We have a significant amount of experience in building engines for BMC 'A Series' based Formuila Junior cars. We have a range of parts to build your ideal engine, or if you prefer we offer a comprehensive range of engine building services, why not allow the experts to build your engine?

To monitor the increasing power and develop ever more sophisticated cam and ignition systems, we have our own in-house Dynamometer facilities. A purpose built, fly-by-wire controlled cell, sports a barrage of sensors to provide us with a huge amount of information on your engine’s performance. This Dyno has been called ‘the most sophisticated in classic racing’ and we know that it enables us to give our customers the extra power they seek.
