Gm+c 360 Hp 660 Tq ?

[EErmert]

Has anyone seen or read about the DuraMux diesel going to this HP and TORQ? 360/660 Oo.

A friend of mine is ordering a D-max that is 6 months out, something new and improved he said as in higher hp.

 

[JonathanBurk]

Yes, those are the new 2006. 5 Duramax specs. I have nothing bad to say about it, but I'll still take my CTD.

Advertized horsepower has little meaning; none of our (STOCK) trucks puts out near what they advertize. Dyno comparisons on the SAME dyno would REALLY be interesting...

Not sure if the 360/650 combo is available right now, BUT I did drive a 6-speed automatice D-crap the other day. Dad got one for a work truck, the transmission was sweet and the redline was 4800 RPM and the tach goes to 5000 RPM. The transmission goes like this:



P R N D M 1 (in M you shift manually) The shifter is huge and has a + - clicker on it to shift up (+) or down (-). The gears come up 1 2 3 4 5 6 in the odometer screen when in gear M.



-I thought it hauled butt and shifts were quick. It was also quiter than the LY motor. Had the '04 idling right next to the '06, it's a bit quiter.

4800 Rpm??? Wow

I'm starting to get irritated how Ford started the trend of high-revving diesels. Now GM with 4800? Diesels aren't supposed to rev that fast. It doesn't matter if they stay together, they start blowing through fuel and the trad-off of this higher revving engine is a higher torque band. It's amazing that people I know with the new GM's and Ford's actually get less fuel economy than big blocks. I wouldn't stand for that. The reason why I'm concerned with this is Dodge will always follow suit because after all, people go by there seat-o-pants feel when they test drive and will assume the Dodge is down on power because it doesn't run like a gas motor.



Dodge has been slowly raising the RPM of these engines. I really don't see this as a good thing for those of us that pull heavy.



A guy (named Guy actually) I go to the dunes with has a Duramax. He pulls a trailer admittedly a few thousand pounds heavier (mine is about 12k lbs and his is about 15k) and he is the first to joke around that he has seen 4MPG!!!! pulling to the sand dunes. My Powerstroke friend gets about 9mpg pulling this same trip (his trailer is about 1k heavier than mine). I will get 14MPG on this same trip with my 2nd gen. We all fill up together, and we all see the mileage we get. BTW, the Duramax guy has a short bed so he has a 25 gallon tank!



The powerstroke friend of mine just got the new Ford with the Tow Boss package. It has 4. 30 gears and he's impressed with that. I keep to myself, but think, "well, that's because you have to rev past 2k to get any power so you need the lower gears". This is his third powerstroke in the past few years...

If you look at the Cummins Marine side, the QSB5. 9, same block that is in our trucks turns out 425HP and 908TQ!!! They tune it down to put it in a Dodge.

Sorry to jump thread here, But the mention of the Marine QSB made me thing of something



Rumor has it that the Rail relief valve on the QSB is one that is designed for continuous use and will not weaken like our valves, has anyone heard the same rumor?

 

[nickleinonen]

redline was 4800 RPM and the tach goes to 5000 RPM.

that 4800 redline is for when the grade braking is active. the older dmax engines would rev to the same level when the slushbox downshifted, but it doesn't fuel above ±3500rpm just like our engines. the older ones had a dotted red mark from 3500 to 4800 but customers were complaining about the engine over reving when the grade braking happened, but the engine was designed to handle that 4800 with no load from fueling. . so they removed the dotted red section to make customers happy. .

One thing though with Marine engines is they have a unlimited amount of cool water to keep the engine cool (from the lake/ocean)

That is true but they are still cooled with coolant using a closed cooling system just like truck engines, just using a water to water heat exchanger. The big advantage is the air to water intercooler, the intake charge is super cooled as the water cooling is way more efficient than air to air in a truck and depending on where you are can be as cool at 40 degrees.

I recently got a 6. 2L '82 Blazer from a NW Bomber which really raps out if I get on it. It has a tach and will hit 4600 if I don't get out of it quick enough. It would go higher if I didn't let off of it but I'm not about to find out how high. Engine is very smooth up there though, it puts my Cummins to shame in the NVH department. It was rebuilt about 92k ago & balanced, runs pretty danged good but the CTD will smoke it even though it's got the Banks Stinger kit.
