Today's 12 volt superchargers will make that boost number easily on the basic 4 cylinder vehicle's modern charging system. It takes POWER to spin a compressor wheel or rotor, be it belt driven, electric driven, or exhaust driven.
A very basic calculation which I can post up if anyone is interested. The same basic calculation could be used to determine the hp George is consuming with his Roots supercharger.
