SURGE PROTECTOR KIT
The R&D Surge Protector Kit will significant-
ly improve supercharger clutch and com-
pressor 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
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 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.

INTAKE 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. stan-
dard 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 manufac-
tured from high performance, turbo charger quality high-temperature silicone.
