I am not in on any of the new slot P47 development so I don't know if this is being addressed. I would like to see this in full real mode also for those who are interested in more complete engine management. For accuracy, there would have to be a the possibility of damage due to over-rpm and over heating.

Poncho,

Would love to see this in full real also, but I don't think it will happen. You'd have to have a way to control the turbo waste gate at different power settings. I'm not even sure if P47 pilots had to worry about this. I seem to remember reading something about it being automatic. Just the S/C, Water Injection, Mixture and Throttle were controlled by the pilot. Will check my reference materials again and let you know for sure.

S!


OK, now I’m confused again, The turbosupercharger has a compressor driven by the crankshaft, and a compressor driven by the exhaust gas, right?. What is controlled by the s/c lever? And what is relationship between the s/c lever and the turbo rpm gauge/light? I had assumed (maybe incorrectly) that the turbo-rpm was managed by adjusting the s/c lever.
At one point I was looking into programming a functional turbo overspeed light. In my research into how it should work, I found that:
Light off = turbo rpm below optimum
Blinking light- rpm in optimal range
Light solid on= over rpm.
I remember seeing somewhere that the rule of thumb for the pilot was to “keep the light blinking”.

That suggested pilot management to me.

The S/C lever controls the gearing stage for the super charger. In the game it's automatic, but I believe in real life it was controlled by the pilot.
As far as the Turbo Light, your theory is sound, but since the turbo is driven by exhaust gas, you should be able to control it through the use of RPM (Prop Pitch). Less RPM is less exhaust.
The only other thing would be the use of some kind of a control for the turbo waste gate. I'm still checking on this to see if it was pilot controlled or automatic.
