One thing we tend to forget- we operate these motors over a wide RPM range.
So you need to figure out what engine RPM range you want to optimize
fan performance at, select fan drive ratios for that, and then determine
if fan performance is ok over the rest of the RPM range.
If not, adjust and recompute.
