Get rid of the pcv valve. You’re pressurizing the crankcase with it. Cap the hole in the throttle body and vent the valve cover with a catch can with as big of a hose that will fit (-10 minimum).

I don't totally agree. On a race car that would be OK, but not really on a street car. I don't have experience with a "supercharger", but I do have with turbos on the street. With any street car you need some way of ventilating the crankcase. Is the engine under boost any time it is running? If not the engine needs some ventilation when not on boost.
PS: the PCV valve will not pressurize the crankcase. When the intake goes positive pressure the PCV valve closes.
