Red Admiral, what do you know of the use of a "waste gate" on mechanical superchargers. (not the exhaust gate on a turbo)
I don't see how it would work with the arrangement used on the carburetor fed aircraft engines as the fuel/air muix is inside the supercharger. (I can see it possibly being used on fuel injected engines or a supercharger stage preceding the carburetor)
On the altitude performance SFC issue, ive seen this too (on some V-1710 models as well), and it also seems to get worse above the critical altitude. Perhaps it has to do with the mixture control in these conditions or the decreased compression ratio.
