Time to do my share to improve the S/N ratio here at r.a.m,
or at least make a try at it!

It's easy to overlook. No exhaust pipes visible protruding
from the sheet metal around the Allison engines on the P-38.

Given that Lookheed, and Kelly Johnson in particular, paid
a lot of detailed attention in the design and execution of
the aircraft, I'm wondering why they never made an effort
to use exhaust thrust to squeeze a few extra hp/mph out of
the engines for this aircraft.


They did, by having the exhaust drive a turbocharger.
