I've been taking a look at
this engine made in Italy. It quotes some remarkable performance figures, but when you read the small print the tests were done at 2°C, 1048mb - or in other words somewhere in Italy there must be a dynamometer in a pressurised fridge.
Does anybody know of a reasonably reliable method to adjust IC engine performance figures like this to ISA/Sea-Level conditions so that I can try and reduce this to something meaningful (not to mention comparable with other engines that I know the behaviour of in a given aeroplane)?
