Racing Carburetors

By Eric Morris

Tip! (7) Sports Car Racing: Sports car racing takes place in a closed circuit and in this race, purpose-built cars and sports cars production versions compete with each other. This race is particularly for long distances like 1000km and that is why this race involves more than one driver switching between them.

Today, some of the most powerful cars in the world are using carburetors rather than the automatic fuel injection system. This is because to produce torque and horsepower, you require a mixture of air and fuel. A 600-horsepower engine will need about 300 pounds of fuel per hour. The needs of racecars are very different compared to the needs of a typical passenger vehicle. With the large amounts of 'G' forces the cars withstand, you need a fuel delivery system that can compensate for the high pressure they endure.

Another reason why racecars use carburetors rather than electric fuel injection systems is because of their ability to allow the vehicle to accelerate at a very fast rate in the lower gears, allowing it to pick up RPMs very quickly. This rapid acceleration increases the demand for fuel.

What will happen if fuel delivery is weak?

Tip! (4) Touring Car Racing: This type of race involves highly modified production cars and it is comparatively slower than the sports car racing or the single-seater racing. The most popular championship is the World Touring Car Championship.

If your fuel delivery system is weak, your engine will not be as efficient when producing power with regard to the amount of fuel used. When this happens, it may cause your motor to miss or "burn-up" parts. One sure thing that will happen is that you will not receive top performance from your motor. You will not be able to get all of the power you could possibly get. This is why it is important for racecars to have new racing carburetors, camshafts, and flowed heads. Regardless of how advanced the car's carburetor is, if you do not have a fuel delivery system that can handle that much power and maintain correct levels, the carburetor will not be able to disperse the optimum mixture of fuel and air.

What will happen if the fuel system is too large?

There is a misconception that having a fuel delivery system that is too large will hurt performance, which is untrue. It will actually ensure that the type of carburetor you have in your motor will give you an optimum mixture of fuel and air for maximum power.

Tip! Nascar racing, another style of go cart competitions, attracts many people because it closely imitates real Nascar racing by using an oval asphalt track. The Nascar go-cart races are also sprints ranging from 1/10 to � of a mile long.
