[quote="totalspoon"]I/JG27_Waggel, you can't use in game Vb speeds as a basis for calculating the new F IX's speeds are they're not correct.
Both the Spitfire Vb and Hurricane I & II were placed in the game to represent aircraft flying with the Russians (or Finland for Hurricane I) on the early Eastern Front. These aircraft due to lower quality fuel used lower boost ratings for their engines and hence had lower speeds than their western front counterparts.
[quote]When Rolls Royce designed the Merlin engine, it deliberately went against the world trend and used a carburetor instead of fuel injection. While fuel injection provides and easy and precise method of providing the correct amount of fuel for powerful engines it looses the charge cooling effect of a carburetor which added up to 300hp to Merlin engines. Rolls Royce believed that by careful engineering it could work out all the carburetors disadvantages while retaining all of its advantages. With the SU carburetors of 1943, they largely achieved this.
Unlike a WW2 supercharger where the fuel is squirted directly into the hot and turbulent eye of the supercharger impellor, the fuel in a carburetor is vaporized in the passing air flow. For this to occur successfully at high altitudes or high boosts, it is extremely important that a high volatility fuel is used. For the English, the world leaders in aviation fuels, this wasn
