<VV> Question about stock '63 turbo boost

[G Monrad]

Does anyone know how many PSI boost the stock '63 turbo provided?  

 

The reason for the question is that I also have a Porsche 944 Turbo, and
know what to expect as turbo boost kicks in (and the "Bar" meter approaches
1.0).  With the Corvair, I don't get the same perception of enhanced
horsepower/torque from the turbo as the vacuum gauge goes from -30 to 0.  My
assumption is the Corvair's boost must be less than the Porsche's boost.  

 

What should I be expecting from my '63 Vair? Is it only obvious at highway
speeds?  Can I get the same result at 3K RPM in any gear?
