I've posted a link to the Synapse users manual if anyone is interested in more information about the BOV we have been discussing. Contrary to numerous claims that it is a ricer duck call type BOV, people would be better served to gather their facts before allowing their opinions to validate their ignorance. It is a quality product and can be installed to either recirculate or blow off to atmosphere.
