Race Demon

Removable Demon boosters are precision cast from a high-strength zinc alloy. Patent #5807512

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.

The billet baseplates on all Demon carburetors (where featured) are virtually unbreakable, unlike their cast counterparts.

The Race Demon™ is a racers dream. It delivers unmatched features, superior performance and consistency.

The Race Demon™ line is available in a full range of sizes and directly replaces Holley® 4150-style carburetors. Every Race Demon™ has billet-aluminum metering blocks, billet aluminum baseplates, patented removable boosters, large capacity fuel bowls with patented sight glasses and patented, streamlined air entries.

Combined, this cutting edge technology allows Race Demons to produce greater power and achieve higher levels of consistent performance than conventional designs. Race Demon™ carburetors are offered in a variety of factory tune-ups: General Competition (GC), Oval Track (OT), Drag Race (DR), Tunnel Ram (TR) and Road Race (RR). For greater tuning flexibility see the Race Demon RS.

All Race Demons can be serviced and tuned using Demon and BG Fuel Systems carburetor service and tuning parts.


Race Demon float bowls are supplied complete with sight glasses which permit float level adjustments without the risk of fuel spillage. They have a greater capacity than conventional bowls, and some are supplied with a unique anti-aeration dam that settles the fuel and reduces foaming.	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 58 for ordering.
