If you look at Banks chart, you will see that Merlin XX is a ~625 hp at 4 1/2 lbs at sea level on a standard day.
On a summer day, it would considerably less at ground level on most airfields in England.
Why? Engine power is a function of atmospheric density. That is why superchargers were invented to slap a band-aid on that fact to try and overcome it.
Of course, some one will stand up to defend their gameshape and think I am slighting their favorite cartoon.
NO, I am only pointing out that Banks chart is a good one for you guys to understand how engines work in airplanes. It is a fact that the 100% power capability of the Merlin II and III is 4 1/2lbs MS gear as listed in all the Pilots Operating Notes.
