[QUOTE="Nick Sumner, post: 340503, member: 131"] [quote="Hood"] Certainly no British engine manufacturer seems to have escape some kind of technical woe with their high-powered designs. [/quote] No engine manufacturer anywhere working on high powered designs in this era got a new engine to an acceptable level of development without a long hard struggle. The Americans cancelled all their 'hyper' engines, the German engine builders had to be wrangled by Speer to get them back on topic because of their tendency for engineering digressions of questionable utility (hence the great engine project cull of late 1942), but the Japanese were the worst at junking engine designs that didn't co-operate even though each manufacturer stuck with a narrow range of cylinder sizes. The Peregrine was cancelled because the Merlin had more development potential and Rolls Royce were at full stretch, otherwise it was 'coming along nicely'.
