revisit La-5fn engine timer (10min are too long)

[the_emperor]

Currently the La-5fn can run 10min in boosted mode (1200mm/2500rpm) and whooping 20min when throttled back to 1200mm/.2400rpm:

 

most wartime scources and scources after that give a 5min limit für the La-5fn and the Ash M-82fn engine:

1943 La-5fn; 1944 La-5fn; 1945 Tu-2 Ash-82fn;1947 La-9 Ash-82fn; 1947 Ash-82fn; 1950 La-11 Ash-82fn; 1954 Ash-82fn

a) One source (1945) for the La-7 with M-82fn engine stating 10min and

b) one source (1944) for the La-5fn that I dismiss as it looks like it has been tempered with. A 5 converted to a 10.

All compiled here:
