Well my CumminGs makes 2 billion lb tq at 1600rpm and gets 36.654mpg towing. Lets see the Duramax do that..oh yeah all on the stock 47re.

Seriously though. I do not own a diesel yet. I am looking to get a 3rd Gen. But there are other trucks out there. I think people are getting way to caught up on the Cummins is the best. Yes Cummins does have great reputation and have been proven. They are put in trucks that people buy and use hard. Dont get me wrong I am getting one but you gotta admit those Chevy's are making their place in Diesel World. Give them as much time on the seen as a Cummins has had and see where there standing. Im one of the ones who see the smoke rolling and im interseted. I love power and black smoke and it dont matter if it's a Cummins, Duramax, or Powerstroke were all in it together.

 

we can be technical yes, but look up the statistics on a diesel engine. there are three classes 2,000-3,000-4,000 rpm. look them up you'll find it. And a v-8 platform is never finely balanced neither, it takes much more effort to produce torque in your configuration. And torque is what a diesel engine runs on, HP is for higher rpm engines like gas that get their power from the hp they produce at the top of the rpm scale. I will guarantee you that you will never be able to push 710 lbs of torque at 300 hp, that is because ( it is not efficient ). And I never said that it wasnt a great engine, I just stated the facts. But, it is true we all just love to outrun those little sportscars.

 

Please show me the book that classifies diesel into 2K, 3K, 4K rpm. The real classifications are
Low speed: 60-120 rpm (very large and used to power ships mostly)
Medium Speed: 300-1200 rpm (mostly stationary power units, gensets etc.)
High speed: 1200 rpm + (automotive, equipment)

 

There are auto classifications

 

hdmax, Evan's LBZ is an automatic, only tranny you can get, i wasnt talking about his six speed LB7 truck, he has alot of stuff done to it, he put a tranny in the LBZ and it dynoed 512, and the only thing my friend Robs truck has is 5 inch exhaust with a muffler and the tune, it must be doing pretty good, he took 5th at Glenford last weekend, 12th at wilmington and 5th at Xenia a couple weeks ago, we will be pulling at Lebanon if you would like to come watch, and Robs truck is on a stock tranny and he drives it every day, has 20K+. i didnt say the tranny was going to live forever, we plan on putting a tranny in it once the stock one goes south.

 

I saw several trucks that had dyno'd more torque with the same hp as what you stated, 7.3 PSD's, dmaxs and CTD's too. I was told by the dyno operator that my 12 Valve put down 325/850. How's that for inefficient and not being able to do it?

 

You are pitching a fit about your 12 valve, thats what I drive buddy. And my truck has more aggressive mods than yours. My dyno pull was also on a mustang dyno but they are not as accurate as others out there. And I also said a V-8 platform, not an i6, so what are you defending?

 

I love an inline 6 diesel myself, and the cummins has proven itself to me. The duramax has proven to be a pretty good motor though, and definately competitive so far. I just like the cummins/I-6 configuration, so that is my choice. I am not a big fan of a V-8 diesel, but if we all didnt think different, then what fun would that be? Im happy for anyone who likes their D-Max. i just have a different preference

 

Dang another my engine is better argument? They are fun though... I bet most people on the other forums see us as ignorant hard heads who are lost in our own little world because we don't consider any other diesel up to par with the Cummins.

 

Yeah, were all smoke addicts that just cant get enough!

 

What class in the D-Max and Powerstroke in? I know the Cummins is a Medium Duty Diesel engine.

 

Forgot to add. Drove neighbors D-Max and liked it. Strong and spunky. Had an 95 reg cab Powerstroke a few years ago. Good motor and last to 325,000 miles. Only thid is the fule consumption was to to great. That's why I went to the Cummins motor. Got a Cummins in my CaseIH and very good on fuel and neve had one problem yet. I like my 06 because it can pull my 40' stck trailer like a train and great pmg to boot. My Ford had a little troulbe pulling that same trailer fully loaded. But once up to speed it was good to go. Neighbors pulls a 43' live-in horse hualer. He can pull flat ground great but he hills slow it up quite a bit. I just don't like the 6.0 or the 6.4. They're junk IMO. Very interesting thread indeed.

 

agree about the 6.0 and 6.4, and I will say that the 7.3 is a good motor. I think ford should still be running it today, I have just had such good luck with the three cummins I have owned to change yet. Ill admit they are sluggish stock, but once you wake em up they can be very strong and very reliable engines.

 

7.3 was good. It wouldn't be able to compete with the high standards people have today. In 1994, Dodge revolutionized the pickup market by introducing a full size medium duty Cummins engine in their light duty trucks. That blew the competition away and until just recently no other manufacturer could make an engine that was as good in a light duty. Diesel engines have come a long way in just the past couple decades. Now the Duramax is trying to compete with the Cummins. Can't blame people for believing Cummins rules all.

 

Here's the reason I'm not driving a Duramax in either a Chevy or GMC right now:

1) Independent Front Suspension - I still don't trust them on a 4wd. I know I know - that's probably an antiquated opinion, but I still really like the solid axles

2) Cost - I got my Dodge for about $3500K cheaper than a Dmax

3) They're UGLY - the 07's are the worst. I probably could've stomached an 04 thru 06, but no way no how now...
