This modification delivers the maximum level of performance
(+3~4mph) through easily installed air intake, exhaust, and pump
enhancements. No internal engine modifications are required.
RIVA Performance Power Filter is installed. Kit replaces
restrictive factory intake system delivering improved throttle response
and top-speed.
RIVA Intake Manifold Upgrade Kit is installed. Precision
tapered billet sleeve directly replaces restrictive mesh element in
intake manifold enabling engine to produce more horsepower through
increased air flow and boost pressure (+1lb).
RIVA Free Flow Exhaust Kit is installed. Kit replaces
restrictive sound suppression system located between water box and hull
exit reducing backpressure and engine operating temperatures.
Dramatically reduce cavitation and prop spin with the
R&D Pump Seal Kits. Location specific, molded inserts fill the
voids in OEM pump inlet shoe that bleed air into pump causing
cavitation. Recommended for modified crafts using the R&D FX
intake grate.
RIVA/Solas 'R'-Series DynaFly Impeller is a special
performance impeller offered exclusively by RIVA and RIVA authorized
dealers. Built by Solas, this impeller delivers the ultimate in
performance for the FX-SHO. Inner hub is machined allowing impeller to
mount closer to vein housing for reduced cavitation and more top speed.
Impeller blades are digitally calibrated to RIVA's uniform pitch
specifications. Impellers are then dynamically spin-balanced at high
RPM. A precision factory blueprinting process is performed far
exceeding any "prop shop" services available. Includes Billet Impeller
Cone for maximum performance and durability.
R&D Aquavein intake grate improves hook up and
handling in rough conditions. Center wing eliminates prop spin and
cavitation found with the stock grate along with the SHO?s tendency to
drop on its nose when the throttle is let off at high speeds.
