<VV> 1966 turbo

[FrankCB at aol.com]

Not much need for the "other Frank", since you did such a good job  already!!
In fact, all I can add is a recommendation to get the "Corvair Basics"  
manual from CORSA and study the chapter on turbos to fill out further details on  
what you've already summarized.  (Of course, I may be a "little" prejudiced  in 
that matter.<GGG>)
    Thanks for beating me to the punch, Frank!!

The  other Frank will be along shortly!

For boost, everything else needs to  be in  good condition.

1. No exhaust leaks from the exhaust  manifolds to the turbo exhuast housing.
2. No leaks from the compressor  housing to the heads. This means 
checking the rubber hose and the gaskets  on the head at the chrome 
crossover.
3. Throttle opening all the way.  When you step on the gas pedal, the 
throttle has to be fully open. Need  two people to check. The bellcrank 
on the side of the carb should go to  the stop.
4. Ignition system needs to be working properly to develop boost.  It 
doesn't seem related, but if the engine is running poorly, it can't  
develop enough exhaust  flow to spin the turbo.
5. Carb. Despite  comments here, the Carter YH can work and develop 
boost. But it does need  to work as properly as it can.
6. Does the vacuum/boost gage read varrying  vacuum when normally 
driving? If not, then the plastic hose may be  broken.
7. Exhaust system needs to be clear of restictions. Check for mouse  
nests after this long storage period. Inside the muffler!
