[QUOTE="Garbage_Mechanic, post: 1544663, member: 1610"] BMC it was a full F550 drivetrain. The ZF6 and the S110? didn't break they MELTED. His engine build would make the continuous HP and torque to pull the load but the drivetrain couldn’t get rid of the heat. How big is the drivetrain in a semi with a 450 hp engine? Very common to need a cooler on 10 speed and 18 speed gearboxes now. I recall when big power first started to become available in big rigs. Guys were putting 600 hp KTA Cummins and 3408 Cat V8’s in trucks running over the Grapevine out of LA. Has to go to triple rear axles to keep diffs together. [/QUOTE]
