I was thinking last night, why doesn't any company make a supercharger, either a bolt-on or an integral, for an engine. If anyone can do it, you can. Why not try a turbocharger?
Modelers can make more power using the engines they already have, and not sacrifice space or weight.
One condition, though. If you come up with one, can you please send me one free

. Anyway, good luck with whatever you develop.
