  MANIFOLD HOLLEY, 74-78 12A

  Holley Manifold, 74-78 12A Stock port

  The Racing Beat-designed intake manifold for the 1974-78 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.

  All of Racing Beat’s 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!

  HOLLEY CARBURETOR ONLY, 12A 465 CFM RACING BEAT MODIFIED

  Racing Beat Holley Carburetor Only Stock port 12A 76-85 (465cfm carb) Discontinued
  

  Sorry, this item has been discontinued by the Manufacturer

  We offer the extremely popular Racing Beat-modified High Performance Holley carburetor – 465cfm body – for the 1976-85 12A Non-Ported engine application. This carburetor body is the same modified component that is included in our complete 1976-85 12A Non-Ported engine kit. The optional air cleaner assembly 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.

  Complete Ready-to-Install Kit
  One of most significant benefits of this complete ready-to-go kit is that is takes all the guesswork, trial-and-error, and frustration out of attempting to assembly your own intake kit! We’ve taken over 40 years of our rotary engine experience and know-how and combined it for you in this complete, ready-to-install kit. Our intake kits has been thoroughly developed and tested using our in-house engine dyno to ensure maximum performance for each specific engine application.

  Rotary-tuned By Racing Beat
  The heart of each intake system is a performance-proven 4-barrel 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. Each application has been fully developed and tested on our in-house dyno facility to ensure maximum performance.

  Each comprehensive package includes a Racing Beat cast-aluminum high-rise intake manifold with a vacuum source for power brakes, a Racing Beat-modified Holley carburetor (465 CFM), foam air cleaner and canister assembly, throttle and metering oil pump linkages, and appropriate gaskets. All emissions control fittings are eliminated. This carburetor includes a vacuum-operated choke.

  Performance
  When installed on a 1976-78 RX-3 or a 1979-85 RX-7 12A engine, this kit increases engine output by approximately 20 HP with the stock exhaust system. However, for increased performance gains we strongly recommend the installation of an exhaust header/presilencer/Power Pulse Muffler combo (10+ HP) or an open exhaust (15+ HP) – resulting in total performance gains of between 30-35 HP depending on your specific intake/exhaust configuration..
