I was hoping that you know the answer to a specific question:
How much of engine power was used by the turbocharger on the P-47 (for example)?
Alas.
There is a chart somewhere, that I KNOW you've seen, which shows the power coming out of a boosted aviation engine in terms of percent of power in gasoline that gets used for what purpose. Can't seem to find it just now, but I have it somewhere. We've ALL likely seen it at some point. Seems like it had typical percent of the power in the gasoline allocated to various things, including engine power, power loss due to friction, power loss due to supercharging (or turbocharging? ...maybe not), power loss to exhaust (I seem to recall it is a decently high percentage, as we'd expect). I'll look around for it and try to re-discover the graphic. I THINK it came from Rolls-Royce, but I may misremember that.
Found it at: Waste Heat Utilization
Good article.
