Just a thought, if they are not going to make the 5. 9 any more, will we still get after market support. Theres not to many 03's or 4's on the road.

Not around here, there's '03/'04 Dodge Cummins aplenty in these parts

maybe it's the same block and components, just punched out the cylnders a little and bigger pistons?

Enough of them for manufactures to invest a lot of money in product design?

Personally, I believe the reporter didn't listen to what he was hearing.



#1 6. 1 Liter is only 70 thousands over , why bother?



#2 The Cummins ISB already produces 600 lbs tourque out of the crate, but defuels at 2600RPM.



#3 If the same engine defuels at 2850 RPM, as it does in our '03 5. 9's, then it is 325 HP.



#4 The ISB already uses a VGT Turbo, which gives better low end boost by changing angle and volume, and is required for EGR. Both of which are headed for the TD.



#5 EGR isn't as bad as everyone thinks, yet



#6 EGR, as I have seen it, will be a fuel filter sized cannister with an electrically or boost/bleed operated EGR Valve that opens under low boost, high temp conditions, the kinds we avoid with large and VGT turbos anyway, and bleeds some exhaust through a radiator cooled cannister, that is then mixed in with the intake air to reduce oxygen and therefore combustion temps and therefore NOx without mixing Urea into the exhaust, platinum into the fuel, or using a catylyst.



#7 I think it will give more, not less, opportunity for Bombing, and will be very easily defeated.



#8 The ansswer to #1, why go 70 thousandths over, because 6. 1 is bigger than Fords 6. 0

Dieselman,

I agree with your comments, particularly the "why bother" going from 5. 9 to 6. 1. In fact, the only legitimate rationale for doing so would be that it is a completely different engine ! Sure hope this isn't the case.

As far as the EGR is concerned, I agree with you from an engineering perspective, but my concern was more with the AHJ's (Authorities Having Jurisdiction) now being able to legally prevent us from modifying our trucks by virtue of the illegalities surrounding modifying anything that happens to be related to the emmissions control systems. (ie. exhaust systems, etc. ). It might be easily defeated, but you might get a fine and an order to replace or repair it during a manditory vehicle inspection like the Aircare program here in some areas of B. C.

That story is bogus, that writer didn't hear what was being sad. The 6. 1L is the new Dodge Hemi not a Cummins



He talks about 600 ft lbs of torque, thats for the new 05 5. 9L Cummins output (got to keep up with the Jones's (Ford))



Look at this.....

Here is the current RV version B5. 9 with EGR and VGT...

Notice the EGR Rail over the front and where is the gear driven HPCR Pump?

if they put a cummins in a jeep and it has solid axles and looks cool i will buy it in 1 second. i only bought my truck for the cummins no towing nothing, i hope they do it along with the same axles in my truck now. that would be awesome anyone have pics of the jeep rescue?? now if theyd only use a allison trans
