All rights reserved. R&D FX-SHO/FX-SVHO/FZR SURGE PROTECTOR KIT The R&D Yamaha FX-SHO/FZR Surge Protector Kit will significantly improve supercharger clutch and compressor wheel performance and reliability by eliminating damaging compressor surge. The R&D 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. 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 FX-SHO/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.

Description Part No. RIVA FX-SHO/FZR Blow-Off Valve Kit RY17040-BOV-SSQV R&D/TIAL 50MM SURGE/ BLOW-OFF VALVE KIT R&D announces the release of the new R&D/Tial 50mm Surge/Blow-off Valve Kit. R&D has been committed to on going research for any part that proves to be an aid in reducing the inherent and well known clutch issues related to running high performance boost wheels and high boost pressures in the Yamaha 1.8 Supercharged engine. R&D has noticed a significant reduction in clutch related issues in high boost ranges by “Going Big”. R&D engineers have concluded through endurance testing that the new 50mm R&D/Tial Valve with its huge 50mm lightweight billet alu- minum piston, and 6 massive (bigger than any other valve) pressure relief ports, to outperform the smaller (25-35mm) HKS Sequential, and 35mm Greddy RZ Valves. The trick R&D has found with this valve is, in aggressive off throttle situations with a gear driven supercharger the big Tial 50mm piston responds quickly to allow the reduction of boost pressure which relieves back pressure that can affect the clutch. The new 50mm design also has a much larger diaphragm over HKS and Greddy, which helps the piston react quicker to relieve pressure. If you are running Boost Wheels that produce over 15 pounds of boost, R&D strongly suggests looking into a larger valve setup. It only stands to reason that with higher boost pressures, a larger valve can allow quicker discharge of air volume. Valve kit comes complete with Aluminum weld- on adaptor, o-ring seal, billet Aluminum V-clamp, and banjo style vacuum fitting. • Aggressive throttle response, increased horsepower from a better seal • Increased boost pressures over smaller valves that don’t seal well • Improved valve action with larger diaphragm and variable spring control • Improved clutch performance from reduced off throttle back pressures • Precision sequential valve operation • Installs easy and clean to the OEM intercooler inlet/outlet • Works well on R&D Pro Series Intercoolers Description Part No. A.
