Description

This Stage 2 Engine Kit produces 275 horsepower @ 8,300rpm utilizing our Athena ECU and stock fuel injectors. Kit delivers major acceleration and top speed and runs reliably on 91~93 octane pump fuel. Installs easily and requires no internal engine modifications.


RIVA Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.


RIVA B1 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. Produces 13.5psi of boost in our Stage 2 Engine Kit.


RIVA 'GEN-2' Power Cooler Kit is installed. Power Cooler is dramatically more efficient than original intercooler system delivering an increase of 20 peak horsepower with exit temperatures averaging 60°F cooler than stock. Features large, unrestricted core that exhibits minimal pressure loss compared to stock intercooler and integrated blow-off valve mount that will accept recommended RIVA/HKS Blow-Off Valve (sold separately). Blow-off Valve relieves unwanted pressure during off-throttle operation reducing supercharger clutch wear and eliminating heat soak in discharge tube

.
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 Fuel Pressure Regulator Kit are installed. Kit provides increased fuel pressure necessary to compliment RIVA Boost Clamp. Set at an optimal static 65psi non-rising rate for our Stage 2 Engine Kit, the unit can be precisely adjusted to match the needs of your riding conditions. Plugs directly into original fuel system with OEM connectors and features a large 3/8" fuel return line that is routed through supplied rubber fuel tank cap. Includes integrated liquid-filled pressure gauge and billet Fuel Pressure Regulator Block-Off necessary for removal of stock fuel pressure regulator in fuel tank.


RIVA/Athena Pro-Series ECU are installed. Our racing ECU is able to match the increased performance needs of modified engines. Base Maps are calibrated to provide the optimum fuel delivery, timing and rev limit to compliment Stage 3 modifications. OEM dash display, engine diagnostic & engine safety functions are retained. Includes input for optional Lambda Sensor Kit for data logging air/fuel ratios & tuning functions. Plugs into wiring harness via RIVA Power Connector and mounts directly in place of stock ECU.

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 Engine Cooling Upgrade Kit is installed. Kit delivers dramatically improved cooling efficiency to engine and oil cooler for increased reliability & performance. Greatly enhances water flow & pressure by replacing restrictive OEM water fittings with high-flow billet fittings and superior routing.


RIVA/Solas Engine Breather Upgrade Kit is installed. Kit eliminates power-robbing crankcase emissions from your engine's air intake. Increases horsepower by removing the engine's requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing the oil sludge coating that lowers thermal efficiency.


NOTE: RIVA Performance Kits intended for competition use only.
