The most revealing signs of a carburetor company’s standing are its reputation for innovation, its record of success, and how easy it is to deal with. When the Demon range of four-barrel modular carburetors first burst onto the scene in the late 1990’s, it acquired a meteoric reputation for innovation. Immediately noticeable was its uniquely attractive appearance with beautifully contoured air entries and shapely fuel bowls. This coupled with its vast array of ground-breaking features set it apart. To eradicate internal porosity Demon introduced billet metering blocks and base plates. To eliminate impediments to the air flow Demon initiated ridge-free concentric venturii. To overcome the dangers of fuel contacting hot exhausts during float-level checks, Demon instigated large capacity fuel bowls with sight glasses. To nourish the ambitions of adventurous tuners, Demon invented interchangeable venturii, idle-feed restrictors, and air bleeds. Of its type, these were and remain today the most potent carburetors ever devised.
