Engine rpm shouldn't matter. The primary would be turning at approximately 9000 rpm. The secondary clutch shouldn't be affected by the higher rpms the engine turns. Or am i thinking about this wrong? Ive run traditional cat clutches at 9200 for years on a modded 440 sno pro for years and never had any clutch failures. Although i realize the power difference between that and a 4 stroke turbo are huge. I wonder if its the torque thats the problem instead of the rpm?
