The 1937 RAF Training Manual has instructions for boost cut out independant of 100 Octane fuel.

Additionally this certificate list the boost pressure well above the rated 6 1/2 lbs without boost cut out. The only approved fuel for this aircraft is 87 Octane.

I hope you guys are aware that the line "Emergency 5 mins.max." is related to "95°C" oil inlet temperature?



This test certificate has a better layout: http://www.spitfireperformance.com/k...ertificate.jpg

The power curve is a simplified form of this graph: http://forum.1cpublishing.eu/attachm...1&d=1337143252
and most certainly only contains calculated values which were derived from certain reference values or were applied shorty under controlled conditions to determine the engine power.
