Shannon Racing Cars was a British Formula One constructor that made a single World Championship appearance at the 1966 British Grand Prix. Founded by Aiden Jones, a former mechanic to Prince Bira and Prince Chula, together with engineer Paul Emery, the team built just one Formula One chassis, the Shannon SH1.
Although its Formula One career lasted only a single race, the SH1 was an innovative design powered by a rare Coventry Climax Godiva V8 engine before enjoying a second life in Formula Three competition.
Note: Not to be confused with Shannon Racing or the Shannon Racing Team, which was a short-lived motorsport team that was briefly involved with the Forti Formula One team during the 1996 season. It was owned by a parent company known as FinFirst. Both entities were registered in the Republic of Ireland, but funded by Italian backers

Origins
Shannon Racing Cars was established with the ambition of building an independent British Formula One challenger for the new three-litre regulations introduced in 1966.
The project was led by engineer Paul Emery, formerly of Emeryson, who designed and built the team’s only chassis. Aiden Jones oversaw the operation, drawing on his extensive experience as a mechanic working for Prince Bira and Prince Chula during the earlier years of Grand Prix racing.
Rather than using one of the increasingly common customer engines, the team opted for one of the rarest power units in Formula One.
The Shannon SH1
The Shannon SH1 featured a steel monocoque chassis with advanced suspension design for its era. At the front, it employed double wishbones, outboard brakes and an anti-roll bar, while the rear used a compact arrangement of upper and lower radius arms with outboard spring and damper units. One of the more unusual features was the front suspension layout, where the rear section of the upper wishbone acted as a cantilever to operate vertically mounted inboard springs and dampers.
The monocoque extended behind the engine, allowing the gearbox to sit further to the rear and creating an exceptionally compact package. An aluminium monocoque was also constructed during development, although it was never raced.
Power came from the legendary Coventry Climax FPE “Godiva” V8, an engine whose origins stretched back to 1954. Originally developed for the Kieft Formula One project, the engine had never raced after Coventry Climax cancelled the programme due to problems with fuel injection.
Years later, the remaining stock of Godiva components was acquired by Andrew Getley, who allowed Paul Emery to modernise one example for the new three-litre Formula One regulations. Emery enlarged the engine to three litres, converted it to run on pump fuel, and installed a Tecalemit Jackson fuel-injection system. The resulting double overhead camshaft V8 produced approximately 312 bhp during dynamometer testing at Chrysler’s facility in Kew.
Formula One
The Shannon SH1 made its only Formula One World Championship appearance at the 1966 British Grand Prix at Brands Hatch.
Initial testing was carried out by Syd Fox during practice, but overnight modifications were required after the team’s engineers realised the larger three-litre engine consumed more fuel than anticipated. Additional pannier fuel tanks were fitted before qualifying.
Before the race, the team decided to replace Fox with experienced Grand Prix driver Trevor Taylor, who successfully qualified the Shannon for the race.
The team’s Formula One debut proved frustratingly brief. After completing just a single lap, one of the newly installed pannier fuel tanks developed a leak, forcing Taylor to retire and ending Shannon Racing Cars’ only World Championship appearance.
Formula Three
Plans to continue developing the SH1 in Formula One came to an end when a promised sponsorship agreement with a petrol company failed to materialise.
Rather than abandon the chassis, Shannon converted it for Formula Three competition by replacing the Coventry Climax V8 with a one-litre Cosworth MAE engine, initially prepared by Holbay and later by EMC Motorsport. The engine was fitted with twin twin-choke Weber carburettors, allowing the car to compete under Formula Three regulations.
The converted SH1 remained active until 1969, driven by John Wilson and Keith Jupp. Wilson later praised the chassis, recalling that despite competing against designs two or three years newer, the Shannon handled better than many of its rivals.
Legacy
Following its racing career, the Shannon SH1 was preserved rather than dismantled. A later owner reunited the chassis with another Coventry Climax FPE Godiva engine acquired from Gordon Chapman, who had owned many of the surviving Godiva components.
Today, the Shannon SH1 and its rare Climax V8 are believed to form part of a private collection in Austria alongside several Emeryson racing cars, preserving one of Formula One’s most unusual and technically fascinating one-off constructors.
