Curtiss V-1570 Conqueror

The Engine Specifications
The Curtiss V-1570 Conqueror was designed as the replacement for Curtiss' successful D-12 of 1922.  The Conqueror went into production in 1926 producing 575 hp and was producing 650 hp by 1931.

Although the Conqueror accounted for 2/3 of the Army's purchases of of large engines as late as 1932, the Conqueror marked the beginning of the end for Curtiss aircraft engines.  Tests in 1931 showed glycol leaks and, with a declining interest in liquid-cooling, funding was cut a year later.
