Just to be crystal clear.. this data is for the 87oct?

And of all the graphs listed in the graph, which one should I be using to compare to?

On that note, do you (anyone) have any 100oct test data for the Hurri?

Thanks in advance!

The RAE chart:

is for a 100 octane fueled Hurricane, but the boost is limited to 6.25lb, IOW, no tests were done at the 5min combat rating, but the revised PEC figures resulted in more accurate speeds from prior tests. This test gives data points at 5000 and 10000ft for various levels of boost up to 12lb:

The ability of the Merlin III to give more than 6.25lb boost above 10,000ft is shown in the Spitfire I RAE chart:

, since it also uses 12lb boost, so using these charts should enable you to reconstruct Hurricane performance using 12lb boost, at least in level flight.
as was done here:http://www.wwiiaircraftperformance.o...peed-HRuch.png

and here for climb rate at 12lb boost:
