Many people have added the Paxton supercharger to the 226-engined Aeros, but as far as I've been able to tell, it was never an option by the factory. I am sure some were dealer installed. John Parker used tell about his Bermuda that he bought new and he installed a supercharger himself but, for some reason, could not install the fan for proper cooling. He said it ran well but he did not want to get stuck in traffic or climb mountains. There is an F-head automatic '53 Aero Eagle on the west coast with a supercharger that someone created that runs perfectly fine and includes a fan.
