This is the Ultra engine with the R&D Turbo kit that most people talked about during the World Finals without having seen it how it performed in the water According to Chris MacClugage Bill Chapin of R&D and Lee Manvel (the hull builder) have tested the ultra and had good results for an initial test at 10 pounds of boost pressure that showed a top speed of 76mph at 8.350rpm. But this is only a start, since the supercharged edition was showed 76mph with 10 pounds so I think turbo has great potential. Remember the ignition is stock still! MacClugage had said. We present exclusively the R&D Ultra Turbo kit under the Features Section.
