Want to supercharge your Norton twin? Here's an interesting project and period piece for someone. Drouin Mfg. of Massachusetts made this kit in the early seventies for the Commando and later Harley and Honda 750. Reputed to give 90 hp, I suspect the engine internals suffered. Here's a website devoted to the kit.
Drouin wasn't the only source for supercharging, Alf Hagon's setup below.

MM might be "Motorcycle Mechanics" magazine. D.
ReplyDeleteThe magazine's spec sheet refers not to the Drouin but to Alf Hagen's earlier, very different blower. Tsk!
