...to meander back to the original posting, "yes," both Super Charging (SC) and Turbo Charging (TC) can and do increase fuel economy, but the combination of BOTH can do even better job (hence, my R3350-42 example above).

...SC both MAKES usable power and TAKES usable power, while TC MAKES usable power from the "waste" exhaust heat and gas flow, hence the "title" Power Recovery Turbine (PRT) on the R3350-42 engines.

...both SC and TC have their own pros & cons.
