RIVA/Vortech 'GEN2' Supercharger Impeller is installed. This high performance replacement impeller delivers more horsepower and torque throughout the entire RPM range. Investment cast from extremely strong, lightweight proprietary aluminum and CNC machined to ensure exact tolerances. Sophisticated blade design is optimized aerodynamically & precision balanced to provide smooth operation. Installs easily into stock supercharger housing with no additional modifications required.

RIVA 'GEN-3' Power Cooler Kit is installed replacing original intercooler system. Power Cooler is dramatically more efficient than original intercooler system delivering an increase of 15 peak horsepower with exit temperatures averaging 50°F cooler than stock. Features large, unrestricted core that exhibits minimal pressure loss compared to stock intercooler. Includes integrated blow-off valve mount for improved reliability and performance. Performance Blow-Off Valve (sold separately) relieves unwanted pressure during off-throttle operation reducing supercharger clutch wear and eliminating heat soak in discharge tube.

RIVA Rear Exhaust Kit is installed. Kit allows removal of restrictive sound suppression system located between waterbox and hull exit. Improves engine performance by reducing back pressure & restriction. Includes custom molded exhaust tube and billet through hull exhaust outlet. It is necessary to install Rear Exhaust Kit to accommodate RIVA Power Cooler Kit.

RIVA Top-Loader Intakte Grate is installed. Unique wing design eliminates prop spin and cavitation while delivering improved handling and top-speed.

Solas 'R'-Series Concord Impeller is a special performance impeller offered exclusively by RIVA and RIVA authorized dealers. This impeller is specifically pitched for our Stage 2 RXP package using a pitch block to ensure accuracy. Billet impeller cone is included.

RIVA Pump Wedge is installed between pump stator and output nozzle. 2° wedge trims up your pump nozzle raising the bow of your craft for less drag substantially improving top-speed. Features a double-sided lip to retain silicone sealant and prevent cavitation.

RIVA Pro-Series Sponson Kit is installed. Our sponsons dramatically improve the handling of the RXP with superior blade & backing plate design. Sponson depth is adjustable to accommodate riding style.

RIVA O.P.A.S. Performance Block-off Kit is installed. Removal of O.P.A.S. System improves handling characteristics for competition use. Removal of O.P.A.S. System is necessary to accommodate RIVA Rear Exhaust Kit. RIVA Racing does not recommend the removal of O.P.A.S. system for recreational use.

NOTE: No modification of fuel delivery system required. Our testing has shown that the original ECU automatically increases the amount of fuel as a response to the increase in manifold boost pressure with our Stage 2 Kit. Original air/fuel ratio is maintained throughout the entire RPM rpm. Optional upgrade to our Pro-Series ECU, Fuel Injector Kit and Valve Train Upgrade Kit will increase acceleration & top speed. Use of premium octane (91+) pump fuel is required.
