FX-SVHO Stage 3 Kit
Note: All testing performed with 1/3 tank of fuel, trim in neutral, sea level elevation, air temp 80-degrees F.
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 Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.
RIVA F2 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 19psi @ 8,500rpm.
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 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 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 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 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 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 Valve Train Upgrade Kit is installed. Titanium valve retainers and heavy-duty valve springs increase reliability of modified engine by reducing the possibility of valve float at high RPM. To ease installation of Valve Train Upgrade Kit we offer a unique Valve Compression Tool that allows installation without removal of cylinder head saving you time and money.
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 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.
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 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 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.
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.
FOR COMPETITION USE ONLY. PRODUCT NOT FOR USE ON POLLUTION CONTROLLED VEHICLES.
These are additional performance upgrade parts that can be purchased individually to improve the performance kit.
