I would really like to thank everyone for your input! Due to your suggestions/thoughts/experience/etc., I've found a local shop in NJ (East Cost Supercharging) that has significant experience supercharging LS engines and also I've shifted my thoughts on S/Cs from Vortech or ATI to Magnusson.
Shinkaze your two cents are directly in line with Chris' from ECS. I was a little concerned about the hybrid Magnusson having only heard that from one source (being Chris at the time), but your input raised my comfort level. I’ve also received a similar recommendation today from Thunder Racing.
Chris from ECS is supposed to call me back when he gets a date on the Magnusson (he's thinking the next few weeks). And he's guessing in the $7K – lower $8K range. I also asked him about a group purchase like several of us did with BMR. Anyone interested?
I'm very interested, but Sadly I have to buy the V first
FWIW at this point I'm leaning more toward the V than the 545 sport, but it will still be after Thanksgiving before I get mine.
The Mag. with intercooler would be the best bet. A friend put a Mag kit on an H2 and this thing is a monster . Spins all 4 wheels . Tons of power . I talked to Magnuson , Superchips who does their Re-Prog. and East Coast. I would say the timeframe for a real kit you can buy will be the Nov. timeframe. But that give plenty of time to upgrade the wheel hopping suspension!!
I don't think you will get much of a group purchase break on the Mag. kit but hey let me know. I doubt I will go for it since the car is not a fall/winter driver, but I'd definitely like to see the finished product so I'm glad 2 people near me are considering it.
Keep in mind you will have to do away with the strut tower brace and get a new hood for the Mag to fit in there. But the low end torque on that kit is absurd.
You nailed it on the head Shinkaze. Eatons come from the factory on Fords and GM's with nary a peep of problems. The other brands of superchargers are afterthoughts, not integrated systems like the Eaton.
Also remember that the engine lower end and drive train is typically beefed up by the factory to handle the additional torque and power output gained by supercharging. This is a part of their trouble free operation. More boost means more power means more demands on the cooling system too, particularly if you use it for supplying the intercooler. If the V is already running near the edge on cooling capacity, supercharging could easily push it over the edge. It might be worth checking to see what Eaton or Magnusun recommends.

Re: Which supercharger would you recommend?
My friend owned a Pontiac Bonneville with the Supercharged V6. The supercharger failed ab 38,000 miles. I haven't heard much of encouraging experiences with Turbo Chargers either. Reliability problem or just pushed too hard, I do not know. Therefore I sincerely appreciate a naturally aspirated engine with lots of horsepower and torque designed in.
Don't think you will fit any type of top-side brace over that supercharger. You could go with sway bars underneath or something, but I think it's pretty much out of the question without some massive hood that looks ridiculous.
If you look closely at the rear of the blower you can see that it is sitting about 1.5 - 2" lower than the cowl. I bet someone (ahem...bmr) could fab up a strut tower brace that would be able to fit in that area to be used with this kit. Or maybe triangulate with the cowl for even more strength. I have seen some other cars that need to do something similar.
