And that is the fundamental difference between the Cummins and the v8s. They want the horsepower because they will pull loads faster and people look at the numbers and go ooooh aaaah! GM and Ford build diesel engines like they are gassers.

Cummins has always had a mindset closer to the heavy Duty trucks. They have always emphasized low end torque and low RPM.

It seems to me, that Dodge has always been more of a work truck than the other 2. Not so much in the fact that they work harder or better, but in DCs options that they offered for their trucks. I.E their interiors were always cheaper than the other 2. Even their "top grade" trim packages weren't even close to The Ford or the Chevy's. The trucks have always been lower priced also.

Though I noticed that changing these last few years.

 

i am still waiting for the fiat logo to show it's face....

 

the fiat logo isn't going to show its face. But either way they'll still have a deal with Cummins.

 

Why is bigger internal parts still mentioned besides the fact that there are far less moving parts? Well: at the present time where mega combustion explosions, combined with trucks pulling Big semi trailers on occasion, and too much alcohol..hehe, strongest thickest internal parts are the difference between moving it or" what the hell was that sound?" ah crap i think it came from under the hood. Let's face it most of the trucks coming off the assembly line get intake, exhaust, boxes, injectors...etc and before you know it you are pushing 600hp 800 tq or more[transmission well that's another issue]. So my point SIX THICK better then 8 thin!

 

Im proud of Dodge and Cummins for saying, screw you and your horsepower. Whats next? 600HP? there is no reasonforthe trucks tohave what they havenow. Did any of you think about how car insurance works? some of the considerations are vehicle weight because of the damage it can do, the value incase it needs to be repaired, and the horsepower, not torque because horsepower determines top speed. I know some of you will think thats torque but its not. That is why an S2000 can go as fast as a mercadies with a supercharges V6. Registration costs are also effected by power. More power means more fuel is used and they rase your taxable amounts. This is why my truck is 500 a year to register as compared to the 700 of a truck only 3 years newer but with 100hp more. It also weighs about 1000 lbs more, but its true. again, I am proud of Dodge for not going with the fad. Ford has a great advertising team but as of 2003 ford has lost sales every year and as each new year comes, more people are buying and repairing older dodges, because they last. Some things are more important then sheer power. How much power do you really need togo 70mph with a trailer? dont forget how much a speeding ticket costs when towing and insurance costs are added. My 2002 SO willtow a trailer with a car at 80mph to vegas no problem, ive done it. It was awsome. Igot to take a tuned racce ready Viper to LVMS. A cummins ISC only has about 280hp adn around 1000 ft lbs, so why build a smaller engine with less torque when you have a bigger engine that will do the same

 

You know there is still the rumor that keeps surfacing up! It went from 7l to now an 8l Hino 1ton Toyota! Thats a Monster! I hope they don't do it, I live with to many Toyota fans that want to rub it in my face! Oh BTW if you put a 1999 5.9l Cummins next to a 7.3l of the same year no modifications rear wheel drive, M/T. The 7.3l will out tow (Reason more cubic inches and 2 extra cylinders)!
The next series of Dodges will get the Urea. They are not totally walking away, and as far as that regenration and the SCR processing. A simple tune cold fix all of that, you don't even have to remove the equipment.

 

Normal combustion is a controlled burn. If you have "mega combustion explosions" that is called detonation and that tears stuff up. No matter how thick your rods are.


That is because Toyota built a concept truck with a 8l Hino diesel in it. However, to make the engine fit they had to remove all the climate controls and radio. It will never be more than a concept truck.


If you put an 02 [7.3 vs a 02 5.9 they both tow about the same. Cubic inches and the number of cylinders hasn't changed. They just increased the fueling, compression and boost.

Edit: These dyno graphs would suggest a 99 Cummins 4wd will out tow a 202 7.3 2wd

Though to be fair, this graph has the PSD clearly tromping the Cummins.

As the saying goes, There is no replacement for Displacement, Except for Forced Induction!


It will be interesting to see what the Cummins can do now that they have stroker crankshafts for it and are starting to come up with some decent cylinder heads.

 

Reminds me of some of youtube "geniuses". Had one guy tellin me that chips and programmers were completely pointless, they did not increase power, and only made the truck smoke more with no increase in power, and the only way to burn more fuel was to increase the cylinder size

Lots of fun days commenting with people on youtube

 

Incorrect. Horsepower is nothing but math, its not an actual unit of measurement. HP is torque over time, thats why an engine always has equal HP and TQ at 5252rpm and always has less TQ than HP above that.
Torque is actual power. An S2000 can keep up with a supercharged V6 because it has a whole bunch of power strokes per second instead of lots of torque. Thats why everybody makes fun of how wimpy its engine is below 6000rpm.

Not quite. The value and weight of your vehicle are considerably less, thats why its cheaper.

 

ha ha im guessing that the world has been wrong since around the 1700's using horsepower as a mesaurment. yes you preform math to achive the hp number but the same can be said for torque.

as far as this horsepower war thing goes its good but i see more problems with factory high hp trucks and the general public. For what i do on a daily basis i would prefer a truck with high factory torque for pulling.
