Oval Track (OT) carburetors are designed for effortless drivability on dirt or asphalt. Carbs have customized metering circuits developed for rapid throttle response and excellent mid-range and top end power.
 The Race Demon Traction Master is an innovation that provides alternate timing of the opening of the secondary throttle plates to adjust for changing track conditions. Four timing cams are included. Traction Master (TM) carburetors have all the features of the OT version but are fitted with the Traction Master baseplate assembly. The Traction Master provides greater throttle control and its benefits to the oval track racer, both dirt and asphalt, are considerable.
 The Race Demon 2-barrel carburetor is designed for oval track applications that require 500 CFM but do not specify Holley 4412 carburetors. This is the ultimate Holley 4412 replacement.
Holley 500CFM Remanufactured Circle
Track Carburetor Remanufactured Holley 12 carb is set up for circle track racing. The choke has been removed; circle track float & metering block are installed.
These carburetors are engineered and built by a major engine builder for the discriminating racer looking for the maximum competitive edge when carburetor rules restrict or prohibit modifications. For all types of racing, these carburetors are carefully blueprinted yet retain the tolerances of a stock 4412 Holley which will past most tech inspections. Horsepower gains that can be seen on the dyno and felt at the race track are achieved through superior air flow characteristics and balanced fuel metering produced by careful preparation of the carburetors.
