I've heard about this hissing issue many times. I'm curious to learn why some installations have the hissing sound and others do not. Maybe @BergmanAutoCraft can comment?
My car is the blue car KernDog posted above. Smaller AC pulley, hydraulic cam, Saginaw PS pump with external pump cooler, less than 500 miles since Borgeson box install and no hissing.
