Greg,

Superchargers are sometimes simpler to implement, but there are other reasons they aren't as popular on aircraft. First they are a power robbing device. There is a net gain in power of course, but the charger can require 10-15 HP to drive it at WOT and it makes the engine less efficient. The other problem is you must be sure the unit is up to continous use in the boost RPM range. Lastly the mount must be solid enough to hold up to continous use as well.
