The Holley 9377 Dominator is a high-performance carburetor that is designed to deliver exceptional fuel flow and air/fuel mixture for maximum horsepower and engine performance. This carburetor is part of Holley's Dominator series, which is known for its robust construction, easy tunability, and high-flow capabilities.
The 9377 Dominator features a 750 CFM (cubic feet per minute) primary venturi, which is larger than many other carburetors in its class. This allows for a greater fuel flow, providing the engine with the necessary fuel to produce more power. The secondary venturi is adjustable, allowing for fine-tuning of the fuel/air mixture to optimize performance at different RPM ranges.
The carburetor is equipped with a unique bowl design that helps to reduce fuel spillage and improve atomization. This, in turn, leads to a more complete and efficient combustion, resulting in improved engine performance and fuel efficiency. The bowl is also made of aluminum, which is lighter than traditional materials, reducing the overall weight of the carburetor and improving engine response.
The 9377 Dominator features a vacuum secondaries system, which allows the secondary circuits to open and close based on engine vacuum. This system helps to prevent over-fueling at high RPMs and ensures that the engine receives the correct fuel/air mixture at all times. The carburetor is also equipped with a mechanical fuel pump, which is capable of delivering up to 12 gallons per hour, ensuring that the engine has a constant supply of fuel.
The 9377 Dominator is easy to install and tune, thanks to its removable linkage system and adjustable fuel and air metering components. The carburetor is also compatible with a wide range of fuel systems, including Holley's EFI systems, making it a versatile choice for a variety of performance applications.
In summary, the Holley 9377 Dominator is a high-performance carburetor that delivers exceptional fuel flow and air/fuel mixture for maximum horsepower and engine performance. Its unique bowl design, adjustable secondary venturi, and vacuum secondaries system make it a reliable and efficient choice for performance enthusiasts. Its easy installation and tuning, as well as its versatility in terms of fuel systems, make it a popular choice among car builders and racers.
