so are there any upadates on the 6.7?

 

There should maybe be more about the 6.7 Cummins tomorrow. 610 ft/lbs is lower than expected, but this might not be right, or it might have something to do with emissions.

 

I bet it has to do with emmissions if it is the final number. The 6.4TT has been so far rated at 650 according to the document released a while ago.

It is very hard to build an auto to take that much torque. Especially when considering the size constraints. If youve ever seen a medium duty transmission designed to take 700 lb ft youd know they wouldnt fit in a pickup. I doubt Ford nor Dodge are gonna let Chevy be in the lead for long. We been playin leap frog for too many years to stop now.
The reason they increased displacement was to not lose hp during this latest emissions phase. So it is feasable that ratings would stay the same even with the increase. I think it not likely though. Too much rivalry going on in this very competitive market.

 

huh? the current 5.9 is rated at 610.

 

i know. 610 and a lot more displacement.

700lb feet is not hard to hold in a transmission, they could make them hold that kind of power from the factory if they wanted.

their are plunty of guys that are changing the torque converters and clutch packs in the allison and are holding over a 1000 pound feet of torque. the tranny is not hard to do. emmisions is the hard part.

 

Take another look at that link that I posted. The full report is now there.

 

It is hard to do otherwise Ford wouldnt be bringing up the rear.

 

There have been fairly reliable rumors putting it at 700 lb ft. So it is lower than the rumor mill had put it. 610 and 305 is slightly closer to the ratings you might see in a medium duty. Mediums are governed lower. You wont see one making peak hp at 3300 rpms.

 

The idea of a 610ft.lb.tq doesnt sit well with me. Although i dont think i would buy a 2007 dodge brand new due to its new motor, thanks to ford and it 6.0 fiasco i will never by an untested engine again. Even as it stands untested it doesnt make any sense that the 6.7 would push the same ratings as this year. I guess we will have to wait and see.

 

that's what i thought. the new motor would atleast make old standards. i was thinking 400hp/700lb ft. those are the same expectations i have for the new PSD but hey its cool if they want to make the new PSD 305hp

 

When did it ever say the new PSD would be at 305 hp?

 

I'm still curious about the supposed Ram 4500/5500 trucks. I still haven't seen anything. Sounded pretty convincing on Allpar.com. I'm guessing that was just a vicious rumor perhaps?

 

If, the new CTD is rated the same as the previous, then its obvious they are setting it up to increase output in upcomming ram models.

 

nick it was [sarcasm font] i really don't think that the new PSD will be 305hp......sorry if i had you all nervous lonely and depressed.
