Parts/Kit Overview

The R&D RXP-X 260 Pro Stock Racing Kit will deliver exactly what is needed to be a podium contender and class winner in Pro Stock Class Competition. The R&D Kit is quick off the line with an impressive increase in low end acceleration, mid range pulling power, and increased top speed up to 10 mph. The kit also offers superior overall handling, fantastic pump hook up, and rocket fast straight line stability. The R&D Pro Stock Kit maintains great reliability and is race budget friendly using High Grade 100 octane (Sunoco 100 unleaded) “pump race gas”. The R&D Pro Stock Kit is easy to install and is available at a reasonable price. When you shop and compare price to performance, it doesn’t take long to realize that the R&D Kit is a very powerful value!

  • The R&D ECU Reprogram Service is one of the first performance upgrades that should be done to the new RXP-X 260. The new RXP-X ECU has an internal acceleration governor and top speed governor that’s GPS controlled to only allow 67-68 mph. The GPS speed governor controls the throttle plate to modulate and restrict airflow into the intake plenum. The throttle plate modulation controls and limits the boost pressure to 7 pounds. The R&D ECU Service is a vital and necessary key to unlocking and adding performance to the new Sea-Doo 260 engine platform. Whether you are a recreational enthusiasts or an off shore racer who is interested in more performance, the R&D ECU is an absolute “Must Doo” Upgrade.
    The R&D R-PSR (Pro Stock Racing) ECU Reprogram produces some great performance gains through its aggressively advanced ignition timing, re-calibrated fuel map, increased rev limit to 8750, removed GPS speed control, eliminated acceleration governor (starts in sport mode), and eliminated boost limiter to allow maximum boost pressure to be reached. With the 8750 rev limiter and removal of the GPS control, the O.E.M. boost pressure (7 pounds) is boosted up to 10 plus pounds. The R-PSR ignition timing safely maximizes performance with 100 octane race gas allowing the Sea-Doo 260 engine to accelerate much quicker out of the hole and pull harder through the mid range with significant speed gains.

  • The R&D/Solas 13/18 or 14/19 Pro Pitch Racing Impeller is a custom Pro Pitch Tuned impeller that meets the performance demands of the R&D Pro Stock Kit. In fact, R&D tuned Solas Impellors found their way to several podium finishes in Stock Classes at the 2012 World Finals. The R&D/Solas is custom tuned and tested to work exclusively with the R&D Pro Stock Racing Spec ECU Program. R&D stocks a complete line of Pro Pitch Impellers that will out perform “out of the box” aftermarket impellers. Performance gains include reduced cavitation, increased acceleration and improved top speed. Call R&D for other custom impellor pitch options that will work with your choice of ECU rev limit settings, or riding environment and conditions.

  • The R&D RXP-X 260 Aquavein Intake Grate kit will keep your Sea-Doo RXP-X’s pump loaded, hooked up, and off the rev limiter to improve handling and top speed performance. Improved straight-line stability and smoother, tighter turning capabilities will be noticed instantly. Top speed improvements of 2.5 -3.5 have been documented by R&D customers in both flat and rough water conditions. The R&D RXP-X Intake Grate’s Race Technology Inspired Wing concept will efficiently load the impellor/pump at all speed ranges to promote maximum acceleration performance.

  • The R&D RXP-X Pro Series Sponson Kit will increase top speed stability in rough water conditions, as well as add increased and improved turning performance. The Sea-Doo RXP-X 260 sponson has a unique stock feature that is tabbed as a “decelerator fin”. The decelerator fin does a good job of keeping the RXP-X stable at cruising speeds with a stock engine package. However, who needs a decelerator fin when you want to accelerate? The Pros at R&D have incorporated into the R&D Sponson lots of race inspired technology to keep the RXP-X 260 ultra stable at top speed, corner sharp and smooth, and actually increase acceleration from zero to 30 mph by leaving the “decelerator fin” out of the design. R&D has done all this without loosing any of the cool inside lean handling performance the RXP-X 260 is admired for. The R&D Sponson Kit offers 2-position sponson blade adjustability, which will guarantee this kit to out perform any other 1, 2, or 3 up. The R&D Pro Series Sponson Kit offers a smoother more predictable ride with much better low and high speed turning capabilities. Track tested and race proven! Kit comes complete with all hardware and instructions.

  • The R&D RXP-X Pro Series 4” Air Filter Kit was designed and developed exclusively for the new Sea-Doo RXP-X. The R&D 4” filter kit will unleash restricted low-end, mid-range and peak horsepower by entirely removing the O.E.M. air filtration system and replacing it. The R&D Kit includes a huge 4” “ snap on” rubber velocity stack that allows large 4” Kanaflex flexible hose to be attached to the supercharger and cleanly run to the front of the hull to capture cooler air. The R&D Pro Series 4” Filter Kit has ZERO restriction to the supercharger which means quicker acceleration and more power.

  • The R&D Thermostat/Intercooler/Engine Cooling Kit is one stop shopping to solve several big issues with the O.E.M. cooling system. Engine temperatures on a RXP 260 engine with performance upgrades can reach 190-195 degrees with the stock cooling system. The R&D Kit changes out the stock thermostat for a new cooler 160 degree thermostat. The R&D Kit also separates and re-routes the “intercooler out” and “engine out” water lines to allow less restriction and more water to flow through both the engines exhaust system and the intercooler which will promote cooler exhaust temperatures as well as reduce intake air temperatures. The R&D Kit also includes a two new 1/2 inch water bypass fittings for the intercooler in and out lines, one to be used with the kit included high pressure relief valve, and one for the intercooler water out. The R&D “high pressure” relief valve will protect the intercooler from being broken due to high water pressure spikes. Cooler engine temperatures, cooler intake air temperatures, and cooler exhaust temperatures all add up to a noticeable RPM and top speed gain.
    R&D High Performance Titanium Retainers Kits are a must add kit where engine RPM frequencies are sustained over 8350 on Sea-Doo engines when used in aggressive water conditions where engine over rev situations elevated . The R&D Titanium Retainers are 500 grams lighter than O.E.M. retainers and considerably stronger. R&D Retainers are designed to properly preload the O.E.M. spring slightly to raise seat and full lift tension which will increase valve control and help to reduce valve float.

  • R&D High Performance Fuel Pressure Regulator Kit allows precision fuel pressure adjustments or changes to be made quickly and easily to accommodate perfect engine tuning and achieve spot on AFR calibrations. The R&D Regulator Kit arrives completely assembled and ready to plug and play. R&D “QUICK INSTALL” directions and pre-assembled regulator make this regulator kit an easy 45 minute start to finish install!

NOTE: R&D recommends the installation of an R&D RXP-X Surge Protection Kit offered, which will substantially reduce wear and tear on the O.E.M. supercharger clutch assembly. Automobiles with Turbo Chargers or Supercharges generally always include surge protection valves to protect the supercharger from harm full compressor surge. The R&D RXP-X Surge Protection Kit offered is Part # 613-95258.

NOTE: The R&D RXP 260-X Pro Stock Race kit development, tachometer, and top speed information posted was gathered after an initial 5-mile warm-up to stabilize engine temperatures. All testing was performed exclusively with Sunoco 100 octane pump gasoline at 500 feet above sea level. Ambient air temperature during testing in March was between 75 and 85 degrees. These test results may change as we continue to gather data, and monitor O.E.M. stock boat speed averages, and production impeller consistencies. The information posted in the R&D Stage 1 Kit are averages. In many cases we hear of feedback from Sea-Doo owners with performer kit packages reporting of higher speeds than posted.
