Honda seems to have copied the BMW turbo compound idea: but put an generator
in the loop. Not so smart. Gee for the money they spend on some of these
projects they could fund us 100 times over.

Speaking of turbo compound. Hey Francois lets make this T.C. a group effort.
Why don't you sell me this turbocharger sans compressor at cost for my turbo
compound research? Your company would benefit greatly from the data and if
it works you could offer a turbo compounded version.
Here is what is my plan.
The larger ROTREX 1:7 ratio (max 70hp input) traction drive can be modified
to run in either direction. Its output direction is opposite of its input.
Mistral turbo-charger runs clockwise when looking at it from the bell
housing side of the engine. The engine runs counter clockwise when looking
at it from the same perspective. The traction drive doesn't care which way
it runs. Modifications entail remaking and reversing the threads on a small
rectangular drive plate as well as a short and simple drive shaft. Next the
the oil passages have to be switched so the miniature vane pump will work in
reverse. Finally the turbo compounding unit would need a connection housing
between the turbine oil intermediate housing and the traction drive. In
essence the traction drive will have to be able to mount as if it was a
compressor. This connection housing will have to be milled out of a block
of aluminum. Is the Mistral turbine and the Rotrex the cats meow? Probably
not for various reasons but for proof-of-concept it sure the heck is.
Here's why.
Bringing the power via a multi-ribbed belt into a pulley mounted within the
bell housing on the e-shaft with an engine stabilized 6000 rpm would entail
a 2:1 pulley ratio, or a 5 inch pulley on the e-shaft and 2.5 inch pulley on
the traction drive output. Stabilized turbine speeds would then be 90,000
rpm. Different size pulleys ratios could raise or lower that number.
For a bench test output measurement, an eddy current generator should be
used. This would entail asking for Mazda Corp's help. of course.
