  • Main Body, Oversize Dominator

    OVERSIZE DOMINATOR® Main Bodies

         When boring the throttle bores in Dominator® carburetors one problem that is encountered is the transfer slot. As the diameter of the throttle bore increases, the width of the transfer slot increases as well. This results in a very rich idle and poor part throttle operation. Also, as the throttle plate gets larger, its position in the bore changes vertically requiring the transfer slots position to change accordingly. In the past, most carburetor tuners and builders have simply tried to calibrate around this situation.

         BLP has designed a special idle transfer slot circuit that goes into the main body at the same angle as the throttle plates. This insures the transfer slot location to be the same, regardless of the throttle bore size. The transfer slot plug extends into the throttle bore so that when the throttle bore is machined, the transfer slot is machined with the bore. The transfer circuit is independent from all the other circuits and any casting porosity in the main body has no effect on the circuit.

         First the bodies are machined for removable BLP transfer slots and then installed at the correct relation to the throttle shaft bore. The air entry radius is profiled, the venturi machined and then the throttle bore is machined. This machining operation is performed on a CNC Lathe using one continuous tool path. We can machine any venturi and throttle bore size you desire, however, on the 1050 HP and 1150 HP the maximum throttle bore size is 2.100. The maximum throttle bore size on the 1250 HP is 2.200. Due to the fact that we are machining a casting, some porosity may occur.
