Fw: Pop Off Valve

[Bob Wooten]

vortech uses one on the LS1 kit that they have for the F bodies, that does
not have any wires or vacuum lines going to it. it looks just like some
that i have seen on turbo applications, but vortech is porting the gas back
to the intput to the blower, don't know why though.  i cant imagine that
they are that cheap though.
