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
decelerate 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.

R&D/TIAL 50MM SURGE PROTECTOR
R&D now offers the Ultimate Sea-Doo Surge Protector Kit. The new R&D/Tial
50mm kit works in the same fashion as our entry level surge kit, except its
flow capacity is greatly increased. The 50mm diameter with its 6 exit port
design releases compressor surge much quicker and more efficiently than
any other system available. This means less wear and stress on the super-
charger clutch. 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 supercharger is compressing air (creating boost) as the supercharger has
to decelerate 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 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.
The R&D kit installs into the OEM intake hose, but for optimum performance,
use the R&D Straight Shot Intake Hose (Pt. #613-95257 see page 13). This kit
is a very necessary and cost effective up-grade for all Sea-Doo supercharged
watercraft. Kit comes complete with mounting hardware and instructions. For
easy vacuum line hook-up use R&D Multi-Port Adaptor (Pt. #613-95270).

R&D MULTI-PRESSURE PORT BOOST
GUAGE/SURGE/RRFPR ADAPTOR KIT
The R&D Sea-Doo Multi-Pressure Port Adaptor Kit will allow quick and easy
“BOLT ON” installations of Rising Rate Fuel Pressure Regulators, Tial/Greddy
type surge valves, as well as digital or manual boost/vacuum gauges. The
R&D Multi-Pressure Port Adaptor installs smartly between the OEM Map
Sensor and the Sea-Doo intake manifold as a “bolt on” part with no drilling
modifications. The R&D adapter has two large volume ports that allow for
proper installation and operation of a vacuum/boost gauge, surge protection
valve, and boost referenced fuel pressure regulator (RRFPR) all at the same
time with one simple part. The R&D Pressure Port Adaptor Kit comes
complete with all mounting hardware and instructions.
