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.
The engine will only use as much fuel as needed to do the work. Take a look at the TFL video of the Ram TRX (700hp ?) and the Ford Raptor (EcoBoost) on I70 with the same trailers at the same time. The mpg was surprising. It’s only a guess but it wouldn’t surprise me if the programming can be set to protect the engine from a pilot trying to tow 15k at 94mph up a 10mile 8% grade.
