ABSTRACT:
A throttle plate for use with internal combustion engines comprised of a relatively thin piece of material so that installation of the throttle plate between the carburetor or throttle body and intake manifold of a vehicle does not require additional brackets or components to correct throttle cable linkage length or geometry. The throttle plate comprises a plate having apertures to accommodate pre-existing connectors and a perimeter that corresponds to connections between, and the geometry of, the carburetor or throttle body and intake manifold. The plate fits between the carburetor or throttle body and intake manifold and defines at least one airflow hole corresponding to the airflow path in the carburetor or throttle body. If there are multiple airflow paths between the carburetor or throttle body and intake manifold, then there will be multiple airflow holes. One or more vanes integral with the plate extend radially from the perimeter of each airflow hole toward its center. The plurality of vanes can be a variety of shapes, including helical and inclined, and extend into the airflow hole only to the extent they work in proximity of the throttle valve(s) and do not obstruct operation of the throttle valve in the throttle body. As air flows from the throttle valve(s) through the throttle plate and into the intake manifold, the vanes redirect laminar airflow into turbulent airflow.
