Even with its hybrid settings -
From the Tiffy performance thread -
"Comparing the engine chart to the November 1943/July 1944 settings, I'd suspect that the +11 lbs/sqin settings were reserved for the V-1 chasers, at least at first. From Clostermann's books, I'd conclude that 150 grade fuel was made available to fighter units in Europe, too, but I haven't gone back to check the date. (He was flying Tempest not Typhoon, but still ...)"
i.e. 11lbs boost 1st use Nov 1943.
As for the 4 bladed prop -
Granted fitted in 1944, BUT this did little more than decrease the takeoff run by approx 150ft when loaded with external stores.
You are correct though, its another hybrid that will hopefully be sorted out when its turn comes for a remodel.
