Demon Carburetor - The Demon Within

This Line Of Fuel Meters Helps Brings Out The Beast In Performance

If you're going to upgrade your carburetor, you should seriously consider upgrading what feeds it as well. This is the BG 220HR fuel pump and bypass regulator that's designed to flow 220 gph continuous on the street. It would also make a great street/strip fuel supply and we know of at least one 10-second car running this as its sole pump.

Carburetor modifiers like Barry Grant used to get lots of money for installing modified boosters in carbs. Now the tuner can swap boosters in minutes on all RS Demon carbs. Annular, dogleg, and straight boosters are all available. The annular discharge booster shown here pulls a strong signal and can make great power when combined with the black or silver venturi sleeves. It's too big to use with any of the smaller sleeves.
