I have read all twelve pages and I will respond with.......Wow. This is a very interesting supercharger concept and a very tempting package with reasonable pricing.
I am slightly confused however regarding the mounting of the supercharger itself. During the first seven (or so) pages of this thread the supercharger was going to mount on the intake side, cold-side, and require the need of a re-designed intake manifold (which I would prefer) and the last few pages discussed the supercharger being mounted on the right side, hot-side of the engine. Which is it? Or, do we not know that for sure yet?
My only lingering concerns would be regarding the longevity of the components of this kit, product support and the EM used to fuel the extra injectors.
I will continue to watch this thread very closely as I am interested in the developement of this product.

DO NOT ASSOCIATE THE PICTURES I POSTED WITH THE WAY THE COMPRESSOR WILL FINALLY BE MOUNTED.
This was just me being board and just messing around with some designs.
Most likely it will be mounted similar to the way Comptech/Vortech has there setups mounted; as this has been proven a viable mounting solution.

Chuck take a look at this might not need to build the thing we were talking about.
woud be nice to get a hold of a rotrex step up design, put one of the following linked ideas on the Rotrex step up design and then intergrate it with a standard AFSC8

I'm still coming to grips with all the possibilities opened by current CNC technology. I guess you could build a drive with an infinitely variable ratio and run the blower at a constant speed if you wanted to deal with the complexity.
An AFSC plus "controller" seems a lot simpler. How much effeciency would we gain with the two-speed drive?
What are the other tradeoffs?

Not much efficiency would be gained using the step up vs our idea; it just gives you a better boost profile through a different method.
Note this clutch does induce more mechanical losses in the system due to the design however theses losses are usually over come by the added boost profile.
The other problem with this step up is it is a discreet change between the two gear ratios.
Think of an automatic transmission there is a sizable drop in RPM after the shift.
The way Rotrex does there

Does anybody else care about weight, more importantly, weight forward of the front axle? I don't want a centrifugal supercharger kit mostly because of the power curve, but also because of their mounting position and additional weight of the intercooler setup all of which is forward of the front axle.
This setup and the FFS setup are very promising if they can keep the weight of the components behind the front axle so not to upset the handling balance of the car.

On an MY00 AP1 like I have, any additional understeer is a plus, but honestly, the weight of the supercharger didn't change the handling of the car as much as I'd expected. The aftercooler doesn't weigh much, but the supercharger and bracket are pretty heavy, and it's all out front, so I expected substantially more understeer. Didn't turn out that way though. We've dialed in a little more under since then (remember, it's an early AP1 
) to get the car to handle the way we wanted.
Richard's AFSC offers lots of (potential) advantages, including lower weight (regardless of where it's located), but even the Comptech SC/AC doesn't make a *huge* difference. To me it feels like less of a difference than there is between an AP1 and an AP2.

And true, this supercharger setup is lighter than any other blower on the market, or soon to be market.
A few years back I owned an A/A intercooled BRP supercharged '03 Miata. The added weight of the supercharger did not effect the handling too bad. The added performance far out-weighed the weight increase.
