Dave and Bill,
Bill I think the Mistral has a SAE 2 prop hub but I do not know what hub the IO-540 has..........The Mistral PSRU
has a slightly different ratio of about 2.8235 to 1..........Totally different gear set with no relation to the Ford parts
used by Tracy............Take a look at photo below..............
Dave I agree it is too bad they did not aggressively pursue us experimenters to get their engines in the air as
it would have given them all those engine hours in the air essentially free to prove out all those Dyno hours.......
The links below will give you the Mistral numbers..........I do not have the Lycoming numbers...........

I was under the understanding that the Mistral engine had an SAE 2 prop hub. The hubs are certainly not the same on these two engines!!??
The ratio is the same, but is the Mistral PSRU based on the same gear set as Tracy ’s PSRU?

Interesting comparison of packaging between the Mistral G-300 (Cosmo 20B, 3 Rotor to us) and the
Lycoming IO-540 engines...........
