  • The Mighty Demon Carburetor has billet aluminum metering blocks, billet aluminum baseplates, large capacity fuel bowls with patented sight glasses, and patented streamlined air entries. Some of these features are found only on modified carburetors that cost much more, and several are available only on Demon Carburetors. These innovative ideas allow the new Mighty Demons to produce more power and achieve higher levels of performance than conventional designs. All Mighty Demon Carburetors have a "General Competition" tune-up but can be easily modified using BG Fuel Systems carburetor service and tuning parts.

    Mighty Demon Blow-Thru Carburetors operate with up to 18 psi of boost and are available in 650, 750, and 850 cfm. They increase the vacuum signal to the carburetor under boost and enrich calibration. Equipped with annular boost venturi, large screw-in power valve channel restrictors in the metering blocks, and 0.130" needle-and-seat valves in the fuel bowls. The bowls also contain non-collapsible solid nitrophyl floats, unlike their brass counterparts. Air bleeds are appropriately sized. These new calibrations result in a flat fuel curve. Even at higher RPM, the main circuits sustain constant BSFC (Brake Specific Fuel Consumption) values and air-fuel ratios. The idle circuits, which often carry the responsibility for part-throttle cruising, will offer fine non-boosted drivability.

    For high-output street engines and race engines, the Mighty Demon delivers the best performance value for the dollar!
