REFLECTOR: Update on my Subaru installation

[Sid Knox]

I have to disagree here... the seal is working against a spring, not ambient 
pressure.  Therefore, altitude is not a factor, or at most, a minor factor.

I really should read these things before I hit send.  I should have said a 9 
psi cap at sea level or 24 psi absolute pressure.   That 14 psi cap would 
give about 29 psi absolute at sea level.  A 20 psi cap should handle things 
to 12,000 plus feet.

Alex,

At 10,000 feet you lose about 5 psi of atmosphere making your 14 psi cap a 9 
psi cap absolute pressure.
