Be wary of sending your supercharger via UPS. We had our blower serviced by Kevin Cantrell, and when he was finished, he dropped it off at the UPS center in Phoenix. Since then, no one seems to know what has happened to it. Kevin has been very helpful in trying to locate it, but UPS has been very difficult to deal with, as if they don't care. If anyone has any ideas on how to light a fire under them, or has any contacts with pull within their organization, please let us know.
