CARBURETOR HEAT BOX FOR ELLISON TBI

The carburetor heat box and air grid are designed specifically for the Ellison TBI to eliminate carburetor icing problems. There must always be a constant flow of air through a heat muff. The carburetor heat box has an automatic dump of hot air when carb heat is not being used, thereby eliminating the chance of heat muff burnout.

The box has a 2.5” inlet for ram air and a 2” inlet for carb heat. The box is made of 5052 aluminum, stainless steel and 6061-T4 tube. The mounting surfaces, shaft, flapper, arm and rivets are stainless. In addition, the box is strengthened in the mounting hole area to eliminate the possibility of metal fatigue. A 4” inspection/ mounting hole with a cover plate secured by nut plates and screws is locate on the bottom of the box (not visible in the photo.)

The purpose of the air grid is to eliminate air flow turbulence. The 1/2” stainless steel vanes straighten the air before it reaches the throat of the carburetor and achieves better air/fuel distribution. This is a proven performance enhancement technique.
