Does anybody know if there is a aftermarket available in the U.S for the R129? My car is fast enough but I want more. I thought about N.O.S but I don't want to put that much stress on the engine. I know that there is a supercharger for the SL but it's only available in foreign countries. My cousin saw supercharged SLs in Japan. It requires/uses an albrex supercharger and the relocation of the coolant container. He emailed me this pic from a japanese website.
