anychance the new 6 speed auto will bolt up to a 325? or would it even be worth it?

 

20% mileage reduction is a bit to much , it is more like 7 to 8% less, Yes it will have a DOC "diesel oxidation filter" and a PM filter "Particulate Matter filter", engine will have the VG Turbo and EGR, You wont be able to just remove the DOC or PM filter like we use to because the ECM is taking reading from them all the time, the DOC will be kept hot by using multiple injection events like the 600. The PM filter is said to be a lifetime filter, dont buy that for one second, because you cannot eliminate the byproduct of burning carbon which is ash, they will have to come off and get cleaned.

 

I thought I read on the Cummins website that the new 6.7 diesel is supposed to have like 750 lbs of torque, but still only make 325 hp. True? Or was I reading under the medium duty section of their website?

 

please explain Hogged out 5.9?? Are they using the same block and changing bore size?? Or changing to a longer stroke using the existing bore size???

On a different note Ford started making the 07 superduty this week and are using the 6.0 January 1 they start production of the 08 model with the all new 6.4 powerpuke. Mabey Dodge will do something like this.

 

What we've learned about the 6.0 powerjoke is that we can disable the egr via a tuner, as well as stimulate certain sensors etc for tests. i imagine we can perminantly stimulate them (ie for the PM and DOC filters) with a tuner. Maybe we can do the same things with the 6.7. Disabling the 6.0s egr system actually makes the truck run cooler, and smoother without the stupid egr failures...

Amen, Brother !

 

I was a diehard Ford Man until I got stuck with my 04 PowerPuke. Three failures of the EGR Valve, Wiring and EBP sensor and I was done!

As I have no idea on the new Cummins engine I can not for sure back up what was said but here goes.

Hogged out means the bore size has been increased. Strocked means the stroke is now longer.

So I assume that the extra cubes come from a bore job.

 

I'd say it's just bored out too: 1st, it's limits tooling/manufacturing costs since there's only a few new parts (pistons, rings, head gaskets), 2nd because the larger bore would help unshroud the 4 valves - always a plus with that dang EGR! The difference is probably 7 cubic inches/cylinder, so you're talkin' about an increase in bore diameter of around .250" - anyone have a dream wheel handy care to weigh in? I just pretend to be a rocket scientist...

 

It would have to be more a little more than 7 cubic inches per cylinder, but its pretty close. I think it would increase by 8. 5.9=360, 6.7=408, and 6x8=48, so 360+48=408. I'm not sure if they could bore the block out to 6.7 without causing some kind of cooling issues. I'm not sure about diesels, but increasing the bore on a gasser .25 inches will create some very thin cylinder walls, which leads to a very hot running engine.

 

Thanks - I can never get those SAE/metric conversions memorized!

I'm pretty sure the cummins short block is just massive, so I'd guess there's plenty of room for a quarter inch bore; and I thought that cummins already made larger commercial diesels in the same block size. Heck, my '65 GTO block size supports displacements from 326 up to 455!

 

As I recall, there is also an ISC 6.7L that is used in stationary, marine and off road apps, but it is a different family. The new 6.7 ISB I believe has the same stroke but larger bore. I would expect that the block is a new casting, but probably identical in outside appearance.

 

My guess would be that it's bored,& possibly stroked.The ISC ebgines are all 8.3L.So it deffinitly can't be one of those.It has to be a modified B series.I's also going to be rated @ 305/610.For my money,I'm going to stick with my ISB 5.9 for about 1/2 a million miles,& then think about what to do then.I'll probably reman it myself,& drive it for another 1/2 a mill.

 

mmm...ive had an injector fail, turbo, egr and various other small things like the radio fritzing out and crap...ive had it! worse of all...my 6.0 just turned over FIVE THOUSAND MILES! thats it. im done with the bs.

Gentlemen, the details on the 6.7 were posted months ago. It is both bored and stroked over the 5.9. Also the Aisin auto tranny will only be used in the cab and chassis trucks NOT the pickups. The Dodge made 68RE (6 speed) automatic tranny will be replacing the 48RE when it's retired.

The 5.9 will probably be used for the first part of the 2007 model year, and the 6.7 will be introduced Jan '07. It would make sense to put the 68RE in then as well, but it may come later, I've seen no confirmation on it's intro date.
