Lots of tuners go for the magic number of 380. That way if you are tuning the car in a pretty hot atmosphere, you won't potentially hurt the car when you are running it on a nice colder night. It also doesn't put a lot of strain on your rods and pistons, which are the first to go usually.
Remember, you can't have underdrive pullies on with a s/c (for future reference)
Procharger told me with midpipe, catback, throttle body, and plenum I am freeing up 1.5 to 2 lbs of boost. One of the most important things with s/c applications is a custom tune and just make sure the guy knows what he is doing. A lot of it is down to timing. For example, i have a D1SC which already makes 3-4 more lbs of boost over the P1 and am at 13lbs at 383rwhp where a lot of people are around 8 at that hp. It's just a difference of timing. But you can't just go up to 20lbs :P

I think they only sell 70mm and 75mm TB's. For forced induction I would go with 75mm.
I went with a Professional Products 75mm throttle body and an Accufab plenum.
Accufab is pretty expensive but they are better than the competitors and it looks really nice all shiny and ****. I personally didn't see the purpose of buying such an expensive Accufab throttle body. I didn't see how it could be THAT much different than competitors for the fuction it serves. I did however think that a more expensive plenum would be good since the air is in it longer and the better curve/smoother it is the better.
Be prepared though, if you are going s/c then you will need quite a bit of supporting mods and it's not cheap.

90mm maf or some sort of blow-thru maf
42# injectors or 39# cobra injectors with adapters (they were tested at 43#'s)
SCT tuner or something similar
Degree colder plugs (NGK TR6's or equivalent)
At least boost, wideband gauges
I found a great deal on a supercharger and ended up buying all the supporting mods and all used for around 2500 bucks.

With respect, why do I need those above mentioned mods? What do they do for my car/blower?
