I don't have the particulars or Bob's design, but he is not using the Bosch design for his dual output CDIs. All I know(or think I know from some correspondence) is that he uses power supplies with a few hundred kHz to keep the size and heat dissipation low while maintaining high rpm capability and power. His CDI designs are nothing like the Bosch CDIs that he rebuilds. Fred

Bob has clearly been playing with this. How are you managing the heat Bob?
