Then I also have the Racing Beat Alternator Pulley which is suppose to reduce the alternator rpm by 20% . So with both my alternator is running approx 40% less rpm than stock. Still provides plenty of power for all my crucial systems as well as two landing lights, strobe light, Nav lights, pitot tube heater and charges two Batteries. I am hoping that by derating the alternator such that it will last longer. Ed Anderson
