RIVA SD POWER COOLER
The RIVA Power Cooler is a significantly improved intercooler system for
the Sea Doo 215hp Intercooled Supercharged 4-TEC engine. Delivers
an increase of 15-peak horsepower over original intercooler providin
arm-wrenching results on the water. Realizing that boost loss was just
as important as thermal performance, we designed the Power Cooler
with a large, unrestricted core that exhibits minimal pressure loss. Our
cooling element is dramatically more efficient than the stock unit with
exit temperatures averaging 50°F cooler than stock. This delivers cooler,
denser air for increased performance throughout the RPM range. Includes
integrated blow-off valve that improves supercharger reliability and
performance by relieving unwanted pressure during off-throttle operation.
Also reduces supercharger clutch wear and eliminates heat soak in
discharge tube. Kits contain all necessary mounting hardware and
installation instructions. Requires use of RIVA Rear Exhaust Kit (Part
#RS15050) see page 69.

SUPERCHARGER IMPELLER
The heart of any centrifugal supercharger is the impeller. Working closely
with Vortech Engineers, we developed a high performance replacement
impeller that delivers more horsepower and torque throughout the RPM
range. Investment cast from an extremely strong, lightweight proprietary
aluminum and CNC machined to ensure exact tolerances. Sophisticated
blade design is optimized aerodynamically and precision balanced to deliv-
er smooth operation. Installs easily into stock supercharger housing with
no additional modifications required. Includes all necessary mounting
hardware and installation instructions.
NOTE: It will be necessary to upgrade your stock pump impeller to a steep-
er pitch when using our Supercharger Impeller. Sea Doo and RIVA both
strongly recommend the use of premium octane (91+) pump fuel in your
Supercharged watercraft.

HOUSING AND IMPELLER
Our high performance impeller & housing combo deliver a significant
increase in boost pressure and horsepower due through increased impeller
blade surface area and larger interior housing volume. Produces 10.5lbs
of boost at 8,400 RPM when run with our recommended Stage III
components. Impeller features a sophisticated Vortech blade design
that is precision balanced to deliver smooth operation. Housing and
impeller install easily onto stock supercharger base plate with no
additional modifications required. Includes all necessary mounting
hardware and installation instructions.
