On the agricultural/industrial side, Cummins stroked the QSB 3.9 and 5.9 engines to 4.4 and 6.7 respectively. They are not "sisters" to the road-use ISB block, but they are related. Allpar had a data sheet up a while back with all current Chrysler engine codes, and underneath ETC and ETH was a listing "ETJ - Cummins 6.7L". My guess is, the 6.7L would be the new Jan 1 2007 engine, used in a 2007-1/2 Ram along with the new HD automatic - rumors there are 58RE, 58RFE, 68RE, 68RFE.
(Considering where these torque numbers are going, I might feel more comfortable with a "9" instead of an "8".)
Depending on what the competition offers, my prediction would be a rating of 375/675 unless someone (Toyota's 2007 3/4 ton?) forces their hand to 700 lb-ft. KC

It unfortunately might also be that Cummins has had to increase the displacement 14% just to make up for the bad effects of EGR (exhaust gas recirculation) coming in order to meet the coming very stringent CARB and EPA regs for NOx pollution.

In Diesel Power mag, they hint at a V-8 Cummins in the near future. I searched all over the web and couldnt find anything.

Why why why....don't in-line engine designs provide more torque per unit of displacement than v style engines? Well i don't know....most semi's use inline, and from what i've just read i guess most locomotives us v-style. Whatever they do i hope its just as powerful, simple, and efficient as the CTD now.

My 5.9 Inline-6 has at least as much as maybe a little more than the Duramax 6.6 V-8...

The Benz diesel will be the option for 2007 and probably be the only diesel offered for 2008, that was right from an engineer at the DCX R&D center in Windsor

dodge really needs to do something bout the low end, need an extra gear or two be better, and the turbo needs to kick in quicker and spool up, a 6.0L could take a cummins in the low end but the top end is mostly cummins.

Straight-6 is the most used diesel engine design. Caterpillar pretty much exclusively builds Straight-6s, it is the only engine design that is naturally balanced and has a power stroke on every single rotation, therefore creating more torque. I've operated HE gear with Straight-4s, Straight-6s and V-8s and the Straight-6 is by far the most versatile of the engines and creates the most power where it's needed. However the manufacturer's can play to the average person's lack of knowledge on Diesels and market a V-8 in the trucks successfully.

Amen. If ppl would only take the time to know some things, not just 'derrr....v-8 sounds cooler than straight six (or in-line six)'. I had (well have, just kinda broke...seems like those ball joints and wheel bearing couldn't handle the romps across the prarie) a 85 F150 w/ the 4.9 L6 (or aka 300-6) 4-spd. It roared and got horrible gas milage at highway speeds, but damn it was a torqy ******* good for muddin and snow.

The I-6 and the V-12 are pefectly (naturally) balanced designs, reuqiring no balance weights on the crank or balancing shafts of any kind. Now...if Cummins wants to develop a V-12 for a 3/4-1 Ton Pickup...count me in!!! :D

Yeah, I was gonna say that too, on our 6 spd, you cant really get much more than 10 mph in 1st gear and you are pushing the 3K mark. Plenty of low end grunt.

You have got to be kidding...this is a joke, right ? :crazy:
Ever try a zero throttle start in 2nd gear with a PowerChoke or DuraKrap ? Even 3rd gear ? They fall flat on their faces and almost always stall.....The CTD has more torque off idle at a lower RPM than the DuraKrap or PowerChoke. I have a friend with an F-350 4dr 4x4 DRW w/6.0L & six speed, and he admits it's a dog (he hauls cattle with a Gooseneck brand 28 ft. livestock trailer). He's often commented about his mistake switching from the Dodge to the Ford many times. The PowerChokes and DuraKraps work best with their auto's.....as for the turbo spooling, the little HY35 used on the 3rd GEN trucks spool quite quickly. There are so many more upgrades for the CTD equipped trucks than the PowerChokes & DuraKraps, too....all at lower pricing and easier installation.

well, if thats true, then the diesels work even harder b/c there is engergy loss from mechanical to electrical back to mechanical.

I can verify he is right. The diesels are turning the elecric motors. The electrics prodce a crapload more torque and is required to get those loads moving. So take that! :D

A report about the Cummins 'Light Truck' V6 and V8 program partially funded by the US Energy Dept:
I doubt we will see a stroker cummins in a pick-up, The longer stroke will make the engine taller and a little more delicate for us go fast drivers. If you install a chip that stroker could very well throw a rod. Tractor engines have a lower horsepower rating because by design they are intended to run at full throttle all day long because they are used to run Hydraulic pumps rather than a mechanical drivetrain. In other words no gas pedal!

There is definitely a throttle pedal on the Tractor that I operate. I haven't found anything that doesn't have some sort of throttle on it. That includes all of my fuel Pumps, from 125 gpm all the way up to the 600 gpm.

I had a 99 cummins and when my wife gave me "permission" to get a new truck I had my eyes set on an f-250 king Ranch. From what I head the Ford was the top!! Well I was set on it until I drove it!!! There must have been a misspelling on the emblem, "PowerSuck" is more like it. I believe that the in-line motors produce more torque so. I went to the Dodge dealer and got the 05 Laramie with a 6sp. I'm sure the 6.7 will be an Awesome drive!! :rck:

Having some sort of throttle and a throttle pedal are two different things... a pedal you actually push down on for the throttle whereas is the case with our old tractor, you had a throttle lever you just turned up to turn up the rpms. Other then that, there was a gear selector, clutch and brakes.
Saint
08-07-2005, 12:55 PM
I see what you're saying, about the lever the Dozers I work on have a Decelerator lever. I use slightly different tractors then what's seen on a farm, and they have an actual throttle pedal.

hey raj, this isnt mean to sound like im picking on you or anything. just giving an opinon, and because of the slippery past few posts ill try to be as cordial as possible. first off, the dodge cummins with the 6 speed is sick!!!! we have some hunting property in the foothills of the blue ridge and we have some pretty steep hills on the property. just got back from our yearly bash and there was one of each diesel truck there. i drove them all picking up wood and dropping people off at the lake, but the dodge ram was the only truck that would idle up these hills. i could, no shit, ease off the clutch with no gas and iddle up these hills in first gear. the power stroke made it a lil ways but with no gas was choking pretty hard and the same with the chevy. the dodge is sick and the 6 speed is definitely the best mate for the motor. i will have to go ahead and disagree
