Several of my sources agree, that the only engines the Finnish Buffalo's used were R-1820-G5's which came in with 950hp, not 1100hp. (Same as the B-139.) None of the Finnish Buffalo's were Whirlwinds, only Cyclones. The Finn's after allying with German, were cut off of American parts, and had to due to capturing Russian M62-63 Radial Engines, which were still American Wright R-1820-34 Cyclone copies. There's no mention of Whirlwinds being used in Finnish Buffalo's that I can find in any of my books, or sources on the internet. No American Buffalo's were powered by Whirlwinds either.

I've flown both in 1946, and they're both fairly equal in acceleration. The only engines the Finnish Buffalo's were equipped with, were R-1820-34 and -40s (like their American counter part). Wright Whirlwinds are only like at their best R-975 9 cylinder at 300-450hp. No 1,100 or 1,200 hp.
