Inaccurate performance data for BOB fighters in COD comparing to RL data

[Skoshi Tiger]

Considering those test certificate shown earlier (one issues back in '37) clearly stating that the test engines, even using 87 octane fuel was capable of over 10 1/2 lbs boost at 3000rpm and would give about 200 extra horsepower (at the expence of engine wear and possible failure at some point) at those settings, is there any wonder that in combat situations some of the pilots would try to use it?

Even going so far (before the official modification and the introduction of 100 octane fuel) as modifying their boost cutout controls with match sticks to obtain that extra performance.

I'm sure it was the same for pilots on both sides of the Channel.
