    Anyone have this setup? 2014 KW T680 Paccar 400hp with Eaton Fuller 10sp and 3.36 rears. 22.5 tires or about 84 inch diameter. I'm looking to roll at about 65mph between FL and TX. Thanks

    Assuming you're running 11R22.5 tires (41.36" diameter) and 0.74 tenth gear, you'll hit 65 MPH in between 1300 and 1350.

    Trying to create the ultimate fuel sipping flatlander special. May as well go with the dummy drive axle like MVT runs.

    If you want any sort of performance, as when trying to outrun tornadoes and ice storms, (yes, they get them on 10th street also), go with a 450HP and a 13 speed. Better resale too.
