Howdy, Cap'n. I saw a few threads on the Shindiawa mills, but couldn't find much else. I'm not talking about a supercharging effect, though... I mean an honest- to- god- bolt- on- to- an- existing- engine belt driven supercharger that will move a given volume of air for each rotation, as well as compress the charge (something I failed to mention in my post). I can't say for sure, but I don't anticipate any carb modifications, because if it works like a draw through setup on a car, carburetion shouldn't be affected.
Gee, I may have to build another plane to test it out on.
