I need a reputable place to order a super charger from

[StreetStang37]

I need a good reputable place to order my super charger from. It's not concrete but I'm pretty sure I'm gonna get an A-Trim. I've called Excessive Motorsports and they said it would take 2 weeks or so. Where should I order from? Also, what different pullies are there to bump up the boost? An 8# pulley and 10#, right? Is there one for 9#'s? Which should I get? Will running it at 10#'s be a good idea? Will a power pipe bump the boost more? You guys know what works. Thanks in advance.
