Ohhhh Mannnnn...........'07 Ram 6.7

[EMD-Run8]

Well, I told myself I wasn't buying anymore new trucks but that 6. 7/Aisin 6spd auto looks like it's gonna be a real Mac-Daddy combination. I'm really not crazy about MORE electronic stuff but it's only gonna get worse from here for new diesels. I'm bettin' that 6spd auto is gonna be SWEET. I wonder what HP/Torque rating the 6. 7 combo will jump to when the '07. 5's come out. So far not seein' much comment about this truck. What ya'll think?

 

[EBung]

One web site I read said the ISBs will be at 325/750.

So far all we know is the first allocation of Heavy Duty Cummins trucks for 2007 will be a 6. 7L rated at 305/610. There is no doubt in my mind more power is in the near future, but I don't think it's coming in the first run of the new trucks. D/C spent a lot of money in the facelift and interior changes for 2006, and even more money to comply with 2007 M/Y emission regulations. The current trucks are good enough to carry Dodge another year with strong sales while GM tools up and drops an all new truck out, and Ford goes through the likes of more trial and error with their new 6. 4L. Only time will tell for sure.

I don't want to sound like a Flamin' Greenie here but it seems that most of all the added complication that is coming in the new diesels could be done away with if some other cleaner burning fuel was used like Biodiesel. I also read the other day about a "clear" diesel fuel that is butane based that is currently being worked on. These motors are REALLY getting complicated. I dunno... .....

I hope all you guys that are waiting on the 07,s are right about this new motor/trans combo being the next best thing. I heard and read about all the changes and jumped on my first Dodge,an 06 Mega 2500,figured it would take a few yrs to get all the bugs worked out of the new set up.

NO kidding. The problem is that we're burning fuel with all kinds of nastiness in it.

The emissions system on these trucks are almost like having a sewage plant in your own home. You start with dirty junk, yet you're supposed to have super clean waste output???

Diesel should be CLEAR imo. I've seen a lot of biodiesel that looks like water (only thicker).

But of course we can't get it, because that might make farmers some money instead of the oil barons.

ULSD is a step in the right direction, and I'm excited to get it.

Buyt ultimately, a super clean fuel like some GTL stuff or super-refined bio is going to be best.

I agree with Patriot Blue Megacab. I just got a 06 (Blue ) QC to avoid all that new stuff. I feel like the 06 will be be last of the great diesels, especially if you want to bomb or work on your own truck. EGR, closed crank case, particulant trap, etc. , not for me. Very complicated engine in 07. 6. 7 litres sounds great but at what cost. A simple box puts the 5. 9 at the same horse power. I also think a DTT'd (or other vendor) 47/48re is as good as it gets. The Aisin maybe good, but it's new and complicated. The GM/Allison isn't all that great and it is very expensive to up grade or work on. Time will tell how the new engine/trans works out. On thing for sure, its better than the GM/Ford alternatives.

Seems like the same thing was said about the 12v trucks in 98, the 24v trucks in 2002, and the 305/555 trucks in 2004.

 

[EMD-Run8]

Your right Klenger but you gotta wonder where it stops. My '04 was fine---basically straight high-pressure electronic fuel injection. Then we went to an electronically controlled wastegate and a CAT----still OK. Now in '07 we're going to a closed-loop crankcase vent, liquid-cooled EGR, variable-geometry turbo (which is admittedly very cool ), a liquid-cooled particulate trap which the engine can self-clean by raising EGT to a level that I guess incinerates the particulate, and a CAT. Now I have no doubt that Cummins probably has one of , if not the best designs/setups and this engine has already been in use since 2002 but whssshhhhheeeeeeewwwwww! Rumored in the future is Urea ( What? ) injection, I think for controlling NOx. My point is that with cleaner fuel, some of these steps might not have to be taken like the cooled EGR and particulate trap. Then again, I'm probably dreamin 'cause the EPA would probably find something else to justify it then. I guess it's just me.

I dont see whats so wrong with buying a 12 valve or doing a conversion and stop complaining about all the damn electronics, the epa tree huggers cant do anything about a truck that was built to emissions standards back in the 90's. I love being able to work on the mechanical simplicity of my 12 valve and every time I look at all the electronics on a newer diesel it makes me sick to my stumach, then i remember my truck and it makes me happy.

 

[JasonBrown]

That's why I'm keeping my '05 at least 20 years. It lives in a heated garage, and so far 8 months and 6,000 miles. Then again, maybe 30 years.

 

[Hohn]

So, how are they going to implement the urea injection? Are we going to have to pull over to pee in a separate tank?

jh

 

[EMD-Run8]

I guess!!!!!!!!!!!! :-laf

i too have wondered how they will make this work, as they will loose money on something like this. . it will need to be constantly filled [every few months] to keep the system working, and customers will not pay for something that will not effect the engine running. that will need to be something that the dealers would be required to supply for free [or included in the vehicle price like a 10 year supply contract with manufacture]

 

[Steve St.Laurent]

Or have something built into the ecm that will not allow the engine to start unless the system is functioning.

 

[klenger]

At the rate I am putting miles on my truck, it will be another 80 years before it has 1M miles on it. I'm 55 years old. You do the math.

Yep. Ditto that.

It has a sensor in the exhaust, and if it's out, it will probably go to limp mode.



Urea is better since it uses advanced timing (good mpg), no EGR, no particulate trap, no diesel injected into the exhaust, no exhaust backpressure sensor, just a catalyst and urea injector (like a propane bottle). How hard can it be to trick that one?

The justification American manufacturers (Cummins and the rest) gave when they chose the route of particulate filters, was that diesel in the US was not expensive enough at the time ($1. 20/gal?) to justify the urea system. Once they went this route, it will be years before they change, perhaps in 2011. By that time emissions will be so strict they will probably need to add urea to the present mess just to pass EPA.



On the other hand I looked at the MB Bluetech, and it has 4 catalysts, and it looks like urea too :--) This is for a car though, and emissions are tougher there.

In order for me to get into a 6. 7 anytime soon, Dodge is going to have to wrap it in a Mega Cab Long Bed. I'm not holding my breath!

Add to that a 10 year 500,000 mile warranty with no more than a $100 deductable. By the time you would get to 100,000 miles on those new engines and exhaust systems you probably will spend enought $$$ in repairs to has purchased a new Honda Civic.



Maybe DC can just sell the truck with a engine delete ... then install "old" used 12 and 24 valve engins in there.
