Every body thinks that super charger increase the efficiency of the engine which is a wrong concept.The super charge increase the power to weight ratio but not the efficiency. The turbo super charger pumps more air (oxygen) into the cylinder so that more fuel can be burnt in the cylinder which increase the power so the same engine can develop more power by using the turbo charge compared to with out super charge, hence power to weight ration increase but not the efficiency
