If a manual wastegate control would be used, would the system also need

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. DL

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?

Barny

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?

Paul, the 89-91 Turbo II used 9.0:1  compression rotors as do the 13B REW,
the 86-88 Turbo I used the 8:5:1.  If the automobiles could run 5-7 boost on
87 or 93 octane I would think the 100 LL would be safe for those boost
levels - but just speculation on my part at this point.
