Power Settings
Max RPM 2350 RPM (5 minutes max)
Max continuous RPM 2250 RPM
Idle RPM 550 RPM
Max MAP ambient pressure + 85mm (+3.4”) hg
Max MAP (1 hour) ambient pressure + 80mm (+3.1”) hg
Max continuous MAP 710mm hg (28” hg)
(Rated or METO power is 2250 RPM with a MAP of ambient pressure + 80mm for 1 hour after which power must be reduced for 5 minutes.)

(Note: the engine oil inlet temperatures are below those recommeneded by manufacturers of modern aircraft engine oils and probably represent limitations of the lubricating oils available to the Chinese when the Huosai engine was designed in the 1950's.)
