[Spridgets] Aviation piston engine question - No LBC

[Jim Johnson]

My understanding is that the biggest problem with the Allison power plants
in the Mustang was the lack of a two stage supercharger. The P-38 versions
with the V-1710 Allison had two stage superchargers giving the P-38 a
service ceiling of over FL400 if I recall. This power plant also appeared in
a few of the last P-40s made.

Cheers!!
