some fuel to the fire:
the real p38L had a mil power rpm setting of 3000rpm's
the AH p38L will only go to 2700rpm's
the question is...
Is the gauge wrong?
Or is the Lightning underpowered?
"The two Allison V-1710F-30 V-12s had a 5.5 in. bore and 6.0 in stroke, providing a compression ratio of 6.5. These drove Curtiss Electric constant speed props via a 2:1 reduction gear, delivering 1,475 HP military and takeoff ratings at 3,000 RPM, or 1,612 HP maximum rating at 3,000 RPM and 60 in. of manifold pressure. Some later engines are described as delivering up to 1,725 HP WEP rating. The engines required 100 octane or higher rated fuel, and had 13 USG oil capacity. The oil was cooled in two outboard chin core radiators, vented via automatically controlled flaps on either side of the nacelle. Fuel consumption was 0.65 lb/HP./hr at 1,100 HP normal rating, at 2,600 RPM."
The B-33 turbochargers drew air from outboard scoops on the booms, feeding central chin core intercoolers with automatic temperature control, which in turn fed the carbs. The B-33 was redlined at 26,400 RPM and exhausted upward, ejector hoods were not used due the device's intolerance of any significant backpressure.
"Every one of these problems was solved with the introduction of the P-38L."
"Let me repeat this again and again. It can never be emphasized too strongly. It makes up the Gospel Word. The P-38L. Now there was the airplane."
"Nothing, to these pilots, after the hard winter of 1943-44 could be more beautiful than a P-38L outrolling and tailgating a German fighter straight down, following a spin or split-S or whatever gyration a startled, panicked and doomed German might attempt to initiate. You just couldn't get away from the P-38L. Whatever the German could do, the American in the P-38L could do better." (cited from [8] with permission from Arthur W. Heiden).
