well, it was certainly better than the MC 200, well matched?MC 202 was well matched against a P-38F, G or H
There are not a lot of tests for these middle P-38s however we have two things going on.
Usually US tests generally cut the power after 5 minutes or a bit more while climbing so climb rates at low altitude reflect actual combat capabilities. Climb rates from tests at higher altitudes do not. Allison powered planes were tested at 2600rpm after 5 minutes.
If you were in combat the only thing that prevented you from using 2800-3000rpm for climbing was the engine temp and for the P-38 the carb intake temperature. If you were cruising at 20,000ft the 5 minute time limit disappeared, your 5 minute time limited starts when you open the throttle.
There was quite a bit of dispute about the carb temperature limits on the P-38. Officially it was supposed to be 45 degrees C which severally limited the power on the pre/J versions.
However in testing they were running well into the 50 degree range, in fact Kelsey was running 70 degrees at Lockheed with no apparent problems. In fact he reported the following
""I finally succeeded in reaching limiting carburetor air temperature at altitude. I got excessive roughness, cutting out, and backfires at 190 and 200 degrees F [88 and 93 degrees C]. at about 25,000 feet"… one intercooler was actually blown up"
Kelsey was known to push things.
Some pilots, much like the P-40 pilots, removed/modified the throttle stopped and used much higher boost settings in combat when needed.
"small numbers of MC 205 available by April 1943"
Old book says first operational use (or first allied note) of the type was on July 1943 when escorting torpedo planes attacking naval forces off Pantelleria.
On Sept 8th 1943 the Aeronautica had 66 on strength of which 35 were serviceable. limited production continued after the surrender. Total production was 262 MC 205Vs.
Chances of a P-38 formation engaging MC 205s was rather remote. Many US pilots could finish their tour without ever seeing an MC 205 (or any of the other "05" types)
Yes there were over 4 times as many 202s.
