Anyone familiar with the lifespan of a supercharger? I have been running a V3 Vortec and intercooler combination for about 155,000 k and am concerned that the gears might be getting worn, although the car runs great. Gears make a little noise until the oil from the reservoir circulates upwards onto the gears. Although I think is somewhat normal I am thinking about sending it back for a rebuild. Anyone have any thoughts?
