None of the hoses on the intake side are blown off. I did a fairly thorough visual inspection of the engine bay yesterday as I was replacing the header and didn't notice anything out of the ordinary.

Maybe it has a leak and when the supercharger starts pulling a lot of air in, the vacuum closes the hole.

Assuming the recirc valve is the infamous bypass valve that seems to kill itself so often on these units, this is definitely a possibility. That said, I'm not sure how likely that is considering this is a brand new unit.
