In terms of R&D I meant adapting some of the RSR components into a steet environment, not engine design. The cost I am sure was significantly lower than designing it from ground up, but developing neww specs for the engine, which a mixture of RS38 components and RSR 40 components with
warranty must have required some development. i thought they wouldn't spend it, or defocus resources from the next version's development. In either case, they nailed it IMHO
