All the talk of "Thrust" from a radiator is unfortuante use of terminology. The Mustang radiator combined with the fuselage design to deliver a radiator system which created less drag in effect allowing more of the engine/prop thrust to be used for more speed.

There is simply not enough heat being dumped into the cooling aird stream to create real positive thrust. This effect does occur at supersonic speed in the ram jet engine, but the Btu value of fuel being injected is substantially higher and the ram effect of the supersonic wave also comes into play.

Plus, it is not an effect that is necessarilly linear. As good as IL2 is, I find it unnecessary to expect Oleg and his team to model all the planes to the n/th degree. We all appreciate the great sim effort being put out and the support to enable tweaking and adding-on over time.
