Carb Class: Annular Boosters

Carb Class: Annular Boosters

Boosters are one of the most critical areas of a carburetor in terms of performance. Everything done to tune an engine is dependent on the correct booster and how well it is matched to the application. Annular boosters are found on every style of carburetor we make and proper research should be done to determine your specific needs. Annular boosters employ several small holes to discharge the air/fuel mixture into the venture, whereas all other types of boosters (i.e. downleg, straight) use one hole. Think of the difference between boosters the same as you would the difference between a water hose and a shower head. Annular boosters provide better fuel atomization and could increase power and torque depending on your application. The emphasis here is that not all applications will benefit from an annular booster – for more details about our current carburetor configurations or annual boosters, call our technical service phone line at 270-793-0900
