SPECIAL NOTES: * Pressure and flow performance data was acquired in the Vortech Engineering, Inc. test cell to SAE J1723 standards. To see details on SAE J1723 test procedures, go to http://www.sae.org/prodserv/stds/J1723_199508.htm. Superchargers are not rated for flow or pressure at efficiencies below 60%. ** Horsepower data resulted from engine dyno tests and/or extrapolated from compressor map data. Due to our rating system, horsepower figures are a relative guide and not an absolute maximum. Superchargers exceeding 6PSIG require a Vortech standard bypass valve or a Vortech Maxflow racing bypass valve. Superchargers exceeding 10PSIG require a Vortech Maxflow Mondo or Maxflow racing bypass valve. Cog belt drive systems are recommended for all heavy duty superchargers.
Calculating Impeller Speed (Serpentine Pulley Applications):
Crank Pulley Diameter x 3.45*** x Engine RPM at Shift = Impeller
Speed
Supercharger Pulley Diameter
Calculating Impeller Speed (Cog Pulley Applications): #
of Crank Pulley Teeth x 3.45*** x Engine RPM at Shift = Impeller Speed
# of Cog Supercharger Pulley Teeth
