Ok guys I just saw a comercial for the new Dodge and the add stated that they have 600 ft. lbs. of torque. The only place I can find torque listed for the Duramax is in the sales brochure and it says 520 for the (LB7). No mention for the LLY. Any helphttp://www.dieselplace.com/forum/smileys/Confused.gif

the LLY is 590 ft lbs of torque

The LLY is 590 ft-lbs with the Allison, and 520 ft-lbs with the ZF.

And those are fly-wheel engine stand #'s. Ask ford how they advertise the highest hp rating but somehow only produce 230 at the rw, the lowest of all three big guns.

But of course its FW Stats!!


They wanna give you the highest numbers possible!! BHP and BT are, from what I've seen, about 20% lower.


This should be what your looking for :

Thanks to all that responded, the info was very helpful.

From the stock trucks running on the Dyno that I've seen they put out about 235 - 245 Hp at the wheels and about 405 - 425 ftlb of torque.


With a Hot juice they go up to 365 hp and 685 ftlb of torque.


But thats LB7 hopefully we will see some LLY this summer at the Dyno with a box or two.

Hmm.. "Hot juice" doesnt sound like a chip even though the numbers indicate that.


What is it?


Ram

If we test our trucks without the CAT, how much do you think the torque would go up?

Hot Juice is Edge product.


There original Juice was 90hp and then they came out with the Hot Juice which was 125hp and now I think with there new in cab controller there up to 150hp. Super Hot Juice I guess http://www.dieselplace.com/forum/smileys/Wink.gif

590 ft. lbs. in 2nd,3rd,4th gears only.520 in 1st and 5th.............JB.

Where can I get the torque in high gear specs in writing? According to the dealer I bought new truck from today this info is incorrect. I will be upset if my new truck does not make advertised power in high gear.

Its on the gm site

Its on the gm site


I have searched their site and can not find it. I also picked up the latest brochure yesterday and it says 590 with the Allison.Edited by: RickDLance

I think JB is correct.


I've done a little searching on the power restriction thing in two gears with the LLY. I can't seem to find it right now, but it seems to me I've seen that somewhere. I think that's part of the reason you'll see the new Allison line up with higher HP and torque numbers they've announced. Unless you're drag racing, there's not much need for max power in first, and fifth is the weakest gear on the Allison.


Even Edge posts numbers showing the max torque the Allison can take is substantially lower in fifth than the other gears. IIRC, it's something like 25% less in fifth gear than in second, third and fourth.


I may do a little more digging today and see if I can come up with the source...http://www.dieselplace.com/forum/smileys/Geek.gif

JB,


That's not an article I had seen, but it's a great write up on the LLY and talks about the power restriction as well as the other changes in a very clear non technical way.


Thanks...http://www.dieselplace.com/forum/smileys/Clap.gif

This is a pic of our LLY 4500(Still waiting for the RV hauler body to be built)........JB.

I second Zeeb.. Thanks for a great article!!


Quick question.. Other than noise reduction, what purpose does the "dead space chamber" have?


Wonder if it reduces performance any (With a turbo it probably doesnt but what about otherwise, in a normally aspirated engine?)


ram

4500 lly, nice looking truck! Is it an allison or 6 speed? I'll be interested in what it weighs once you have it outfitted.

My company may need to upgrade to this sort of towing rig, our trailers keep getting bigger and heavier. All of our rigs are manual trannies, we do about 50K mi/year at 20-24K gcvw.

Sub,
It has the Allison trans.The shipping weight was 7400 lbs and the bed will weigh around 1800 lbs.It sure is different from my D/Max 3/4 ton I had..........JB.http://www.dieselplace.com/forum/smileys/Big Smile.gif

Do they put a 6 speed Allison in that? I thought I read that they do.

I think in the 6500 series they do,,,,,,,,,,,,,JB.
