R&D FX-SHO/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/BLOWOFF
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 aluminum
piston, and 4 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 O.E.M. intercooler inlet/outlet
• Works well on R&D Pro Series Intercoolers
