Tests conducted in altitude chamber of dynamometer laboratory of Bur. of Standards. Engine was tested under full power run at ground altitude at speeds from 1200 to 2000 r.p.m. and at speeds at 1600 and 1700 r.p.m. at full throttle from ground altitude to 25,000 ft. in steps of 5000 ft. Propeller-load runs and friction-horsepower runs were also examined.
