Does anyone have any performance numbers for an IO-320 and a Constant Speed prop? Power settings, fuel burn, etc?
Thanks!

Paul,
The attached table was derived using Kevin Horten's python code (thanks
Kevin) but with the parameters taken from the IO320D&E chart in the OM.
The figures marry up to the charts within the accuracy of my eyesight.
Is this what you were after?

That is a sweet chart. I assume this is the information you can put into EFIS's like the GRT HX to readout real time power? I haven't actually looked at this configuration yet on the HX.
Has anyone run a chart for an IO-390?

I believe the GRT units take the data in a different form - see the GRT_EFIS Yahoo group has a number of such tables. I don't have a GRT EFIS so I cannot give a more detailed response.
Kevin Horton's algorithm computes the power by interpolating the Lycoming plots and doing some pressure altitude corrections arithmetically.
The Lycoming plots are believed to be the product of extensive engine tests and I assume are accurate BUT only for the respective engines. I doubt such plots will ever be available for the 390 or any other modified or experimental engine. BPE is one company that does test engine modifications and may have done some tests. Even if they have I doubt these would be anywhere near the extent necessary to generate the Lycoming style plots. Further ... the chances that your 390 would be the same as any test article is extremely small.
