Admiral, looking through the data (as well as some articles on the P-39/P-63) many of those 2-speed engines you refer to are actually the early 2-stage versions. (lacking intercooler) It is mentioned in the engine description, though only one impeller size is mentioned.
The -45 (F7R) is the same as the -39 (F3R) of the P-40D/E but with the auxiliary supercharger stage, 9.5" impeller listed. (for aux stage?) It apears to be the first (at least in the F series) to use the auxiliary stage. The -47 (not mentioned by you) is similar but of the E series with extention shaft and remote reduction gearing. (XP-39E/XP-76 and XP-63) The -93 was used on the production P-63A.
I'm not sure about the -57 model though, according to the chart it had a 2-speed supercharger with "Birmann impeller" of 10.25" and was used on the F-5A, P-38F, and XF-5D lighning. (the altitude ratings of this engine would indeed seem to corespond to a slingle stage 2-speed engine, though the use on the Lighting would seem odd -except perhaps for testing purposes)
The -97 apears to be a single-stage two-speed model, this time with the larger 10.25" supercharger. It seems to be mislabeled in featuring a turbocharger in the charts. The first of the G series.
The 101 was an F series engine with auxiliary supercharger and carburetor between the stages.
The 109 was another E series engine similar to the -93 but with carb between stages, modified crankshaft, and different supercharger gearing with significantly better high altitude performance.
I think the 111 is a mislabeled turbocharged engine as the altitude performance is far too high and the supercharger (9.5") gearing is fairly low. (though strangely 2 speed figures are given) And since it was the engine of the P-38L.
The 131 is similar to the -97, G series with single stage 2-speed 10.25" supercharger.
The G series sees the introduction of the 10.25" impeller. All of the F series (except for the odd F11R -57) have the 9.5" impeller. It also apears that early 2-stage F models may have a 9.5" impeller for the aux stage as well.
