My (soon to be) father-in-law said he hooked up a squirrel cage fan to the carb on his inline 6 back in the late 50s or early 60s and he said it made a huge increase in performance. It took a lot of monkeying with the fuel-air mixture because the system basically had to be on all the time. In that sense, I guess it's not a true turbo/supercharger, but instead continuously feeding more, cooler air to the carb.
Are you saying this wouldn't work?
