Just wondering how fast all y'all push your 6.4 when on the highway unloaded and loaded. Any concerns with running speeds over 80mph unloaded for extended periods of time as long as ur watching ur temps?
Unloaded I average 80 mph running some hills and flat and if I get behind a fast group I can run up to 90 mph for as much as 100 miles at a time. I live in charleston, sc so the trips are pretty flat.
When loaded I don't usually run over 75mph for braking purposes.
Only thing that sometimes worries me is when it's summer an 100 deg out my oil temps unloaded running fast get around 209 and coolant 201 with tranny temps sitting round 180.
I have a ccsb, 3.55 gears, 35 Toyo mt, stock height, 20's, fully deleted and run h&s mild tunes 24/7.
I read on here a guy blowing his motor after towing at 120 mph for 100 and something thousand miles before he blew a rocker arm. I was super impressed. He lived on flat land in Arizona or something and ran at night in the desert.
So...how fast are y'all going and how do you feel about it???
