Following the success of the Antonov Dual Speed Supercharger, we have been approached by many aftermarket tuners to ask if the dual speed can be applied to other supercharger systems - Procharger, Vortech or Magnusson for example.

To meet this demand, Antonov have developed a stand alone dual speed pulley. This can be mounted such that the input pulley is driven from the main front end belt drive and the output pulley then drives the supercharger.
===========================================================

The unit is in test now and it is expected to be available for initial distribution by March 2008.

Development of the dual speed supercharger showed the dramatic benefits a two speed drive gives to a supercharged vehicle. However the cost of developing a complete installation kit is high and there are many existing supercharger installations in the market.

It was therefore clear that a stand alone dual speed pulley would make available the benefits of dual speed supercharging to a much larger market.

Initial development work is underway and the product will be available from April 2008.

Initial applications are expected on applications such as the Mustang - the attached data shows what this can do for the vehicle.
