That was something the compressor map provided as well as an efficiency map of pressure ratios and speeds. The maps are not perfect but they are better than 'cursing the darkness.' <grins>

I have enough materials and resources to work through a lot of the problems and get some initial metrics. I have yet to find any prior art or a decent model to work from . . . which is reason enough to do the experiment.
