What Is a Blow Through Carburetors

A blow through carb is a type of carburetor used in turbocharged engines that supplies the fuel-air mixture under pressure to the engine. This type of carburetor is designed to withstand the increased pressure generated by a turbocharger, where a standard carburetor would fail.

Blow through carb, as the name suggests, works in a way that is different from the regular carburetors. This type of carburetor is mainly used in turbocharged engines, where the air is compressed before it enters the engine.

The compressed air is then mixed with the fuel and delivered to the engine’s combustion chamber, resulting in increased power output. The blow through carb has a different design compared to regular carburetors, which allows it to handle the increased air pressure generated by the turbocharger.

In this article, we will discuss how the blow through carb works and its advantages and disadvantages over regular carburetors.

What Are Carburetors?

Carburetors are an integral part of automobile engines that mix fuel and air for the combustion process. The carburetor’s main function is to regulate the flow of fuel to the engine through a complex series of valves, chambers, and tubes.

There are several types of carburetors, with each type having unique characteristics and advantages. Blow-through carburetors are one such type that uses a positive displacement blower to deliver fuel and air mixture to the engine. Proper selection of carburetors is crucial to ensure optimal engine performance and efficiency.

The carburetor’s role in fuel and air delivery cannot be ignored, and thus, it is essential to keep your carburetor in good working condition for maximum engine output.

What Is A Blow Through Carburetor?

A blow through carburetor is a type of carburetor commonly used in turbocharged applications. It is designed to handle higher levels of boost pressure than a standard carburetor by dispersing the fuel throughout the airflow. The history of these carburetors dates back to the 1970s when they were first used in drag racing.

Compared to traditional carburetors, blow through carburetors require additional modifications to work properly, including the use of a fuel pump and regulator. Although they can provide improved power and efficiency, blow through carburetors can be challenging to tune and may experience fuel distribution issues.

Proper installation and tuning are critical for optimal performance.

How Does A Blow Through Carburetor Work?

The blow through carburetor is a unique type of carburetor that is designed to work with forced induction systems. The working process involves components such as a compressor, fuel pump, carburetor, and intercooler. Fuel and air play a vital role in the process, as the carburetor must deliver the correct fuel-to-air ratio for optimal performance.

The compressor sends compressed air into the carburetor, and the fuel pump delivers fuel to mix with the compressed air. This mixture is then transferred to the engine for combustion. The blow through carburetor can handle high boost pressures and provides consistent performance under harsh conditions.

With an understanding of the components and process, mechanics can tune the blow through carburetor to unleash the full potential of the engine and forced induction system.

Installing And Tuning A Blow Through Carburetor

Blow through carburetors are a popular choice among car enthusiasts who want to achieve maximum horsepower. Installation and tuning are crucial to obtaining optimal performance. Preparation involves gathering the right tools and thoroughly cleaning the carburetor. The next step is to carefully follow a step-by-step guide to installing the carburetor.

Tuning tips include adjusting the air/fuel ratio, selecting the right jets, and making sure the carburetor is properly sealed. With proper installation and tuning, a blow through carburetor can significantly increase horsepower and performance. By following these steps, you’ll be on your way to enjoying a powerful and efficient ride.

Frequently Asked Questions On What Is A Blow Through Carb
