YAMAHA FX-SHO & FZ • SUPERCHARGER
RIVA FX-SHO/FZR
SUPERCHARGER IMPELLERS
Riva Racing released the ultimate (drop-in) performance supercharger
impellers for the Yamaha 1.8 liter SHO Engine! Working closely with Vortech
Engineers, Riva designed these impellers to deliver more horsepower and
torque throughout the RPM range resulting in excellent acceleration and top
speed. Investment cast from an extremely strong, lightweight proprietary alu-
minum and CNC machined to ensure exact tolerances. All new blade design
is optimized aerodynamically and precision balanced to deliver smooth
operation. Installs easily into stock supercharger housing with no
modifications required. Includes detailed installation instructions.
B1 produces 11.5psi @ 7,700rpm • E1 produces 16psi @ 8,000rpm
NOTE: Both impellers require use of aftermarket engine management system
for proper calibration

RIVA FX-SHO/FZ 'H1' RACE CHARGER
IMPELLER & HOUSING
The 'H1' Race Charger was designed for serious racers and tuners who
demand the ultimate performance gains. H1 Impeller and housing combo
delivers 20psi of boost pressure at 8,500rpm producing up to 400hp on modi-
fied engines. High performance impeller and housing combo increase horse-
power through superior blade design and larger interior housing volume.
Impeller features a sophisticated HKS blade design that is precision balanced
for smooth operation. Requires aftermarket ECU and upgraded engine com-
ponents for proper calibration and durability.

SUPERCHARGER SYSTEM
Ever wonder why the supercharger is so HOT? Heat is a derivative of
compressed air (boost). The more boost pressure, the hotter the supercharger
gets. The engineers at R&D understand the key in producing more horsepower
and maximizing performance, is managing heat.
R&D is proud to announce the new Water-Cooled Supercharger Housing
System. The new R&D Water-Cooled Supercharger System is fully water
jacketed and eliminates heat at its source, the Supercharger. The new system
replaces the OEM inducer cover and mounts directly to the OEM
Supercharger body.
The system features a High Performance Volute (intake air path), Internal
Anti-Surge Port, 100% Water-Cooling and a custom R&D Power Plenum Air
Filter. Now since the Supercharger is the coolest part in the engine compart-
ment and runs at lake temperature, it only made since to design a custom
R&D Power Plenum Air Filter that would take full advantage of the new found
cool air, now located directly in front of the Supercharger.
System installs in 45 minutes and comes complete with all necessary
hardware and pictorial instructions.

Up to 200° F cooler supercharger temperature,
cooler and denser intake air, decreased engine compartment temperature,
improved clutch life through Internal Anti-Surge Port, increased RPM (up to
200 rpm), increased boost pressure, improved top speed, no heat fade,=
consistent peak engine rpm.

The R&D Water-Cooled System fits all supercharger wheels that fit
into the OEM charger housing.
