Atspeed have over 30 years experience with carburettor tuning, covering almost all types of carburettor available, including vintage and historic carburettors. We are recognised Weber calibration engineers and an Official Weber Carburettor Dealer And Weber Tuning Specialists – Recommended By Webcon themselves.

We also tune SU, Dellorto, Pierburg, Solex, Stromberg,  Holley, Edelbrock and motorcycle carburettors.

We keep a huge stock of Weber jets, and also stock Holley / Edelbrock jets/springs for American vehicles. SU carburettor needles are also stocked or bespoke made for your car. We keep a wide selection of calibration components for most type of carburettor, including gaskets, chokes and jets.

The majority of our tuning work is carburettor set ups on classic road vehicles, and also historic race and rally cars. As well as private owners and enthusiasts, we regularly carry out carburettor calibration work for high end classic car restorers, and celebritiy car collectors.

We offer carburettor tuning for motorsport purposes, as well as road cars, including turbocharged vehicles. We have a great expertise in the world of short circuit oval racing, and grasstrack racing, where we can apply advanced techniques learned through years of experience to give you the engine control and throttle response you require to have the edge over your competitors.

The “TAT” software comes into its own when tuning carburettors, and takes away the “guess work” associated with older technology. Now, with the graph overlay feature, and modern data logging, you can see the difference one jet change has made to the fuelling and corresponding engine power and torque.
