Re: S281 Saleen Question
The supercharger was optional on the 96-04 S281's. Yes, they did offer a non-S/C version, basically the body kit and suspension. At least on the 99-04's, the non-S/C cars came with under-drive pulleys and a chip. Easiest way to tell the S/C from non-S/C cars is look for the heat exchanger in the center opening of the front bumper.
For the 05+, they also offered S/C and non-S/C versions.
