And, still off topic, comparing a Cummins engine to a Dmax, the Cummins has greater torque rise, which seat of the pants, "feels" like more torque, since the V engine has to spin up to keep up and the big C hunkers down and pulls.
Really? Why is that?
My LBZ puts out 650 ft/lbs of torque. The same year Cummins puts out 610 ft/lbs. (so much for the Long stroke BS) My truck puts out 360 HP. The same year Cummins puts out 310 HP.
Who's truck is going to climb the hill faster or tow better? Towing just got easier. :B
Now lets look at torque charts.
Now the LBZ looses what? (hard to tell because the chart is so course) maybe 50 ft/lbs from 1,500 to 3,200 (peak HP) So at peak HP the DM is at 600 ft/lbs or close to it.
I can't find a torque chart for the Cummins for the 2006 year. Cummins in these years are notorious for having pool table flat torque curves so lets just say this is the case the Cummins looses no torque from 1,500 RPM to 3,000 RPM (max HP for the Cummins) It started out at only 610 torque and the DM started out at the same the same RPM but made 650. So the DM made 40 ft/lbs of torque more than the Cummins at the same RPM. (oops I guess the DM makes peak torque at 1,600 not 1,500. So 100 RPM more. (Big woop :R)
BUT.......the DM makes a few more HP than the at 3,000 grand and the DM makes 50 more HP than the Cummins at 200 RPM more.
So much for the long stroke dominating the torque game.
Now if you want to win the efficiency game the long stroke game is the way to go for sure. The engineering videos I have supplied show why this is so. It has to do with heat loss or lack there of for the long stroke engines. And efficiency is big in this time.
You're still trying too hard here...lol. FWIW, my LB7 stock or similar tune would smoke my 2007 5.9 in a drag race and pulled just fine.
Your blathering about which one had more power in stock form is just too funny. Who cares? Either mfg could have tuned them up or down to whatever they wanted (within reason) on all stock components. And one would have more power than the other until one finally cut loose or couldn't pull enough fuel or push enough air.
Why the I6 has greater torque rise? Efficiency of that design I spose.
