Mighty Demon

CNC-machined metering blocks from billet aluminum prevent porosity and variations in the metering circuits

Traditional casting methods can produce unwanted ridge lines which obstruct airflow.

Demon carburetors employ a new die-casting technology, which provides the most accurate, repeatable method of producing concentric venturii without misalignment or shift.

New Idle-Eze™ Idle Speed Tuning System. Fine-tunes your idle speed by precisely metering additional air into the intake. Allows smoother transition from off-idle, avoiding potential for stumble.

Valve is easily accessed with a screwdriver throught the air cleaner stud hole. Can be fine-tuned after the throttle shaft position has been set.

The new Mighty Demon™ is perhaps the best value for the dollar in the carburetor market today.

It is available in a full range of sizes and directly replaces Holley® HP models. It features billet-aluminum metering blocks, billet aluminum baseplates, large capacity fuel bowls complete with patented sight glasses and patented, streamlined air entries. Some of these features are found only on modified carburetors costing 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 come with a "General Competition" tuneup, but can be easily modified using BG Fuel Systems carburetor service and tuning parts (see pages 64-74 in this catalog).

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

Patent #6286817	Demon float bowls use special 9/16" x 24 TPI inlet fittings. These are available in standard, filtered or swiveled styles and in sizes of #6 or #8. Consult page 56 for ordering.
