PERFORMANCE BLOW-OFF
VALVE KIT
Our Performance Blow-off Valve Kit improves
supercharger reliability and performance by
relieving unwanted pressure during off-throttle
operation. Reduces supercharger clutch & gear
wear and eliminates heat soak in discharge
tube. High-strength silicone hose with integrated
HKS valve installs easily in place of OEM elbow joint. Includes high quality
HKS Super SQV (Super Sequential Blow Off Valve) that features unique
sequential valve structure and a differential pressure control system, allowing
for a broad operation boost range. Also includes vacuum line and fittings
necessary for installation on SHO engine. A simple and cost effective
upgrade for both stock and modified engines.

R&D SPECIALTY
SUPERCHARGER TOOLS
R&D has designed a custom tool kit that is
essential in the rebuilding process of the
Yamaha Supercharger. All tools are specific
in application and are cnc machined to
ensure a precision job.

CLUTCH REMOVAL
TOOL
This R&D tool enables the clutch to be
changed in a matter of only minutes. With
the supercharger and front engine cover
removed the tool drops down through the
case and secures the drive gear at the
front of the crankshaft from rotating when
the clutch is removed and installed. This is
a “must have” tool that will save massive
amounts of time for any mechanic.

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 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.

VALVE & FILTER KIT
The R&D Billet Surge Protector
Valve and Filter Kit is now avail-
able. The billet aluminum CNC
machined valve is an optional
bolt-on replacement for the plastic Bosch valve used in the R&D and other
aftermarket surge protection systems. The o-ring sealed billet design offers
improved consistency and performance in higher boost pressure applications.

R&D GReddy Blow Off Valve
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, we recommend the Type
RZ for 100-400hp.1" Hose adaptor sold separately.
