Stage 1 Performance Overview This kit delivers a significant level of performance (+5mph on U.S. models) through easily installed electronic, air intake and pump components. No internal engine modifications are required. RIVA Performance Power Filter is installed. Power Filter Kit draws cold air from outside your engine compartment delivering awesome performance and eliminating power-robbing heat intake. Air intake is separated from hot engine compartment with rigid thermal bulkhead that installs between engine & fuel tank. Cold air is delivered to engine via large 4” smooth-bore ducting that is attached to supercharger with unique velocity stack and sturdy billet clamps. RIVA Speed Control Override Module is installed. Module removes the restrictive GPS controlled speed limits (67mph US/72mph International) on Sea-Doo iControl models allowing top speed to exceed factory settings. This is the "gateway part"" necessary for all modifications that utilize stock ECU. RIVA Catch Can/Engine Breather Upgrade Kit is installed. Easy to install catch can/oil breather eliminates power-robbing crankcase fumes and oil vapor 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. 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 1 package using a pitch block to ensure accuracy. Billet impeller cone is included. NOTE: Sea•Doo and RIVA both strongly recommend the use of premium octane (91+) pump fuel in your craft. NOTE: RIVA Performance Kits intended for competition use only."

This is the new project that R&D has been working on to. It is a turbo kit for the FZR engine that features special brackets, engine cases cover, oil pump, inputs for MoTeC sensors etc. The famous American company has placed the turbo in the most efficient place, where no one has put it until now. We expect to hear from the company in the near future about the first outcome from the tests. There is one thing for sure, that R&D is not sleeping…

Two days before the Mark Hahn 300 race we worked along with R&D’s personnel and we tested exclusively the new Stage 1 kit that was developed for the VXR and was initially put to Aero Sutan Aswar Yamaha in order to race it. The fact that Aero smoked a lot of Supercharged and Turbocharged crafts and managed to finish seventh overall and first in the Natural Aspirated class proves a lot. Read the complete test and product report under the Race Tests section.

Japanese company Sato Engineering Speedmagic made its magic ones again. Last year he had succeeded on putting an STX-15F engine inside a Kawasaki X-2. This year the company challenges Kawasaki ones again by presenting its latest project a four-stroke SX-R, in other words an SX-R equipped with a 15F motor. Isn’t that cool? The pictured was found at Tech514 blog spot.

The new “drop-in” R&D C8 Monster Compressor Wheel and Exducer Seal Plate Kit installs directly into the OEM supercharger without any modification. The new C8 delivers “horsepower you can feel” with instant throttle response, aggressively improved low and mid range acceleration, and intensified top end performance. The new C8 features a light weight, high flow, 8 blade design with 8 supporting splitter veins and an increased exducer compression height over stock. R&D’s larger exducer height and aggressive blade design is the key to improving CFM airflow volume throughout the RPM range. The increased exducer height dimension increases the size of the supercharger by enhancing air pumping volume and efficiency. The C8 out performs any OEM sized compressor wheel in its boost pressure classification. After all, its airflow volume gains that increase horsepower. The R&D Monster Wheel Kit produces 18 plus pounds of boost pressure @ 8700-8900 rpm, 16+ @ 8500-8600 rpm. The new drop-in R&D C8 also offers superior off throttle surge over other 16-18 pound boost wheels. Less surge increases supercharger clutch reliability. The new R&D C8 series compressor wheels offer the highest levels of airflow and horsepower gains available for the 1.8L Yamaha engine. A properly tuned C8 set up (with supporting modifications) can produce well over 325+ horsepower. In addition, the rotating group of the new C8 Monster Wheel combined with the R&D Billet Supercharger Shaft is the undisputed Light Weight Champ, no other rotating group on the market is lighter or more powerful. Less is More: In sum, the R&D C8 Monster Wheel and Shaft weighs less, has far less surge over competitors’ wheel kits, rockets to 80 in less seconds and carves through corners in less time than any other wheel and shaft on the planet. Hit the throttle, hang on and discover the astounding sensation that less IS more …much, much more. R&D facts: Aggressive throttle response, increased horsepower, Increased boost pressure ( 12 P.S.I. over stock @ 8800 rpm), Increased airflow volume ( 14-15 pound per minute gain), 100+ horsepower increase (with R&D R3 ECU), 350+ horsepower w/supporting parts, Precision balanced (turbo specs .012-.027 gram inches), Utilizes O.E.M. Reprogrammed R3 ECU ignition system, Utilizes O.E.M. fuel injectors w/R&D RRFPR, R3, and Powershot, 91 octane pump gas friendly with R3 ECU, Less weight and surge, Easy installation. C8 Modification Requirements: R&D High Performance Pro Series Intercooler Kit w/R&D Greddy BOV, R&D Rising Rate Fuel Pressure Regulator Kit, R&D R3 ECU upgrade to allow 8500-8850 RPM, R&D Powershot, R&D Engine/intercooler Cooling Kit, R&D Twin Prop Boost rating; 12 @ 7800, 15/16 @ 8400-8500, 17 @ 8700-8800, 18 @ 9200-9500). NOTE: The C8 Monster Wheel will work best in sea level to 2000 ft. elevations, or in ambient air temperatures between 60 and 100 degrees. NOTE: The C5 Monster Wheel Kit will require serious impellor upgrades; call R&D for the latest in impellor suggestions. Contact R&D for intercooler suggestions, and impellor pitch/nozzle combination that will be best for your performance level or application. R&D stocks the largest selection of custom impellors for the SHO/FZ/FZR. Available from R&D, Pt. # 612-25008…Retail $649.95

We test the new Kawasaki 300X at Body Beach and we learn crucial information for its design and features by Graig Warner and Minoru Kanamori. Top speed was rated at 67mph stock, and 72mph on its unrestricted version. We rode both, read all about it under the Tests section.

We tested the Yamaha VXR three days before Mark Hahn 300 race and we saw R&D preparing it especially for this race, which won its class. Read all about the new Yamaha under the Tests section. How it performs, how fast it is and how simple to take care of. Soon we will present the test of the R&D’s Stage 1 kit too.
