Drivability blower vs turbos

Your dad has no idea of what he is talking about. Turbos love highway gears. You have to downshift to get rpms up with a supercharger to make boost. A turbo just needs to be loaded. Low rpm drop throttle and will rip the tires off on the street. Just do a little research on U tube. A turbo is the ultimate variable displacement engine. Low boost drives normal and does not use any extra fuel. Superchargers always use extra fuel
