HP required to pull hills
Here is a formula that will give a rough idea of the flywheel HP required to tow a fifth wheel up a grade at speed. HP= s(53000+gw)/31800 s = speed (mph) g= % grade w= weight of truck and trai...

I would say it is pretty accurate. My complete setup is 14,200 scaled. My truck is 300hp stock. I have a few small things done to it and it dynoed 292 at the rear wheels when I had it tuned. I like doing that to my LS powered stuff.
Makes 292 at 4400 rpms to 5200. I don't worry about running the LS stuff to 4500-5000 RPM. Just what they do, although I can't remember the last time I hit 4500.
It said I needed to 287 HP to go 60 up a 7 percent grade. It would probably do it. I usually keep it at around 50 on anything that big. On something like Vantage in Wa state it will cruise right up it going 60 at 3800 to 4200 rpm.
