============================
Smitty Says;    You are right Ray.  The carb and muffler in a stock turbo 
Corvair setup are both restrictive.  A big carb is always an asset for turbo 
performance.  Anybody that thinks a restrictive muffler aids Turbo 
performance simply does not understand how a turbo works.  The Ideal is to 
get as much pressure drop across the turbine wheel as possible and that is 
accomplished by a NON restrictive muffler.  My NSHO is that they did not 
recognize the absolute durability of the turbo engine they had built and 
they did not want thousands of warrenty claims laid at their doorstep.
