I've heard the parasitic losses of a SuperCharger vs a Turbocharger is a bit more than "small". More like 20-30% to drive them
Why else has the manufacturer stayed with Turbochargers?
Also, a Supercharger will not produce full boost before a turbocharger. They build boost in a linear fashion, so they don't reach full boost by, say, 3000 rpm's, whereas a turbocharger can and maintain that level up to redline. That is my understanding anyway.
