Initial Supercharger Procedures

Initial use of the supercharger procedures:

1.) Manifold flatness: the intake manifold must be flat to the mating of the supercharger bottom. if the manifold is not flat, the supercharger case can become damaged during the tightening of the supercharger to the intake manifold.  this damage will cause a warping of the rotor bores. the warping will cause rotor to rotor contact or rotor to case contact and will also affect rotor to case clearances and cause a loss of boost and blower efficiency.

a.) The correct way to check the flatness of your manifold is with a machinist straight edge and a feeler gauge.  the manifold should not be more that 0.005" from flat.  if the manifold is not flat, it must be surfaced to correct the problem.

b.) Recommended torque of the supercharger to the manifold is 15 ft/lbs

2.) Lubrication: each supercharger is equipped with teflon or nylatron strips. these strips are used to increase the sealing ability of the supercharger. each teflon strip touches the mating rotor on a designated sealing pad. the supercharger is designed to use the engines fuel as a coolant and lubricant. the supercharger rotors should be heavily coated with a lubricating spray (supercharger gel lube) prior to initial engine start-up. this is to protect the rotors for the small amount of time it takes the fuel to arrive to the blower during initial engine firing.

RBS recommends that you follow these procedures after every rebuild/ re-stripping of the blower and before each initial engine startup.
