R&D now offers the Ultimate Sea-Doo Surge Protector Kit. The new R&D/Tial 50mm kit works in the same fashion as our entry level surge kit, except its flow capacity is greatly increased. The 50mm diameter with its 6 exit port design releases compressor surge much quicker and more efficiently than any other system available. This means less wear and stress on the supercharger clutch. Compressor surge is defined as the negative charge of pressure that causes turbulence in the supercharger that occurs during aggressive of off-throttle operations. When the throttle valve is abruptly closed at high rpms, the engine decelerates quickly down from 8,000 rpms, however the supercharger is compressing air (creating boost) as the supercharger has to decelerate from 42,000 rpms. This turbulence is the primary cause of undue stress on the supercharger clutch system and its components. The R&D surge protection kit utilizes an automotive vacuum assisted pressure blow off valve that automatically releases the unwanted intake pressure between the closed throttle valve and the supercharger. As soon as the throttle valve is opened, the blow off valve immediately closes and the compressor can supply its full boost potentials to the engine. The R&D kit installs into the OEM intake hose, but for optimum performance, use the R&D Straight Shot Intake Hose (Pt. #613-95257). This kit is a very necessary and cost effective up-grade for all Sea-Doo supercharged watercraft. Kit comes complete with mounting hardware and instructions. For easy vacuum line hook-up use R&D Multi-Port Adaptor (Pt. #613-95270). Pt. # 613-95259 R&D/Tial 50 BOV Kit Retail $399.95 Pt. # 613-95270 R&D Multi-Port Adaptor Kit Retail $125.95
