My Hooter valve legs are reversed ... Posted by Gene N [Email] ![]() ![]() ![]() In Reply to: Hooter orientation: Should the two 90 deg legs be interchaged ?, Daren, Mon, 18 Jun 2001 16:43:24 Members do not see ads below this line. - Help Keep This Site Online - Signup |
from the one in the picture and it works fine. As far as I know, it was that way when it came from the factory, although it was replaced once by an independent that has been working on SAABs for 30 years. In the configuration in the picture, the vacuum pull has overcome the pressure in charging pipe to open. If the legs are reversed from the picture (as they are in my car) the pressure helps open the valve. That's why people who increase their boost beyond 20 psi have to get a high performance valve. At very high boost values, the pressure overcomes the spring and opens by itself.
