R&D RXP/RXP-X/RXT/RXT-X
GTX-SC SUPERCHARGER
SURGE PROTECTOR KIT
The R&D Surge Protector Kit will significantly improve supercharger clutch
and compressor wheel performance and reliability by eliminating compressor
surge. 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 super-
charger is compressing air (creating boost) as the supercharger has to decel-
erate 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 Bosch 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.
Manufactured from high-temperature silicone hose 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 intake elbow joint.
This kit is a very necessary and cost effective up-grade for all Sea Doo
supercharged watercraft. Kit comes completely assembled with silicone
elbow, blow off valve, R&D B.O.V. filter, mounting hardware and instructions.

HOSE KIT
The R&D Supercharger High Performance Hose Kit was developed while
testing the R&D Monster Compressor Wheel Kits. Higher boost pressures
create higher intake air temperatures of up to 235 degrees. The O.E.M.
standard black rubber hose and standard hose clamps just do not hold up
to the pressures and heat like high quality, high temperature silicone hose
and high strength stainless steel style hose clamps. The R&D “Blue Hose”
is manufactured from high performance, turbo charger quality high
temperature silicone.

R&D Greddy Blow-Off
Valves are easily adjustable
to eliminate compressor
surge and preventing
premature boost leakage,
while increasing boost response. Each valve is made of durable cast and
billet aluminum frame and the valve to diaphragm ratio provides performance
that cheap piston types cannot offer. The spring stiffness adjustment screw
and the three different sizes give the Greddy user the option to match
vehicles with mild upgrades to heavily tuned engines. There are many factors
in matching a blow-off valve to an application, valve location, turbocharger-
supercharger size and pressure, but as a general rule of thumb, R&D
recommends the Type RZ for 100-400hp applications.
R&D 1" Hose adapter sold separately.

Valve kit comes complete with R&D high temperature silicone hose, Tial
50mm blow-off valve, billet aluminum V-clamp, banjo style vacuum fitting, and
1/4” vacuum line.
• 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
Modification required for installation on Sea Doo PWC.
