Schicken bone]

i agree. but i also think that ford knows it will not be able to keep up much longer, also the d max as well. i still cant think who makes the d max, please somebody tell me. bone

 

[klenger]

Well, I went look'n for the FAQ at the Cummins website that states that Ford does not own Cummins. Guess what, ... it's not there anymore. Maybe Ford does own Cummins now. :-laf



Found it.

 

[MHorne]

isuzu makes the d-max and where is it that it says ford will have the cummins in it.

 

[RVTRKN]

If ford does go to CTD, (its rummered) that shows dodge has the best
