A large displacement turbocharged gas engine would need a HUGE cooling system to keep it cool in a towing application. Especially one that has a closed deck block like the 7.3L. The radiator would probably need to be the size of a medium-duty Peterbilt.

I'm sure 4x will be by shortly to refute it with some home-made bsfc to kilojoules of heat loss chart....LOL

I agree with 12V it’s gotta be a deezul if it’s going to tow. Maybe we gotta shrink the cooling system. 60% of our fuel’s energy is lost to heat either out the exhaust or into the cooling system. What if we could run some sort of super hot highly pressurized coolant through a nozzle that would spin a turbine coupled to a generator that could recapture that energy and feed it to electric motors at the wheels?

Cummins had an engine running on a dyno in their skunk works 30+ years ago testing some different materials concepts. It was complete with no "radiator waste" cooling system. Ceramic pistons, 2 or 3 staged turbochargers....I believe it had a condensing steam turbine system geared to the crankshaft.

I guess fuel is still too cheap to warrant messing around trying to get more power out of the same fuel. Just throw a couple turbos on and feed er a little more coal.
