My limiter was set to 6800 originally but due to the intake air temps getting way too hot we rolled the rpm limit back to 6400. There is some variation with pulleys but generally speaking, the blower is running more than 3 times the engine rpm. For very short bursts those rpms may be okay but sustained periods above 5700 rpm is going to generate more heat than the supercharger cooling system can possibly remove.
