The British company Building The Legend, which is engaged in the restoration of classic Jaguars and the construction of replicas of the Leman XJ13, has developed its own V12 engine, which can be installed on both a road and a racing car. He repeats the engine created by Claude Bailey for the 1960s Jaguar racing program, but completely reinterprets the historical concept to unleash the full potential of the unit.
In mid-1955, a team of Jaguar engineers set about developing a new racing engine for Le Mans. The project was led by former brand designer Claude Bailey. Eight years later, the first prototype “aspirated” V12 5.0 appeared with four upper camshafts – the unit’s capacity was 502 horsepower and 523 Nm of torque.
The XJ13, which was built for the new engine, was not very fast, and besides, it had a tendency to demolish the rear axle and take off at high speed. After unsuccessful tests, the barquette was thrown into the long box, and the V12 engine was adapted for road cars.
The development of Building The Legend is called tera and shows “what could happen” if Bailey’s engine continued to improve. The new two-valve unit provides two options for the working volume: 6.1 and 6.3 liters. Power varies from 355 to 660 horsepower (407–813 Nm of torque); the cut-off is at 8000–8500 rpm. “Atmosphere” is adapted for road and racing cars, and the company indicates that “the use of the motor is limited only by the customer’s imagination”.
The monstrous atmospheric V12 was also previously shown by the Australian Race Cast Engineering. It is a cast iron block of its own design, complemented by components from the General Motors LS series engines. The volume of the unit is 9.5 liters, power – 765 horsepower and 941 Nm of torque.
