Turbo or supercharge and NA gas engine
Fellow gearheads good morning, had a discussion with a coworker about turbo charging or supercharging an GM 6.0, Ford 6.2 or Ram 6.4. This is not a you need a diesel or buy a diesel question. Just you...

Big difference between Ford building a turbo engine from the ground up with extensive testing
vs
Bolt a turbo on an hope for the best.
At modest boost pressures is will likely be OK but will never be as good as one designed from the start for forced induction.
Outside of dragsters and certain other racing applications, no one uses superchargers. The main advantage is instant power. While a turbo is spooling up the supercharger is already pumping air into the system. The downside is it eats up some of the power to run the supercharger.
With a towing application, the turbo lag really isn't a big issue as no one expects to do a 4sec 0-60 pulling a 30' trailer.
The big advantage of a turbo is it gives you the power when you need it (at the cost of additional fuel consumption) but when you don't need it, you get the better efficiency of a NA engine. If you stick with the V8, you don't gain any efficiency advantage.
Ford did it by downsizing the engine. Under light load, a NA V6 is more than enough power to maintain highway speeds, so you get efficiency when just running around town but if you need hard acceleration or occasional towing, you have the available power. Since the CAFE rules don't include towing, they didn't take a hit pumping a lot of fuel into the engine while towing.
