Review HOLLEY Cfm Alcohol Carbs fits 850

The Holley FRQ-8 850 CFM Alcohol Carburetor is a high-performance fuel delivery system specifically designed for racing applications that utilize methanol or ethanol fuel. This carburetor is part of Holley's series of high-flow, fuel-injector-compatible carburetors, making it an excellent choice for racers looking to maintain the benefits of fuel injection while retaining the traditional look and feel of a carburetor.

The FRQ-8 features an 850 CFM (cubic feet per minute) primary venturi, which provides ample fuel delivery for high-horsepower applications. The carburetor also includes a 650 CFM secondary venturi, which ensures smooth and consistent fuel delivery during wide-open-throttle acceleration. The venturi sizes are adjustable via removable spacers, allowing fine-tuning of the fuel mixture for optimal engine performance.

One of the standout features of the FRQ-8 is its ability to accommodate fuel injection-style components, such as electric choke, electric fuel pump, and electronic ignition. The carburetor comes with a Holley SysteMax fuel pressure regulator, which is designed to maintain a consistent fuel pressure of up to 15 psi. The regulator can be easily adjusted using the external pressure adjustment knob.

Another notable feature is the FRQ-8's self-adjusting fuel level sensor. This sensor monitors the fuel level in the float bowls and automatically adjusts the float height for optimal fuel delivery, eliminating the need for manual adjustments. Additionally, the carburetor includes a built-in fuel pressure relief valve, which prevents fuel pressure spikes and helps maintain consistent performance under various conditions.

The FRQ-8 is constructed from high-quality materials, including a billet aluminum base and brass bodies. The carburetor is also equipped with heavy-duty, chrome-moly steel float bowls, which provide excellent durability and resistance to corrosion. The carburetor comes with a set of Holley's famous "H-Port" intake manifolds, which offer excellent intake flow and power gains.

In summary, the Holley FRQ-8 850 CFM Alcohol Carburetor is a high-performance, fuel-injector-compatible carburetor designed for racing applications that utilize methanol or ethanol fuel. Its large primary and secondary venturis ensure ample fuel delivery for high-horsepower applications, while its ability to accommodate fuel injection-style components makes it an excellent choice for racers looking for the best of both worlds. With its self-adjusting fuel level sensor, built-in fuel pressure relief valve, and high-quality construction, the FRQ-8 is a reliable and powerful fuel delivery system that is sure to meet the demands of even the most demanding racing applications.
