I'll try to clarify one more thing. A turbocharger is barely more efficient than a supercharger. Both are deprovements over a naturally aspirated engine running full power, Otto cycle with blowby losses. The best thing about a turbocharger is that the design lends itself to very high specific power achievable.

I invite you to do the math on a Turbocharger.
On the engine side, 1200 degrees, 30 psi absolute. On the atmospheric side, 300 degrees, and 15 psi absolute.
Assume 2 liter engine, at 3000 rpm.
Calculate the horsepower available in the exhaust.
(Hint. Check your work by comparing to dyno chart of a 2 liter engine at 15 psi boost spinning at 3000 rpm).
