Hi Bill:

 
Its just like Tracy's experience with his Rotary test rig.  With some
twenty years of driving the 911, I had only one BANG.
 
The composite manifold is being widely adopted by Detroit.  They don't
care, nor does PORSCHE, to protect for this rare event.
 
I note  that for our individual FI rotary designs, a composite manifold
could be easier to make and may save some weight.  A POP Off valve
solves the positive over-pressure issue, so we must then only  meet the 
full vacuum (throttle closed) condition.

BTW, what are the comments regarding your auto-aircraft engine throttle
position  - when the cable actuator fails??  I note that all aircraft
engine throttles are designed  to fail WIDE OPEN!!  Auto engine
throttles fail CLOSED.

That is a REAL good point Keith. All it takes is a spring.

There was an incident at LAX yesterday where both cowlings
came off an Airbus engine and hit the side of the fuselage and 
stab during takeoff. The cowlings took part of the pylon 
with them and ripped out the fly by wire throttle control.
Fortunately the throttle failed wide open. The pilot had
to shut off the fuel to make a succesful landing after
the go around.
