does a car come with a supercharger these days?
no , cause they are not as efficient at making power. A turbo running less boost will make same power as a supercharger setup. Less boost = more safety.
A smaller turbo boosting sooner running same boost as SC kit, will make more power everywhere as long as the SC is centrifugal.
Turbo >>>> SC kits
I´m only biased to the facts.
