situation. BTW, I have located a planetary gear set with 2.4:1 ratio. It

is used in a Borg Warner35/40 transmission, very common in  Falcons,
Valiants Toyotas and Sigmas and even some 6 cyl Jags in the 80s.

What sort of  HP can thePlanetary handle and what did it cost you.

The Jatco auto transmission used in  Toyota's and Mazda's is a scaled
down version of the C6. Jatco is jointly owned by Ford and Toyota.
One of the reasons the C6 is so popular for PSRU's is the main part like
the planet carrier is a separate piece. This, compared to say
a GM automatic, makes it easy to design a PSRU around. The Jatco
has this in common with the C6.

Here is a picture of the Jatco and  C6 parts for comparison.
sorry about the quality of the pictures. As you can see
there is a wide selection of C6 parts and their derivatives.
 
The Borg Warner35/40 transmission I would guess is probably stronger
than the Jatco as the Falcon six is a pretty powerful car.
At least the one I drove all over Tasmania was. I liked it a lot.
Nice car. Not as powerful however as a 7 liter U.S. Ford V8
or an F250 turbo diesel pickup truck that uses later versions 
of the C6.

Having said all this I want to warn you that the main issue
is the torque pulse amplitude out of the engine and not so much the HP.
If you are thinking about scaling down the PSRU because you
are using only one rotor I would advise caution. The torque
pulse is the same amplitude. Just half as often. It also goes
negative unlike a two rotor engine.
