BlexusGS Posted March 26, 2008 Share Posted March 26, 2008 This is OLD news...very old. If you go on other forums like Club Lexus you will see that MANY have this RMM supercharger back from '01, '02 and '03. RMM discontinued this application back in 2003. So did SRT and LMS. They too had superchargers out at one time for the GS4XX. Now, you MUST find one used in order to get one or custom fit a new type of supercharger. BTW, the RMM was a Vortech supercharger that yielded 8psi with a 3" pulley. There are some guys with GS4XX's hitting 380whp+ with this setup along with 370cc+ injectors and upgraded fuel pump. GL!
