I started the same thread in the Engine Modification Forum. Just thought the Roadster crew might have a thought:

I know many of you don't like the Stillen Supercharger due to the hood change, but I ordered one for my Roadster. The hood should be finished on Tuesday and the SC will ship tomorrow. This is the first performance upgrade to my car, so I will be able to see the added performance of the SC alone. After this, I will put the Stillen exhaust on and consider other performance enhancements.

Will my Roadster be the first forced induction Roadster, or are there others out there?

I think I'm gonna get the ProCharger.........it fits under the OEM Hood. Let us know how you like your Stillen!!!
