Another question. I talked to someone at Oshkosh who was selling
chain-drive reduction units for V6 conversions. He indicated
that they have quite a bit of flight history and seem very reliable.

In the early days of drag racing, an number of people tried driving
their blowers with this type of drive. (single & dual links)
For one reason stated by Paul, they faded away. (weight)
Including centrifugal force attempting to throw the chain
into oblivion.
The chain is a great positive, high load device, but not high rpm,
unless you go to a link-belt system, and then at least doubling
the original heavy weight.
As Paul indicated, why bother?
