Intake System

The Racing Beat-designed and manufactured Peripheral Port Intake Manifold mates a Weber 48 IDA or 51 IDA downdraft carburetor, or equivalent throttle body, to the Racing Beat-manufactured 13B peripheral port housings. (This manifold cannot be used on the Mazda Factory Race MFR housings.)

The steel tubing manifold is attached to the rotor housings with hoses that are included. A simple support bracket fabricated for your particular application, typically attached from the carburetor-manifold junction to the threaded bosses on top of the rotor housings, will complete the task.

Racing Beat 51mm IDA Weber

Both the elegant design and the simplicity in the maintenance of the WEBER Carburetors have proven to be compelling reasons as to why the Weber name has remained so popular over the years.

These are made to order, don't expect it in a hurry.

The Racing Beat-designed intake manifold for the 1971-73 12A Stock and Street-ported engine is ideally suited to meet the performance requirements of the Holley carburetor. Designed by Chief Engineer/Engine Builder Jim Mederer, these cast aluminum intake manifolds have proven themselves in a variety of street and race applications.

Racing Beat manifolds for Holley applications are cast by a local foundry then delivered to our in-house production shop for final machining and surface finishing. Each manifold is hand-machined to match the specific intake port configuration of the intended engine application. Further machining is then undertaken to match the base-plate surface to the Holley carburetor base. These critical machining steps ensure a positive fitment between both the engine surface and the carburetor base. Every manifold is then surface finished using a ball-burnishing process that enhances the final appearance of the aluminum material. Once these labor intensive processes have been completed these manifolds look as good as they perform!

This manifold includes a vacuum source for power brakes.
