George Mangoletsi started his design and inventing career in 1926. By 1929 he patented a Desmodromic valve gear system, some features were used in the 1954 Mercedes Benz W196 grand prix cars.
He then developed gas carburettor systems with, rooftop, top gas-bags, which were used during wartime as official Ministry supply for public transport, buses and commercial vehicles, if you done know what these look like just have a look at some episodes of 'DADS ARMY'.
In the 1950s the experience gained from working with gas carburation led to the design and patenting of the GM Manifold Modifier. This simple device, fitted between the carburettor and the manifold, greatly improved the distribution by atomising the fuel more efficiently, and keeping the unmixed petrol from attaching to the walls of the manifold. The modifier gave much smoother running, more torque and better fuel consumption, and was found to be the only such device that worked according to motoring magazines of the time.
By the mid-1950s the engine tuning business was started with the introduction of the Mangoletsi re-ported and polished range of manifold for production cars, to be used with standard carburettors. The GM Manifold Modifier was machined into the manifold at the intake and outlet ports. Standard manifold design was so poor in those days that significant gains were obtained in performance, drivability and economy, from just fitting these manifolds. When used in conjunction with gas-flowed high-compression cylinder heads, further substantial improvements in performance were achieved.
In1960 George’s son, John, joined the company. With the advent of Weber twin-choke high performance carburettors, the opportunity arose to develop GT versions of standard production cars, which heralded the start of the Mangoletsi range of high performance cast aluminium inlet manifolds – still the market leader after 50 years of experience, innovative design and development.
Mangoletsi exhibited at the 2nd Racing Car Show in 1960 – now the only tuning company from that show in existence.
With the rise in popularity of restoring and tuning older classic cars, the demand for inlet manifolds for older cars has increased. In response Mangoletsi have produced the new and updated range of manifolds.
I expect the main reason for their success was in having there own foundary so they could control the quality of the products, so much so that they even produced manifolds for the competition in the 1960's these included other well-known tuning equipment manufacturers, such as John Sprinzel, Jack Brabham, Broadspeed, Taurus & Janspeed.
It's the ability to adapt to the changing market that has kept Mangoletsi in business to this day therefore becoming the oldest company in the tuning world.
