No turbocharger is mentioned, even for high-altitude work. The Napier Nomad gave the best mileage in the 50s, and was more like a turbo jet with the peak temperatures moderated by using pistons for the initial expansion.
Cylinders that are not in use still create friction with this setup. I don't think anybody liked that 4-6-8 Cadillac option.
