 Colyn,
 
 
 Thanks for the input.  I was thinking that if I were to lose both turbos that
I'd have a NA aircraft, but with one still running I'd have half-boost minus
some loss.  Seems like this is a condition that someone has already evaluated
either on a test stand or on paper.  Oh well, I'll keep looking!
