  HOLLEY CARBURETOR ONLY, 13B BRIDGE PORT 650 RACING BEAT-MODIFIED

  Racing Beat Modified Holley Carburetor Only Bridgeport 13B (uses 650 cfm carb.)

  We offer the extremely popular Racing Beat-modified High Performance Holley carburetor for the 1974-85 13B 4-Port Bridge-Ported engine application. This 650 cfm – Double Pumper with mechanical secondaries – carburetor is the same modified component that is included in our complete 1974-85 13B 4-Port Bridge-Port Kit. The optional air cleaner assembly, fuel line, and manifold shown are not included, but are available with the complete kit, or as separate items.

  Each carburetor is modified by Racing Beat to maximize the performance of a specific engine application. Every carburetor is disassembled, modified and reworked by a Racing Beat carburetor technician. These modifications are the results of countless hours of engine dyno testing and real-world testing. These extensive modifications are undertaken to increase the airflow to meet the demands of the rotary engine. 

  This carburetor requires the use of a high performance fuel pump delivering 6 psi @ 20 gph, we suggest the use of the Mallory 4070M unit.

  For optimum performance, combine this Holley carburetor with a matched Racing Beat intake manifold and the Holley Float Bowl Fuel Line.

  AIR FILTER HOUSING, RACING BEAT HOLLEY WITHOUT FILTER

  Racing Beat Air Filter Housing Without Filter for Racing Beat Holley Carburetor

  Racing Beat’s dyno-proven Power Pulse Air Filter Assembly, for the Holley Carburetor, is designed specifically for performance. While the assembly uses the same Racing Beat foam air filter element that fits the stock canister, the design of the Power Pulse canister both improves air flow into the carburetor and limits the introduction of dirt particles into the filter element. The spun aluminum canister pieces are powder-coated white for added durability.

  The Power Pulse Air Filter Assembly fits most Holley 465, 550, 600, and 650 CFM carburetors (specifically, all Racing Beat Holley Intake System Kits). There is no provision for emission control valve hose/air pump hose connections on this assembly; however, there is a position available to connect a crankcase breather tube if needed.

  HOLLEY CARBURETOR ONLY, 13B 4 PORT STREET PORT 600 CFM RACING BEAT MODIFIED

  Racing Beat Modified Holley Carburetor Only, Street port 13B 4-Port (uses 600 cfm carb.) 

  Racing Beat’s Holley Intake Kit for the 1974-85* 13B 4-Port Street Port engine has proven over the years to be an extremely reliable carburetor upgrade, with very “streetable” engine smoothness and drivability characteristics. We offer the carburetor included with this kit seperately for those looking for a replacment for the orignal Racing Beat-modified unit. The carburetor we supply for the 13B 4-Port Street Port applications features a 600 CFM model utilizing a mechanical choke and mechanical secondaries. As supplied, this carburetor does not include the mounting and attachment hardware that was originally supplied with the complete kit.

  The heart of each intake system is a performance-proven Holley carburetor. Depending on the requirements of each specific application, the carburetor is disassembled by Racing Beat’s carburetor technicians then reworked, retuned, and reconfigured specifically for use with a designated rotary engine application. This process is not a simple “re-jetting” project, but a complex series of steps requiring machining, drilling and reconfiguring of the main and metering bodies, adjustment of the float bowls, and complete replacement of all jets.

  MANIFOLD HOLLEY, 84-92 6-PORT ALL

  Holley Manifold, 84-92 13B 6-Port All

  The Racing Beat-designed intake manifold for the 1984-92 13B 6-Port rotary 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 RX-7 street or custom race applications.

  Please note:  it is highly recommended that the intermediate housing be port-matched to the manifold when using this manifold with the 1984-5 13B 6-Port engine configuration.

  All of Racing Beat’s 13B intake manifolds for Holley carburetor applications are sand-cast by a local foundries and delivered to our in-house production shop for all machining and surface finishing processes. Select manifolds are then hand-ported to match a specific intake port configuration for an 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!

  If needed, an engine-to-manifold gasket (1984-85), (1986-88), or (1989-92), and/or Holley base gasket are available separately.
