<VV> turbo mufflers on a 140

[Mel Francis]

The original carb and Turbo itself, was sized small to be the main boost 
restriction.

Limiting the boost in this manner,  it didn't require a wastegate.
A Corvair Turbo engine will not self-destruct if it is run without it's 
muffler.

Turbo mufflers came into wider use by performance enthusiasts looking for 
less
exhaust backpressure, not more.
