WEBER MANIFOLD for PERIPHERAL PORT 13B 48 or 51IDA RB PERIPHERAL PORT HOUSING
Weber Manifold for Peripheral Port 13B 48 or 51IDA
This manifold is designed to fit the Racing Beat Periperal Port 13B Rotor Housings.
Works with IDA carbs from 48mm to 52mm bore.
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 Modifications
Each carburetor is based on a standard Weber 48mm IDA and then extensively modified in-house by Racing Beat during the conversion process. Using tuning techniques discovered during Racing Beat’s early racing days, these same techniques and modifications are utilized in the methodical transformation of the carburetor as it enlarged to become the Racing Beat 51 IDA.At the start of each carburetor transformation each unit is completely disassembled and inspected. The carburetor bore is machined to the larger 51mm diameter, fitted with precision-made aluminum venturis, emulsion tubes, main and air jets, needle-and-valve, hand-crafted dual throttle plates and shaft, and enlarged diameter air horns with retaining ring.
As delivered, the Racing Beat Weber 51mm IDA carburetor is tuned specifically for a 13B Peripheral Port engine. The Racing Beat Weber 51 IDA carburetor is also suitable for use on a number of rotary engine applications, including a 13B bridge or J-bridge ported engine, or the 12A peripheral ported engine. If the 51 IDA carb is intended for use on these engines; we offer the appropriate Weber components to properly re-tune the carb for these applications. Follow this link for a listing of tuning recommendations for various rotary engine applications. (PDF)
Air Filtration
When considering air filtration for the Weber carburetor you have several options. Open air horns are not recommended due to possibility of engine damage if any debris are ingested by the carburetor. A simple, effective and attractive option are to install a pair of mess air screens. These offer reasonable protection from larger objects, but lack the serious filtration properties of an air filter. The K&N Air Filter Kit is an excellent and easy-to-install option, but the height of the air horns must be trimmed due to clearance concerns within the filter housing. For a dedicated racing application we suggest the fabrication of an enclosed cold-air box. We supply a simple drawing with the instructions highlighting our suggestion for a design, your final design will vary with your application.Performance Comparisons
The selection of an appropriate intake system requires that many factors be taken into consideration. Various intake systems yield different performance characteristics based upon specific engine, exhaust and driveline selections. Due to the complexities associated with these configurations, it is difficult to determine exact power gains for specific applications. Use this intake reference guide (PDF) for performance comparisons between the Weber and Holley Intake systems that we offer.Browse our Weber Carbs, Manifolds and Parts section

AIR FILTER FOAM, 79-85 CARBURETED
Foam Air Filter for Carbs 79-85
The Racing Beat-designed Foam Air Filter Element for all 1971-85 Rotaries (except 1984-85 GSL-SE) consists of a polyurethane foam over a metal screen form that interchanges exactly with the stock element. The foam element can be re-used by periodically cleaning in solvent and re-oiling. While the element offers no significant increase in air flow when compared to a clean, stock paper element, as the paper element collects dirt its air flow capacity decreases dramatically while the foam element is nearly unaffected.
