If a manual wastegate control would be used, would the system also need an exhaust system to take care of the balance of exhaust not used, like a normalized certified engine?  I would like to be able to use the turbo as an exhaust/muffler. Would you need a stock exhaust and a turbo?

The stock turbo built in waste gate reroutes the waste exhaust gases 
back into the single exhaust pipe. When the gate is open it may be
louder than when it is closed. If you are using and external waste
gate it is usual to use a separate exhaust pipe for the waste
gate. PL 

If my memory should still be working, the POV was set up to a matched rpm/boost ratio that would done by matching the trim to the turbo body. Boost would deteriorate as you went higher at a fixed  non adjustable rate.  The rpm of the iconel wheel would be part of the layout.

What compression ratio would be used on a low boost engine, say five pounds as opposed to the higher boosted engines.  How much octane does it to run a low boost turboed install?

As I recall all the turbo engines use 8.5:1. I could be wrong.
As far as octane I don't know. What are you car guys using?
