i dont see this being plausible just because GM cares somewhat about gas mileage and since there are new standards being set, they probably will be working on gas mileage

that's fucking forever away. i heard the 2015 gtr is gonna pull a 1.9 60' instead of today's slow 2.9 60'. 900 wtq on an oem duramax=maybe 13's, probably not.

The current Dmax makes 797 ft lbs. Ford makes 800 and Cummins is stuck at 650 because Dodge won't build a better trans to handle more power.
With a simple programmer, 900 ft lbs is an easy $500 away. The problem, and this goes for all diesels, is #1 emissions. We can't have a puff of black anymore, and all programmers will put out some black smoke, some more than others. Not a big deal to us, but to the EPA, it's huge.
#2 is the transmissions. They simply are stretched as it is. Can they put a stronger tranny in there? Yeah, but it will raise the price even more, plus there are packaging issues since they have to be bigger to handle more power.
If they have this stuff solved, I don't see any reason why the next gen dmax won't make those kind of torque numbers. Not HP though, that's too much HP for that little torque. HP would probably be around 475.

Not that I know of. I havent worked in that program since June. Everything was/is still just on paper that I know of....but I dont exactly keep up.
People dont just leak stuff like the car mags/auto blogs make you think. People will make stuff up or 'leak' what they heard from a supplier or friend of a worker, but usually its way off.
Now, back to my 2014 planning session...

It's really nothing to brag about, any modern diesel can make 900 ft lbs all day long, maybe not out of the factory, but so what, spend a few hundred bucks on a programmer and there it is. The limiting factor is never the engine. If Cummins had their way, they'd probably have 900 ft lbs in the current truck, but due to emissions restrictions and Dodge's refusal to build a decent transmission, they can't tune it to that level.

Considering the GM and Ford engines JUST had a major overhaul for this model year, Im guessing Cummins will be coming out with the next big jump in a year or two.

Very unlikely!!! All the big companies are going to be hitting a wall. How much power and torque can they provide safely with good economy. Seriously, how much power is needed in a diesel pick-up truck??

The EPA will stop that with all of their regulations: filters, computer crap, etc.
Sure it will be possible with some type of programmer.



PLUS, that HP amount does not coincide with the torque amount. HP should be like ~450.
If, the truck is released with those numbers then it would actually need to make like 730HP and 1000ft-lbs trq because it will have to meet EPA guidelines.

Hell, 2013 EPA regulations are going to be bad enough.

Look at CAT! They stopped making over-the-road diesels a few years ago because they did not/could not conform the EPA's rules.







BTW, is ford and chevy really at 800 brake ft-lbs of torque this year?

Well..... The EPA has cleaned them up a lot, which is why all the new ones don't puff a bit of black smoke stock. But guess what,t hey're still more powerful than they ever were. Just like when they cracked down on cars in the 70's, for a while they were restricted, but once technology caught up, it more than made up for having to run cleanly.
The more efficiently they run, the cleaner they burn and the more power they make. They can make as much power as they have fuel to burn, the key is getting rid of the nox and soot which they are doing with the DEF and DPF.

How much power is needed? AS much as we can get, the more the better! Kind of like asking how much power is needed in a car we drive to work every day in rush hour traffic....

And yeah, ford and Gm are at 800 ft lbs bone stock right now.

GM is at 765 ft/lbs, Ford is at 800 (with a 100% brand new engine). The biggest number usually sells the most trucks. Numbers will keep climbing for a long time coming, and the sky is the limit, trust me.

That was only part of it. The last few engines they made were total crap. My dad bought a new Peterbuilt with the last year Cat with egr/dpf because he got a great deal on it for his fleet, and the engine has had major parts (head, pistons, ect) replaced at least 3 times in just a few years. The thing is a giant turd. Detroit Diesel is making money AND meeting EPA standards....so why couldnt Cat?
