New 850 CFM Mighty Demon Carburetors with Annular Boosters

Demon-logoANNOUNCING: The 850 CFM Mighty Demon with Annular Boosters! The 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. The 850 Mighty Demon now features larger bore annular boosters which reduce airflow at low RPM for better throttle response. Since they are straight leg boosters, they sit higher in the bore and does not impede mid and upper RPM airflow. Each booster has eight distribution holes for optimum atomization.

The Mighty Demons feature annular boosters, 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” tune up, but can be easily modified using Demon Fuel Systems carburetor service and tuning parts.
