If you're doing a lot of intentional wave jumping, be sure to start setting aside a repair fund you're going to need it. It's not real good for them and is rough on the supercharger components. These machines are a lot bigger and heavier than their 2-stroke predecessors and the supercharger is spinning far faster than the engine RPM's it won't like what you're doing to it.
How many hours are on this RXP and has the supercharger actually been rebuilt (not just the washers replaced)? If you're over 100 hrs on the orginal supercharger bearings and shaft and seals then it's well past time for the supercharger to be pulled out and FULLY rebuilt they are considered a "wear item". If the supercharger fails it falls apart INSIDE your engine case and small bearings and broken parts get all inside your engine where they tend to wreak havoc and can destroy the engine... you may not even realize your supercharger has failed initially, the engine may continue running for awhile with just a little loss of power and lower max rpm's, until some piece of the supercharger gets somewhere it shouldn't and breaks something. :-\
