Yamaha WaveRunners have changed the face of fuel efficiency across the industry, leading to thousands of dollars of cost savings for our owners. In the case of our VX™ Series – owners will save $1000 each year in fuel costs compared to the next competitive model (based on average annual use). And our clean burning engines offer this efficiency without sacrificing speed. The VX actually has a higher top speed than the next closest model while consuming 2 gallons an hour less. And the SHO Series is the only performance PWC in the industry optimized to run on regular unleaded fuel.

R&D’s C4 Monster Compressor Wheel Kit for all Sea-Doo 215 4 Tec engines will deliver 35-40 “X” type horsepower to the 2004-2008 RXT/RXP Sea-Doo’s to significantly increase overall performance. The R&D Monster Wheel Kit replaces the stock wheels inefficient long inducer, 6 blade design, with a modern low profile, high flow 8 blade w/splitter design with a 2mm larger inducer and increased blade tip height. The R&D C4 Monster Wheel Kit will deliver a solid 11 plus pounds of boost pressure with a 3.5-4 pound per minute airflow gain. The R&D C4 Monster Wheel fits directly into a kit supplied O.E.M. “X” front compressor housing using a .060” compressor case spacer for a “no modifications” bolt on power upgrade kit. The increased inducer size and blade tip height allows more air to flow over the wheel thus producing more pounds of air flow per minute. The C4 Monster will work with the O.E.M. “X”, or aftermarket intercooler kits, and performs well on 91 octane pump gasoline. The benefits are: Boost rated 11/13 P.S.I. (10.5 @ 8000 and 13@8500), Better throttle response, increased horsepower, Increased boost pressure ( 3-4 over stock @ 8200 rpm), Increased airflow (3.5-3.75 pound per minute gain), 35 plus horsepower increase and 3 plus MPH gain, Precision balanced (turbo specs .012-.027 gram inches), Utilizes O.E.M. intercooler and 91 octane pump gas friendly.

R&D’s C2 Monster Compressor Wheel for all Sea-Doo 215 4 Tec engines will deliver “horsepower you can feel” with instant throttle response, improved mid range acceleration, and increased top end performance. The R&D Monster Wheel replaces the stock wheels inefficient long inducer, 6 blade design, with a modern low profile, high flow 8 blade w/splitter design with increased blade tip height. The R&D C2 Monster Wheel will deliver a solid 9pounds of boost pressure with a 2.5 pound per minute airflow gain. The R&D C2 Monster Wheel fits directly into the O.E.M. compressor housing using a kit supplied .040” compressor case spacer for a “no modifications” bolt on and go part. The increased blade tip height allows more air to flow over the wheel thus producing more pounds of air per minute of flow. The C2 Monster works exclusively with the O.E.M. intercooler, and performs well on 91 octane pump gasoline. The benefits are: Boost rated 8.5/10.5 P.S.I. (8.5@8000 and 10.5@8500, Better throttle response, increased horsepower Increased boost pressure ( 2.5-3mph over stock @ 8200 rpm), Increased airflow (2.5 pound per minute gain), 25 plus horsepower increase and 2 plus MPH gain, Precision balanced (turbo specs .012-.027 gram inches), Utilizes O.E.M. intercooler, 91 octane pump gas friendly

The R&D Yamaha SHO Intercooler Temperature Control system was developed to offer an inexpensive complete bolt on kit that will allow the full performance and cooling potential the O.E.M. intercooler has to offer for recreational applications. Intercooler core water temperatures have a range of affect on the supercharged air temperatures that enter into the engine. The Yamaha SHO Intercooler operates on a single low pressure (10 P.S.I.) line of lake temperature water to cool the intercooler. R&D has found that by adding an additional intercooler water in line, and adding an additional water out line and bypass fitting, there will be double the water flow volume at 20 P.S.I. Reduced intercooler core temperatures can add a noticeable increase in low end and midrange power along with reduced detonation. R&D offers a range of machined flow control fittings to allow water volume control tuning for intercooler temperature adjustments for warm lake water and extreme hot air conditions. R&D also offers a pressure relief blowoff valve kit for high water volume flow rates on higher boost Stage 1 and up engine kits. The R&D Kit will allow temperature tuning that will deliver surprising results. Unlock hidden performance and power potential in the OEM stock intercooler or aftermarket intercooler system by reducing intercooler core temperatures.

The R&D High Performance Power Plenum Air Filter Kit was designed and developed exclusively for the new Yamaha SHO supercharged intake system. The R&D filter kit will unleash low-end, mid-range, and peak horsepower trapped in the restrictive stock air box. The exclusive lightweight filter design couples to the OEM supercharger hose and is engineered with a large 6”x10”x6” plenum to deliver massive cubic air volume and improved air speed to the supercharger. Dyno tested and championships proven, Power Plenum Filters generate the maximum airflow and volume. Replacing the O.E.M. air box with the R&D Filter kit offers an economical way to improve performance, looks, and sound at a fraction of the cost of other aftermarket kits. Performs well, sounds good, looks great, saves cash, and will install in minutes. Kit comes complete with all necessary hardware. See picture of filter installed at bottom of page. Pt. # 200-01801
