2010 duramax 6.9l

[03 D-max]

-this might be a stupid question but-
I know in 07 there were some rumors of a 6.9 425hp duramax and wondered if their was any more info about it or if it was just rumors because i havent heard anything about it lately?
Thanks,
Jacob

I was pretty sure its going to stay 6.6?

I bought a new Lmm in early September, I ask the salesman if there was any upcoming changes for the 09's he said No not really the only thing different was that they was offering them with Bluetooth Tech. However 2010 there is rumor that the truck will be a 6.9 with 425plus hp & 700lbs trq.


But this was a salesman telling me this!

I BELIEVE THE 4.5 WILL BE AWESOME IN A HALF TON.

"The Ulti-max", been rumors for a while, nothin substanciated as far as i know. I think they should just bump it to 7.0L

but 6.9L has a nice "salt in the wound" ring to it huh:rofl::rofl::rofl:

Im pretty sure the 6.9 is for sure because there was some inside guy on another forum that gave us a little info on it.

Everything I've heard is that it's 6.6L and equipped with urea injection and if the rumors are true.. twin turbos.. much like the ford.. tiny

my dad hates his 6.4

 

[WolfLMM]

If GM is still around:rofl:

 

[durallymax]

I hear 425hp 770lb-ft staying 6.6L, 3 gallon urea tank possible twin turbos. Lets of headaches. But at heart still a Dmax.

Anyone here have much knowledge on the whole urea system? Will we be able to by-pass it like the dpf?

 

[Cornell]

just dont fill the tank :rofl:

wether 6.9 or 6.5 425hp out of the box would be nice other than all the pollution crap and hopefully not ford twin turbos that many more problems.. oops didnt mean to write 6.5 haha wonder how long a 425hp 6.5 would last :rofl:

I think the Urea system may be similar to the Bluetec system used by Mercedes in Europe. They add a special water mixture to help improve fuel economy.

technology keeps advancing... all the while they inhibit it with power and mpg robbing emission crap. but, take it all off and

Urea is a type of ammonia that is injected into exhaust to cut down on emissions. I know this because the 100mm+ btu furnace systems we build all have urea systems on the exhaust stacks. I don't know exactly how it works but it reduces carbon and NOx emissions by a great amount. I would think it would be simple to bypass this system but even if you didn't it shouldn't affect HP. I would be willing to guarantee it will not be injected into the combustion cycle as it is not combustible and could cause less fuel to burn which would mean more pollution. I am not sure how much it will cost over the counter but I know in our systems it is relatively cheap and a little goes a loooooong way.

If this is the case then to me it seems the urea is a huge step in the right direction. It would be great if we could still tune our trucks and use the urea to cut down the emissions at the same time, or just not use it and not affect the operation of the vehicle.

cleaner air would be nice here in escondido! (not that i help the situation)

Did a quick search and found this brief but informative def. I also found out the Urea was originally discovered in human urine! The nerd name for Urea is Carbamide.

I do not know the displacement, but:

It has piezo injectors, 2 EGR logs, and a normal single Garrett AVNT.

Or at least the one I saw did.
