Well, Scottsdale to Flagstaff.....150-160 miles. 1300 ft. to 6300'? What's the grade.....2%?
I just watched a test of the ecoboost with a 10k trailer running the Eisenhower tunnel... it stayed floored and spinning up there with a normally aspirated gas engine, so....find a real hill.
And, now why is it that that beast ecoboost isn't pulling the big loads in the HD trucks? Self destruction??
I travel with my trailer up and down the mountain to my my vacation home; 4000' to 9000' in 16 miles. You should put the ecoboost on something like that and see if it runs 1800 rpm...it won't - but send us a pic.
Just messing with you. You seem to be very enamored of the ecoboost; and it is, from accounts by owners that have spent the money for it, a powerful engine (for a 3.5L gas)....enhanced on "steroids" to act like a "real" towing motor. I think if you love it, go for it, but don't be misled thinking you have a real HD towing truck...you don't.
Edit: another way for anyone to know it's not an HD towing truck is you're running 49.8 lbs psi, with a 9k trailer. I'm assuming P rated tires??
Edit; here is a post from another forum on the grade of the route;
"This elevation change of about a mile in height over 125 miles in length works out to slightly less than a 1% grade on average the whole way.
