The R&D Adjustable Boost Control Valve replaces the unreliable OEM Plastic boost control valve that quite often fails to hold consistent factory recommended boost pressure settings. A leaking and inconsistent boost oem control valve (on ther left) will cause a 10-30 horsepower loss in performance. The all aluminum constructed High Performance R&D Adjustable Valve offers perfect sealing and precise adjustment for consistent boost pressure control. The valve comes factory preset for 16 pounds boost and is adjustable up to 22 pounds. The valve mounts directly to the OEM location with a billet aluminum adaptor that offers boss locations that can be used to install a boost gauge. For those with a reprogrammed R&D ECU, this is a must have upgrade to allow the ECU to perform to full potential. Kit includes all gaskets, hardware and installation instructions. Part Number Pt. # 611-25210

This year many race teams used a rotating trailer in order to minimize their time of stay during their pit stop. One of them was Klippestein’s Canadian Team. Mike designed and fabricated it on his own and worked awesome during the race. Indonesian Team of Aswar was using a similar trailer too.

This is the most reliable way to go from 42mph to 60mph on a 60hp Spark. We have tested exclusively the R&D's Sea-Doo in Lake Havasu City. Read all about it in the story published in the Tests section.
