The 2007s Are Coming!

Attention: TDR Forum Junkies
To the point: Click this link and check out the Front Page News story(ies) where we are tracking the introduction of the 2025 Ram HD trucks.

Thanks, TDR Staff

Intake Manifolds and boost bolts

EZ and fuel rail pressure...

I was having my 03' serviced at dealer in Ogden Ut. Was told by the dealer that the factory Rep. (Sales Rep. not Service Rep. ) informed them about the 2007 models.

Quote; "Will be 6. 1 engine, Hp and Torque will remain the same for now. It is expected that the engine can put out 800 lbs of Torque for future increases. Or for those who what to chip it up. Will have 6 Speed Auto"!

I sepect that this 6 speed is the same transmission used in the FL's with the MBZ engines. If it is it is a sweet transmission. Having a padel on the colmun that allows you to work fully auto or manual by pulling up, to up shift or down to down shift! When I asked about the 4500/5500, I was told that the factory rep did not say.
 
Hope the guy isn't mixing info on you there, the 6. 1L wouldn't happen to be the new bigger Hemi in a truck version of the 6. 1 offered in the SRT's?? Seems like if they were going to do a diesel redesign, they would increase displacement by more the '0. 2L or 15 Cubic Inches wouldn't they?? :confused:

Or they made it a v8 and ended up at 6. 1... :(
 
The '06 D-Max

My new Truck Trend for Sept/Oct says the '06 D-Max will go to 360HP and 610 TQ. Also the new Allison will have 6-speeds. Looks like Dodge is late to the game.

The Cummins is already stroked to 6. 7L in the agriculture segment. It's the motor that will be in the 07 Ram.

Here is a media release on the 6. 7 Liter Cummins Engine. Pretty interesting.



Here is some text from the AGCO Tractor Site:



[size=-2]A Powerful Business Advantage



RT Series tractors feature 6. 7 liter Cummins engines that are built and tested to the most exacting standards in the diesel engine industry. These fully structural engines, specifically designed for the agricultural market, are incorporated into the tractor frame itself and deliver more power than ever before — from 100 to 150 PTO hp.



The single-piece cast-iron engine block incorporates a stiffened ladder frame and reinforced webbing. Also, the reinforced, large-capacity oil pan forms a structural unit with the block, further enhancing the inherent strength of the engine design.



So, how does this help you? The improved structural design provides more durability and reduces vibration and engine sound levels. In addition, the structural improvements combined with an exceptionally narrow configuration improve the overall design of the tractor. This makes it possible to achieve a much tighter turning radius {up to 20% tighter}, giving operators more flexibility and a better line of sight. It all adds up to increased tractor — and operator — productivity.



Improved Fuel Economy, Lower Emissions



The high-efficiency combustion chamber design of the Cummins engine is perfectly matched with the Bosch mechanical fuel injection system. The result is improved fuel economy, excellent cold-starting capability and lower emissions. The Cummins engine also employs a unique wastegate turbocharger to use fuel more efficiently and features advanced technology in the lubrication and filtration system.



RT tractors also feature economy PTO {RT100-RT120} to help reduce fuel expense and increase tractor productivity. Economy PTO allows the engine speed to be reduced by up to 23%, from 2000 rpm to 1550 rpm, yet maintain full PTO shaft speed. Slower engine speeds reduce fuel usage, noise and vibration. [/size]



One year later than GM. But from a PR standpoint I don't really know that being 1 year behind in power to the Duramax is as bad as it would be if they were 1 year behind Ford... . I'd only own either the Ford or the Dodge.

Yes the 6. 1L is of course a Stright 6! I feel that if they use the MBZ 6 speed Auto/Man. shifter this should be a big, big edge over both the Ford and GM. Mostly because it will give the driver the ability to shift Manually or Auto, and it is alot more user friendly. That is if they actually use the the MBZ trans!

Atleast DC has one advantage over the Ford and GM, the Cummins Engine... . :) And Ford does not own Cummins. That died when Ford could not use the Cummins engine in their own vehicles, due to the contract with DC... atleast that was my understanding when this issue came up about two years ago.



I Have to agree with JGann, that being a year behind GM is not a bad thing. Plus based on GMs track record when it comes to Diesels, I would not be surprised that the Duramax is going to end up pushing its limit very soon. Especially since it is not considered a heavy duty diesel like the Cummins. Of course that goes with out saying for the Powerstroke.

Thanks for the link to those 2 new Cummins engines. That 6. 7L I6 is the logical choice for the Ram HD's. Its rated at like 275hp for a tractor application, should be no problem pulling 350hp and probably 700+ft-lbs of torque in the Ram application. That 4. 5L I4, rated at 170hp in the tractor sounds like a nice little engine for Dakotas, Ram 1500 and Durango. Crank that baby up to 250hp and 400+ ft-lbs and you'd have a killer little engine.



Cummins also has that 4. 2L V6 and 5. 6L V8 that has test data in a Durango which looked extremely promising. My buddy (a shop foreman) said that the guy giving his DC classes said diesels are coming in the future much more, including cars Oo.



The future HD transmission, whatever it is, needs to offered with a Center console shifter and Autostick!! Best of all worlds there!!
 
6. 1L? Yep this is about the 3rd time it's been posted on TDR the next Cummins will be a 6. 1, the source being confused with the 6. 1 Hemi.



The 4. 5L B-series 4-cylinder is the stroked version of the 3. 9L B. So it appears the 6. 7L will have the huge lunging 5. 39" stroke the 4. 5L has. The 5. 9 & 3. 9 are 4. 72" stroke.

Long stroke = higher torque doesn't it?? Should be a great thing!! Maybe 700 ft-lbs as an estimate is too conservative on my part. . :-laf
 
the 4 cylinder B series will never make it into a production light pickup truck. it isn't refined enough for the general automotive market. and marketing would have a hard time pushing a 4 cylinder. the 6. 7 is a good engine, but in pickup truck application i don't know how it well it will work. it's taller, heavier. engine is longer stroked a bit and we already turn about 1000 rpm more than the industrial application of the engine. having it turn 3500rpm might be pushing the internals of it a little harder than cummins would want it [although they don't warrenty it, DC does so who knows???]
