Absolutely not. Corvair engines should be as near silent as anything  out 
there, especially when at speed. Noises add up, so I'd start hunting  with a 
stethoscope.

yea. Vairily ...  Shaun



Exhaust noise can be controlled or ignored on either water or air-cooled  
motors. A front engined car has a bit more real estate to work with to dilute  
and muffle the sound.  Engine noise, the sound of the ignition and burning  
inside the cylinder, will make it's way out of the engine compartment. Water  
Jackets, both in the head and the block, provide some sound deadening that  
air-cooled motors just don't have. My late mother could recognize a Porsche 911  at 
a distance, not by the silhouette, but by the engine sound, and she was no  
car nut. Of course, she could hear me sneaking into the house after midnight, so 
 I was not surprised!
