FX-SVHO Stage 3 Kit

This kit delivers a significant level of performance (+17mph) through easy to install, electronic, engine, exhaust, and pump enhancements. Requires use of fresh premium octane pump fuel (91~93).

RIVA MaptunerX Yamaha Bundle is utilized to reflash original ECU. MaptunerX provides ability to quickly and easily load performance tunes directly into your stock ECU eliminating downtime that results from shipping for programming. Performance Tunes are calibrated to provide optimum fuel delivery, ignition timing and rev limit to compliment RIVA Racing Performance Kits. OEM dash display, engine diagnostics & engine safety functions are retained. MaptunerX features a full color, touch screen display, ability to restore stock tune settings and access to RIVA's complete tuning library and technical support.

RIVA Pro-Series 1,000cc Fuel Injector Kit is installed. High impedance fuel injectors deliver additional fuel to modified engines required for high boost applications.

RIVA High Flow Billet Fuel Rail is installed. Large, precision machined body directly replaces restrictive factory fuel rail (plastic on `13 & newer models) for improved fuel delivery. Provides increased flow capabilities essential for supporting highly modified engines. Includes fittings for flow-through fuel routing to eliminate injector supply fluctuation and keep fuel cooler.

RIVA 'R3' Supercharger Impeller is installed. Designed to deliver more horsepower and torque throughout the RPM range resulting in excellent acceleration and top speed. Precision machined from billet aluminum to ensure exact tolerances and anodized to prevent corrosion. Installs easily into stock supercharger housing with no additional modifications required. Produces 20psi @ 9,000rpm.

RIVA Supercharger Shaft Upgrade Kit is installed. Kit features a hydraulic shaft stabilization bearing that limits shaft deflection and wear. Bearing stabilizes end of supercharger shaft via high pressure oil film dramatically increasing the stability of the system. Hydraulic end bearing and one-piece shaft bearing are fed by a through-shaft oiling system providing superior lubrication. Kit is a direct replacement for OEM parts and requires no additional modifications for use.

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

RIVA Engine Breather Upgrade Kit is installed. 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.

RIVA 'GEN-3' Power Cooler Kit is installed. Power Cooler is dramatically more efficient than original intercooler system delivering an increase of 20 peak horsepower. Features integrated TiAL 50mm Blow-off Valve that relieves boost pressure during off-throttle operation reducing supercharger clutch wear and eliminating heat soak in discharge tube.

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 3-Bar Map Sensor Kit is installed. High quality 3 Bar MAP Sensor is critical to provide accurate pressure information to your aftermarket ECU to ensure proper air/fuel mixture and data logging. Mounts directly in place of OEM sensor with stainless bracket and plugs directly into OEM wiring harness.

RIVA Valve Retainer Upgrade Kit is installed. Kit increases the reliability of your engine by reducing the possibility of valve float at high rpm.

RIVA Pro-Series Water Box is installed. Developed on a flow bench to deliver increased horsepower and performance by reducing exhaust restriction and back pressure. High-strength aluminum construction & precision welds will survive backfires & overheating.

RIVA Rear Exhaust Kit is installed. Kit replaces restrictive sound suppression system located between water box and hull exit reducing backpressure and engine operating temperatures. Mandrel bent Aluminum Exhaust Tube couples water box to Billet Rear Exhaust Outlet for added reliability, performance and serious cool factor.

Solas Concord Impeller is installed. New design incorporates a large blade area and superior hub design that deliver increased acceleration and top speed. Billet nose cone included.

RIVA Pump Seal Kit Dramatically reduce cavitation and prop spin with our easy to install 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 craft using aftermarket intake grates. Includes detailed installation instructions.

RIVA Top-Loader Intake Grate is installed. Prop spin and cavitation found with the stock grate is greatly reduced along with the modified FX's tendency to drop on its nose when the throttle is let off at high speeds.

FOR COMPETITION USE ONLY. KIT NOT FOR USE ON POLLUTION CONTROLLED VEHICLES.
