[QUOTE="Bad Company, post: 13691311, member: 141815"] But at the same time you increased your boost at peak Hp at Max Engine RPM with faster supercharger RPM across the complete RPM of the engine. Now you can do the same thing with only changing the upper. WHY??????? Because you can match the blower RPM you achieved with either an upper and lower pulley change. It is strictly about blower RPM and the volume of air exiting the blower at any given RPM. This whole thread is really about moving air into the engine and nothing more than that. [/QUOTE]
