Having ran huffers on a couple of old tech built for towing 454/460 one ton drw trucks in commercial service in the '70s heat was a engine killer.
This is 40+ year newer tech but I would like to see a actual towing test up the IKe and see how the belt driven huffer and other mods deals with excess heat through the engine/tranny. See what actual temps are like working heavy rather than a drag race.

I was wondering the same, was thinking that motor would really heat up from a long hard pull. With that much power it should easily complete a "full pull" with the 15K trailer up the Ike (60 mph the whole way) but could the cooling system exchange that much heat? And it would be fun to snicker at the abysmal mpg.

Idk what all would need to be done with the cooling system (or maybe even internally, larger water jackets, etc) but this isn't 40 years ago and there are already vehicles putting down this much or more power and pickup trucks built to tow that are making just as much heat, so I'd say the cooling system is easily doable.
BUT this truck isn't built to tow. It's not even on the radar as a real tow rig, nor would it likely be anytime in the foreseeable future. But you guys already know that. It must just be the irresistible need for antagonism speaking.
It's a custom hot rod and a cool one at that...that will also tow well.
Any new diesel will still eat this blown 7.3 for lunch, up a hill.

He!!, I remember actually doing an Ike test, on the Ike, with my buddy who had just installed a TRD blower on his 5.7 Tundra. He was bragging about it having 500hp! (which in fairness "was" a big deal 10-15 years ago). Asked how much hp my truck had. It was a LB7 Duramax with just a tuner. Told him a little over 400hp. I was running level 4 which was supposedly a 120hp tune on the 300hp stock engine. I didn't want to scatter the trans on L 5 or 6.
He said his 500hp tundra was going to wax the Chevy. He had a 2 place open sled trailer with 1 sled on it, so maybe 1500lbs total trailer. I had a 3 place enclosed with 2 sleds in it, so maybe 3000lbs total.
We hit it both ways on our trip to ride that day. The long 7% stretch going up Eastbound from Silverthorne to the tunnel and the shorter Westbound steep area at the bottom of the climb Wet of Georgetown.
My 400hp/800ftlb diesel left his 500/500 Tundra like a bad habit up the hill!
And his truck was a TRD with 3.91 gears. I was running 3.73s in the Dirtymax.

It's virtually the same comparison between the blown 7.3 and a new diesel pickup.
