ENGINE OPERATING PARAMETERS (Continued)
Manifold Pressure. Intake manifold pressure rise above atmospheric after the turbosupercharger
with boost to 0 inches Hg (mercury) atmospheric pressure, should not exceed 35 inches Hg;
without boost, 28 to 32 inches Hg. Variation between left and right banks should not exceed 4
Oil Consumption. Engine should not consume more than 0.0075 pounds per brake horsepower
hour (lbs/bhp/hr) of lubricating oil when operating under full load and using engine oil
conforming to Military Specification MIL-L-45199 Grade 2 (OE 30) (item 21, WP 0173).
Oil Pressure. Engine oil pressure should not be more than 70 psi or less than 40 psi when engine
is operating at 2400 rpm. The engine oil pressure should not be less than 15 psi when engine is
idling at 700 rpm, measured at or adjacent to the oil pressure sending unit, with oil temperature of
140 to 250 F (60 to 121 C), using engine oil conforming to Military Specification MIL-L-45199
Grade 2 (OE 30).
Speed Range. The engine must operate satisfactorily under all loads through a speed range of
1000 to 2400 rpm and must idle satisfactorily at 675 to 725 rpm.
Temperatures. Induction air inlet temperature should be 85 10 F (29 -5 C).
When operating at full throttle under full load on a dynamometer at 1800 rpm, the engine should
not consume more than 0.400 lbs/bhp/hr of fuel conforming to Specification VV-F-800 (DF-2).
