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.

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
