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 Uprade 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.
RIVA Pump Seal Kit is installed. Location specific molded
inserts are siliconed in to the voids of the OE transom plate and RIVA
Top-Loader Intake Grate significantly reducing cavitation.
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 FZR & FZS. 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.
RIVA Top-Loader Intake Grate & Performance Ride
Plate are installed. Our ride plate and intake grate combo increase top
speed and significantly enhance handling characteristics. Prop spin and
cavitation found with the stock grate is greatly reduced along with the
modified FZ's tendency to drop on its nose when the throttle is let off
at high speeds.
