retrofitting high compression, turbo-charged or other high

The government and private organizations are working on it.

Jim - Are "they" really working on it? I wonder just how many
aircraft engines are under serious test and in what lab is it being
done. I have a funny feeling that there are none. It certainly has
been quiet out there except for the hand wringing.

Given the ongoing number of naysayers etc after 20 years of autofuel
experience, how long is it going to take for everyone (fuel and
airframe manufacturers, lawyers, repair shops, engine suppliers, etc)
to endorse a financially acceptible substitute for 100LL without major
engine modifications or even engine substitutions.

Personally I don't think it is going to happen.
