Parts/Kit Overview

The R&D RXP-X 260 Performer Kit delivers an impressive increase in acceleration and adds up to 5 MPH top speed performance gain while improving overall handling, pump hookup, and straight line stability. The R&D Performer Kit maintains the integrity of “Stock Reliability” by keeping RPM’s low and it’s pump gas friendly. The R&D Performer Kit is very easy to install and is available at a reasonable retail price. Most parts in the Performer Kit can be used individually or as a “stand alone” product with the exception of the R&D Boost Box. The R&D Boost Box will unlock an additional 3 pounds of boost, therefore, a taller Impeller pitch over stock must be used. The RXP-X 260 with a R&D Performer Kit installed is sure satisfy your need for speed.

  • The R&D Boost Box 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 Boost Box allows maximum boost pressure (10 PSI) to be reached by overriding the O.E.M. internal GPS speed control. With a 3 pounds increase in boost pressure over stock settings, allows the Sea-Doo 260 engine to accelerate better, pull harder in the upper mid range and top end with up to 5 mph speed gain. The R&D Boost Box 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 offshore racers who is interested in more performance, the Boost Box is an absolute “Must Doo” Upgrade.

  • The R&D RXP-X 260 Aquavein Intake Grate 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 to 3.5 MPH 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 Impeller/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 installs in less than 10 minutes with basic tools and comes complete with all hardware and instructions.

  • The R&D RXP-X High Performance Air Filter Kit was designed and developed exclusively for the new Sea-Doo RXP-X. The R&D filter kit will unleash restricted low-end, mid-range and peak horsepower trapped in the OEM air filtration system. The new R&D Cool Air Filter Kit installs at the front of the hull above the gas tank and replaces the restrictive OEM air box. Replacing the OEM air box with the R&D Filter offers a very economical way to improve airflow CFM and overall performance. Sounds good, looks great, saves cash and will install in minutes.

  • The R&D/Solas 14/21 Pro Pitch Impeller is a custom Pro Pitch Tuned impeller that meets the performance demands of the R&D Performer Kit. The R&D/Solas 14/21 is custom tuned and tested to work exclusively with the R&D Boost Box, R1, R2, and R3 ECU Programs. 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 impeller pitch options that will work with your choice of ECU rev limit settings, or riding environment and conditions. NOTE: R&D Recommends the 14/21 Impeller for 90-110 degree weather conditions, and the 14/22 impeller for 60-85 degree weather conditions.

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 Performer 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 Chevron 91 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 Performer Kit are averages. In many cases we hear of feedback from Sea-Doo owners with performer kit packages reporting of higher speeds than posted..
