Description
 
The R&D Yamaha FZR Surge Protector Kit will significantly improve supercharger clutch and compressor wheel performance and reliability by eliminating damaging compressor surge. Compressor surge is defined as the negative charge of pressure that causes turbulence in the supercharger that occurs during aggressive deceleration or off-throttle operations. When the throttle valve is abruptly closed at high rpm’s the engine decelerates quickly down from 8,000 rpm’s, however the supercharger is compressing air (creating boost) as the supercharger has to decelerate from 80,000 rpm’s. This turbulence is the primary cause of undue stress on the supercharger compressor wheel, intercooler, clutch system, and its components. The R&D Yamaha FZR Surge Protection Kit utilizes an automotive vacuum assisted Bosch pressure blow off valve that releases the unwanted intake pressure between the throttle valve and the supercharger thus keeping the pressures in P1 and P2 equal. 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.
Features
  • The R&D surge hose is manufactured from high performance, high-temperature silicone with an integrated molded riser for the blow off valve to function without hindering intake flow or velocity. The R&D kit installs easily in place of the OEM rubber elbow joint with no modifications. The R&D Pressure Port installs between the MAP sensor and the MAP sensor bracket with a “bolt on” part. The R&D Surge Protection Kit is a necessary and cost effective upgrade for the Yamaha FZR supercharged engine. The R&D kit comes completely assembled with silicone elbow, blow off valve, R&D B.O.V. filter, mounting hardware and instructions.
