Glenn Dickinson of R&D has just informed us about the recent tests of the new Supercharger housing that was carried out in Havasu with his partner Bill Chapin. According to his update report there were significant differences to the Cooler charger temperatures that improved the overall performance. Cooler intake plenum temps, improves clutch life by less surge through Turbo style internal surge port, cooler engine compartment temperatures. Increased rpm (200+ over heat soaked OEM housing), improves top speed, no engine heat fade, and consistent peek engine rpm, and lowers block temps. The OEM charger housing temp is 230 degrees F (in short run), and reaches 280 degrees F in long run. The R&D water-cooled housing results in a lower temperature of 80 degrees F (consistent long or short run). According to Dickinson the new housing is better in every way. Bill and I are very pleased with the performance improvements Glenn reported and soon this product will be available from R&D for the Yamaha enthusiasts and hard core racers. The new R&D Supercharger kit for the FZR/SHO comes complete with new custom R&D Power Plenum Air Filter.
