Bendix Stromberg Carburetor Identification Scheme

Bendix Stromberg used a unique identification scheme where a series of letters and numbers were assembled to identify and describe how a carburetor was constructed. The first two letters described the carburetor design, followed by a number that identified the size, and numbers and letters to identify specific design details and modifications.

The first (two) letter(s) comprise a Basic Design Code that places the Bendix Stromberg carburetor in a design category, where:

  • “A” – Pressure Injection Carburetors
  • “E” – Pressure Injection Carburetors
  • “NA” – Float-Type Carburetors
  • “P” – Pressure Injection Carburetors
  • “Q” – Pressure Injection Carburetors
  • “R” – Fuel Injection Systems
  • “S” – Speed Density Metering Systems

Example: NA-R9G
Prefix- “NA” – for float-type carburetors followed by a “-“(dash)

The next letter indicates type, where:

  • “S” – Single venturi updraft designed for two, three and four cylinder engines in the 25~95 hp class. NOT fitted with economizer, acceleration pump or mixture controls.
  • “R” – Single venturi updraft, designed for engines of all types in the 50-400 hp class. All are similar in design and incorporate needle valve type mixture control, accelerator pump and economizer. Some bodies are interchangeable in this series and deferent design economizers are used.
  • “D” – Double updraft venturi, with the float chamber to the rear, was considered obsolete c.1930
  • “U” – Double updraft venturi, with the float chamber between barrels. See specific models for details.
  • “Y” – Double vertical venturi (updraft), with two float chambers fore/aft of barrels. See specific models for details.
  • “L” – Inverted, down draft venturi.
  • “T” – Triple venturi, double float chamber fore/aft of barrels. The NA-T4 series is the only known model. Designed for use on Wright J-5 and other 9-cylinder radials, where each venturi feeds three cylinders. It has float similar to Y series, but with back suction mixture control. No economizer or accelerator pump.
  • “F” – Four-venturi with two separate float chambers. The last letter and numbers indicate a specific model

Holley Carburetor

Earl Holley’s fascination with airplanes catalyzed the establishment of an aviation division within Holley in 1927. Initially, Holley carburetors found application exclusively in Curtiss-Wright sport planes. However, their usage expanded rapidly to include American Airlines, Pan-American Airlines, the U.S. Coast Guard, as well as various armed forces in Argentina, China, the Dutch East Indies, Thailand, Great Britain, and the United States, all adopting Holley carburetors.

Holley Performance Parts traces its roots back to 1896 when it initially focused on manufacturing motorcycles and various automotive devices. However, it wasn’t until the period between 1926 and 1945 that Holley made significant strides in the aviation industry by producing aircraft carburetors for both military and commercial purposes. Notable clients during this time included Pan American, American Airlines, and Curtiss-Wright.

In 1935, Holley achieved a breakthrough in carburetor technology with the development of the variable venturi carburetor. This innovative design was instrumental in addressing carburetor icing issues that plagued aircraft performance. It made its debut on prominent aircraft such as the C-47/DC-3 and played a crucial role in the success of missions like the historic Doolittle Raid, where B-25 bombers equipped with Holley carburetors showcased their reliability and performance under challenging conditions.

Holley’s contributions to aviation during this era underscored its commitment to innovation and engineering excellence, solidifying its reputation as a trusted provider of high-quality components for the aerospace industry.
