Has anyone ever done work or looked at how much power can be loaded onto
the front end of the E-shaft. I imagine there is currently 5-10 HP
running accessories, but it seems to me that one could load that with
quite a bit more, even possibly half of the HP output?
Am I wrong here?

No I don't think you are wrong if you don't put any side loads on it.
I was going to drive the prop with it but I would put another bearing
on the over hung side load. Maybe it would be best to do a whole new e-shaft
and front cover for this application.

Paul & Michael,
What is your application Michael? The (almost) straight thru e-shaft
should be able to output, or input, significant hp.
The reason I ask is, for shaft mounted (or low ratio) turbocompounding
applications. To reduce heat effects of a shaft mounted turbo
compound mechanism, it may be better to mount on the "front", ie. not
major pto side of the engine, to reduce heat effects to the engine and
PSRU.
Several builders have gotten very good results, to solve heating
problems, when they used the exhaust stream as a "velocity increaser"
within a duct for the cowl exit air. This may be a big advantage when
the final takoff of the exhaust is on the opposite end from the prop,
ie. turbocompound exit, opposite from the prop. This gives more
distance to bend tubing the way that is best for a "velocity increase"
design. Our application is for a pusher so I want the exhaust to curve
around to the front, and then exit to the rear for best air flow in the
cowl.
