What we should expect from the next patched Blenheim engine model

[phoenix1963]

I quite enjoy struggling with the current over severe engine model, but here are some pointers for the devs:

Improved cooling: The manual clearly states that takeoff is to be performed with closed radiator flaps (gills), this suggests to me that CHT (cylinder head temperatures) should not exceed 240C for a starting temperature of 180C (not currently achievable with closed gills). Likewise, level flight should be able to be performed at cruise settings with fully closed radiator flaps at all altitudes.

Similarly, I suggest that typical taxiing power (say, -1lb?) should be able to be used indefinitely on the ground (i.e. near zero airspeed) with open radiator flaps. Also, climbing at 5lb boost and 130 mph with open flaps should give stable CHT.

This gives the devs useful boundary conditions for the amount of waste heat that is successfully transferred out of the engine at a variety of engine settings, airspeeds and the two extremes of radiator flap settings. The current model (particularly with closed gills) simply does not reflect the reality of the record.

Improved boost: The manual clearly states that +9lb boost can be used for takeoff until 120 mph is reached. The current engine model is too fragile for this.

Oil temperature: Using the (inauthentic) intermediate pitch settings, it often seems difficult to select throttle settings for level flight that allow both the CHT and oil temperatures to remain within normal limits (even using the radiator flaps to adjust). The problem goes away when coarse pitch is selected (indicating a programming "fix" to the problem). Surely this is not authentic and the oil temperature (or engine sensitivity to it) must have been less of a problem?

Flaps: We must be able to select intermediate settings.
