Workshop, engine build and dyno facilities
Developed here, not passed from place to place
Keeping the workshop, engine-building and dyno facilities together means the complete specification can be considered from the start. Installation, diagnostics, calibration and testing can be approached as one joined-up job rather than a collection of unrelated parts.
That matters whether you are refreshing a much-loved road car, planning a responsive fast-road package or developing a high-power build.
