I can't believe the amount of trash talking going on here. Brand X verses brand Y and which part of the country is better.
I think the simple and best way to determine power would be to dyno the trucks at the same time and location and have timed run where you tow 20,000 trailer up a long and steep grade.
I don't believe a sled pull is a viable method of determining who has more power since you have traction and track conditions which factor in as unknown variables.
Just exactly what is so difficult about dyno'ing the truck on the same dyno? I know some people will have to drive a little further to get there, but this should end the discussion about who has the most power.
If you want to use a pulling track to determine power, I'm willing to bet I could beat all of the diesel trucks with my Chevy 350 powered Land Cruiser. Of course my track would involve going over large rocks and boulders. See just how ridiculous this claim sounds????? This is why a sled pull is not a good measuring stick.
