As a non-engine freak, can I ask a rapid question?
"What's the difference between a supercharger and a turbocharger?"
As I understand it, a "supercharger" is a compressor driven from an auxiliary gearbox on the engine shaft, while a "turbocharger" or "turbosupercharger" is a compressor driven from a turbine in the engine exhaust, both feeding the compresed air back into the engine inlet manifold.
Right or wrong?
