The Tempest II had been intended to be powered by the 2,250hp Sabre Mk IVA in-line liquid cooled engine. Sir Sydney Camm however felt that the radial engined Tempest Mk II would offer the ultimate in performance for the Typhoon/Tempest line and, as a result, considerable effort was made to improve the efficiency of the 2,210 hp Centaurus air cooled radial engine.
The RAF technicians, studying a captured Fw 190, found that the Germans had solved the problem of cooling a closely cowled radial engine. They used an annular oil cooler which was built into the leading edge of the cowling and cooled by an engine driven fan. The engine exhaust system avoided the use of a collector ring and gases were dis- charged through individual exhaust pipes mounted in front of exit louvres on each side of the fuselage.
