What is the input data for your calculation?
- clmax (or stall speeds used + source)
- cdo (or power output, boost, rpm and speed + source)
- weight (source)
- assumed wing efficiency
- assumed prop efficiency
I would think the relation is about OK, but both planes are turning too fast and I also think that the high speed relation is a bit off.
