Parts/Kit Overview

The R&D RXT 260 AS/IS Performer Kit delivers an impressive increase in acceleration and adds up to 8 MPH top speed performance while improving overall handling and stability. The R&D Performer Kit is easy to install and is available at a reasonable retail price! Each part in the Kit can be used individually as a “stand alone” product. The RXP-X with a Performer Kit is sure to be the new recreational “king of the lake”.

  • The R&D R3 ECU Reprogram Service is one of the first performance upgrades that should be done to the new RXT 260. The new 2012 RXT 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 R3 ECU Reprogram produces some serious performance gains through its advanced ignition timing, re-calibrated fuel map, increased rev limit to 8250, removed GPS speed control, eliminated acceleration governor, and raised internal boost limiter to allow maximum boost pressure to be reached. With the 8250 rev limiter, the OEM boost pressure is boosted to 10 full pounds. The R3 ignition timing safely maximizes performance with 91 octane pump gas allowing the Sea-Doo 260 engine to accelerate much quicker out of the hole and pull harder through the mid range with up to 8 mph speed gain.

    R&D R3 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 all out racers who is interested in more performance, the R3 ECU is an absolute “Must Doo” Upgrade. To quote Sea-Doo’s new wave of campaign adds, “It’s just like that”.

  • The R&D RXT 260 AS/IS 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! Also, there is zero speed loss with the R&D Aquavein Grate. In fact, speed improvements of 2.5 -3.5 have been documented by R&D customers in both flat and rough water conditions. The R&D RXT 260 IS/AS Intake grates Race Technology Inspired Wing concept will efficiently load the Impeller/pump at all speed ranges and promote second to no other acceleration performance. The R&D RXT 260 AS/IS Intake Grate has been endurance race tested in the MH300 two years in a row, and finished on the podium each time. Wide open, two years in a row, same grate, same great results!

  • The R&D RXT 260 AS/IS Pro Series Sponson Kit will increase top speed stability in rough water conditions, as well as add increased and improved turning performance. The Pros at R&D have incorporated into the R&D Sponsons a lot of race inspired technology to keep the RXT 260 AS/IS ultra stable at top speed and corner sharp and smooth. The R&D Sponson Kit offers 2-position sponson blade adjustability, which will guarantee this kit to out perform any other 1 up, 2 up, 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.

  • The R&D/Solas 15/22 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 15/22 is custom tuned and tested to work exclusively with the R&D R3 ECU Program. R&D stocks a complete line of Pro Pitch Impellers that are guaranteed to 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 installation of an R&D RXT 260 AS/IS 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 RXT 260 AS/IS 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.
