The fact that the R-1820 was intially introduced in 1933 doesn't mean it was the same engine that powered the Brewster or the FM-2 later for that matter.
So very true... The R-1820s fitted to our S-2s were rated at 1525 hp. Hang one of those on a Brewster and they'd have something to whine about!
R-1820-82WA different engine with wep
