isb to be 6.7 litre in 07

[RM]

a cummins broshure for emissions said this. also exhaust gas recirculation,crankase vent to intake. viariable geometry turbocharger. partical trap with a regeneration cycle. read about it here http://www.everytime.cummins.com/every/pdf/4103902.pdf down on the 3rd page of pdf

I admit I was really worried about all the speculation with the 2007 challenge. All the rumors of a V8 Cummins, V6 etc... Sounds like this EGR equipped ISB with Variable Geometry Turbo charger is going to be super clean, super efficient, super quiet, and have some seriously generous power gains. I bet GM & Ford are shaking in their boots right about now. I am willing to bet money this new ISB will have at least 375+ hp & perhaps 690+ lbs/ft of Torque out the box. And we all know Ford International/ Navistar will be so far behind in the wake, it flat out won’t matter.



Hey all of you running aftermarket exhaust on your 3rd generations trucks. The answer to removing the drone, add a Particulate Filter. Just kidding anyway I can’t wait.

Well, unless I missed something, I feel certain that our beloved Cummins is gonna grow a little--or maybe a lot Now... about the automatic transmission.....

 

[KCJackson]

My prediction for the Dodge version of the 07 ISBe will be a 375/675 rating... this gives them room to head up to 400/700 with little work, should the competition catch up.



If the 68RE (or RFE) shows up for 07 as well, I might have to think about trading up a lot sooner than before (almost 9 years). The next HD Ram should be introduced for the 2009 or 2010 model year, so I may have a new 2010 or 2011. That would give a year of the new body, and at least 3 years of the new powertrain.



The irony should not be lost that, from 1989 until now, Dodge used the smallest displacemnt diesel and easily took on all comers. In 2007, the Cummins will actually be the biggest (Duramax at 6. 6 and Ford at either 6. 0 or 6. 4 if the rumored twin-turbo shows up). And still only 6 cans under the hood... just REALLY big cans.



Now if they'll just drop the 4. 5L ISBe 4-cylinder into the Ram 1500...

Hey Beavis: He said "big cans"... ! :-laf



Matt - inline engines for life, although that Audi R10 V12 TDI is mighty tasty.

I thought the part about increased fuel economy on the Cummins .pdf was interesting. A lot of info coming out with over 1 year before intro. Wonder what the price of the Cummins option will be on a Dodge? Looks expensive.

 

[JoshPeters]

All I have to say is... . all the worry that people have had with the Benz Diesel giving the ole CTD the boot appear to be unfounded. This new engine sounds pretty friggin sweet!

I think I"ll upgrade in 08-09-ish..... depending on bombs, clutches, and new body styles all a big factor.



Tho a standard cab may be the choice then.

i asked the question over two years ago about the 6. 7 when i found out it was repacing the 5. 9 in agco tractors. no one had even heard of it they told me i was confused i was reffering to the hemi... ok?!



so with that said i believe cummins is trying make ford show their hand. i am sure for will try a new 6. 4 twin turbo and screw it up again. 375/400hp stock where does it stop???

 

[CumminsBu]

6. 4L Powerjoke Twin Turbo, sounds like a winner! How will Ford be able to afford that, They can't keep one functional turbo in the one they have.





If Dodge finally builds a Longbed Mega Cab Duely, 4500,and 5500!



We will see how strong costumer loyalty is, Ford?

 

[rjohnson916]

The only thing I’m really concerned with is the new EGR technology and Cummins using a Variable Geometry Turbo. I don’t think any manufacture to date has had great success with this design. Cummins is unique and more simplified, as according to the PDF reading, it only was the variable geometry on the exhaust side of the compressor. Still I know they don’t really have a choice, as the EPA is forcing ULSD and more stringent emissions, resulting in all of this overtly complex and unnecessary equipment.



Again I’m excited that Dodge & Cummins will be sticking with the inline six. This is about 80% of the reason I got a Cummins in the first place, as I didn’t want a complicated V8 turbocharged engine in a $40K truck.



I wonder if Edge, TST, Bullydog and some of the other aftermarket companies are already R&D the 6. 7 yet? I wonder if it will be more of a challenge to Bomb one of these new engines? I couldn’t imagine some serious race injectors and mods, clogging up a soot trap?

I'm sure there will be ways to bypass all this EGR stuff. remove it. fool any comptuers that monitor it in no time.

 

[CajunDieselMan]

True BOMBers to the core!! :-laf The new engine is still a ways off and you're already thinking of BOMBing it.

 

[amnewsom]

Biggest question, when its time upgrade, will I be able to? The cost of new trucks plus a bigger badder better Cummins between the fenders.



I plan on driving my 02 until the wheels come off - with the issues in my front end it might be before 75K miles.

Exactly the reason why I won't wait 9 years like I did last time. If I can keep the truck in sound condition and trade at a good time, I should get plenty of resale value to apply to the new ride. Between trade, rebates, and cash down, I put a lot of money down on the 05 so that I won't ever be upside down on the loan. I could trade it right now and clear $8000 minimum from the wholesale auction price.

Why are they doing this?

Lets discuss the reasons that they are increasing the displacement by more than . 1 liters/cyl. They say that they are getting a higher power/weight ratio and not saying anything about more power. Does that mean that they just increased the bore size? That would lower the weight of the block (maybe) and if the power stayed the same, the P/W would go up. I don't think they would increase the displacement just for giggles. They had to do it because they lost power in the emissions treatment. I guess they could have increased the stroke and left the bore alone, but I would think that you would have increased weight through longer crank arms (P/W decreases). Maybe the compression ratio is higher now (more efficient), but that increases NOx production. This engine looks cool and I hope that we keep hearing more news about it.

 

[chrleb1]

The bore is exactly the same, but the stroke is actually longer. The hp output may not be too much more, but the torque on these things is going to be massive. On the Cummins web page, the highest output was like 285/730. These are ag motors though. The thing i find to be interesting is that these motors are to have the rear gear train (makes quieter operation).

 

[CATCRACKER]

how much more quiet can you get?

 

[JasonCzerak]

how much more quiet can you get?

the new 2. 0 liter TDI are just a faint rattle.



Maybe my clutch is trashed that bad, and my valves are that outa wack. but my truck isn't as quite as it was from day one, once you try to eliminate the idle sound from the straight pipe.

 

[SHobbs]

Rear gear train? Don't tell me that well lets say the engine cover is leaking on what was the front which is now the rear, that would be a booger to fix.
