I was reading something and I thought ......Phoenix?

What is the most "Sustained HP" you can have with any of the big three Diesels, pulling 20k? I mean, up/down hill, hot/cold in whatever conditions can ya swing HP?

I mean, how well can you build a motor and system to be almost stupid proof? I know plenty of folks with DC's, GM's and Fords that push them REALLY hard and don't have jack for gauges...and don't care. These guys run them as hard as possible and don't seem to have many problems?

The cooling system is what keeps most from using crazy high hp constantly. Egt's can be controlled with twins. On the Dodge that is usually in the low to mid 400hp range on the stock cooling system.

The last I towed with twins, I was near 600 HP, racing everything on the hill to the top, and water temp was not an issue, normal, in fact.
You are right EGT was almost totally controlled with the twins, but I did have to back off just a hair nearing the top. A good mile, maybe more, very steep.

Maybe I was only using 400 of the 600 available.

Same here. I've towed 10k with all the boxes on kill on my old twined truck. I know it was using nearly all of it when some unlucky duramax tried to cut me off. I don't think he realized a truck pulling a camper could accelerate up a hill that fast. I'm guessing we played for 2-3 minutes.

I know that it took 311rwhp to tow at 17,000lb combined up on the I 40 going uphill into Flagstaff (7000'?) at 80 mph. So it should take at least 34,000 lbs to need 600HP while towing up a very steep grade at high altitude at more than the speed limit.
