Weber Carburetors

When it comes to feeding your Porsche 911 engine or motor fuel and air, the three barrel Webers are the best carburetors in the world. They where made in Italy by a company started by Eldorido Weber.

The original three barrel Weber was fitted to a V-6 Lancia Italian sports car in the 1960’s. Later it was used on the first Porsche 1967 ‘S" model, also four triple barrel Webers where used on the Ferrari " Boxer’s " flat 12 cylinder of the early 1980’s.

 The reasons Porsche Webers are so superior to other carburetors are the following:

• Designed as a high performance carburetor in the beginning , then modify a completely stock carburetor.

• Built to very close tolerance and craftsmanship.

• Total adjustability of five areas of operation through changeability of parts. (Example: ventuires can be changed, as for other carburetors 95% can not be changed.)

• Vast amounts of individual parts are readily available (Example: Zenith’s venturies are changeable, but only two sizes available Webers there are 10 or more different sizes)

• Tune ability, with one carburetor throat to each cylinder you can adjust air and fuel to each cylinder need. Example; when you see a four barrel carburetor on a V-8 the carburetor basically dumps its mixture in a box ( manifold ) and cylinders further away from the center of the carburetor, receives less then the closer ones. This is why you hear these engines idling so very roughly when they have high performance camshafts.
