When did the 1300-1350 hp Wright Cyclone begin production? When did they begin installing them in Wildcats?
i think the production of FM-2 started in the fall of '43
p.s. i find that delivery started in September so production wold be started in late summer
I think they mostly went into FM2 Wildcats, the late model "wilder Wildcat" that GM builtI didn't know there was such an engine. Were the higher horsepower engines installed in B-17s?

The R-1820-97 used in the B-17 utilized a Turbo-Supercharger(Turbocharger in modern parlance) which feed a mechanical Supercharger, making it a hybrid Two Stage system. This same set-up was utilized by every Turbo-Supercharged aircraft fielded by the U.S. during the war.The FM2 engines were single stage two speed engines, that were optimized for low altitude performance. The B-17 used turbo-supercharged engines, IIRC, and were quite different in their implementation.
B-17G R-1820 engines had a war-emergency rating of 1380 HP which is in the same class as the engine installed in FM-2s, although the design was different. After the war R-1820s were produced with ratings up to 1525 HP.When did the 1300-1350 hp Wright Cyclone begin production? When did they begin installing them in Wildcats?

Was the 1350 HP rated on 100/130 octane? We're they ever evaluated on 150
