SU Carburettor Tuning and Rebuild
The Jaguar XK engine is, of course, synonymous with the venerable and highly efficient SU Carburettor. They were the standard production carburettor favoured by Jaguar from 1948 to the late 1970s (apart from a brief and unhappy flirtation with Stromberg). Weber 45 DCOEs are also frequently used in competition to obtain extra performance.
The Jaguar E-Type – in both 3.8 and 4.2 Litre forms – is forever associated with its impressive line-up of no less than Three SU Carburettors, visually stunning and delivering outstanding performance. SUs are wonderful for both Road and Track. Intimate knowledge is needed however to extract the greatest benefit.
