Paul,

For those who have no desire for high altitude performance wouldn't
a turbo drive to traction drive without the supercharger be much
less complex and easier to manage? I have not been paying adequate
attention to this thread even though the idea is certainly intriguing.
Would the power gain in such a simple? configuration be worth it?

Another question, why not a coil spring coupling to the traction
drive to accommodate misalignments?

Fred O.

Sure. It would work of course. The only thing you would lose is the compressor.
You still need the turbine. Why bother? Why not have more power at high
altitude? Even if you never get over  7000 feet you would still get a
benefit from the compressor. You would have to make something to take
the place of the compressor housing if you used a stock turbo charger
for the turbine section.

Sure a coil spring coupling would work. The torque is only about
2 foot pounds or 24 inch pounds.
