Pumpgrenze, Stopfgrenze (preferably no literal translations)

General context:
superchargers for gasoline engines

Specific context:
>>Die strömungstechnische Optimierung gleicht einer Gratwanderung zwischen der sogenannten Pumpgrenze und der Stopfgrenze. Die Pumpgrenze ist erreicht, wenn der Verdichter nicht mehr funktioniert, weil es in einem bestimmten Drehzahlbereich zum Strömungsabriss kommt. Die Stopfgrenze beschreibt das Phänomen, dass der Motor eigentlich mehr Luft aufnehmen könnte, die Durchsatzleistung des Verdichters dafür aber nicht ausreicht.
