Here's the thing, Wes... your posts are so haphazard and strung-together that I can't tell whether or not you have a finished product for the 944 that is ready to be sold and shipped. This is not a slam; most good engineers don't think like writers!
Now, I see you listed a price of about $895. I would assume this is just for the supercharger, and then you would recommend upgrading ignition and supplying your own belts and pulleys?
I think you are doing great work, but your posts can be kinda hard to follow, no offense.
