STATIC FUEL PRESSURE ADJUSTMENT
The
Supercharger Regulator
comes preset from the factory at 40±1 PSI. Unless another setting is desired, this does
not have to be changed.
NOTE:
Maximum static pressure setting for this unit is 60 PSI.
WARNING! DO NOT SET STATIC PRESSURES ABOVE 60 PSI, AS DAMAGE TO THE REGULATOR FUEL SYSTEM
COMPONENTS MIGHT OCCUR.
TUNING THE SYSTEM
The Holley
Supercharger Regulator (SR)
comes with one additional pair of plates that changes the fuel pressure/boost
pressure curve. The
SR
comes with a baseline setup, which contains no plates. The baseline setup will provide a larger
increase in fuel pressure as boost increases. If a lower slope is desired, the additional disks can be installed. The graph
below indicates the increase in fuel pressure as boost increases with and without the plates installed.
