Outlaw sprint cars are tube-frame open-wheel racers designed to be lightweight and aerodynamic. They are typically powered by a high-torque internal combustion engine, usually a small block V8 or 305 cubic-inch V8 engine. The most common engine size for sprint cars in the United States is 410 cubic inches, and they can reach speeds of over 140 mph. Outlaw sprint cars can also feature other engine options, such as a 360 cubic inch engine or turbocharged engines, which can exceed 1000 horsepower. The type of engine used depends on the track, with 410 cubic inch engines preferred for short and dirt tracks, and 360 cubic inch engines optimal for longer ovals. Sprint cars running methanol may produce more power due to the higher octane rating of the fuel.

What You'll Learn
Outlaw sprint cars can use methanol fuel
Outlaw sprint car racing is a thrilling sport that pushes the limits of speed and power. At the heart of these racing machines is their fuel system, and one of the critical choices in this domain is the fuel type. Outlaw sprint cars can use methanol fuel, and this choice of fuel has been a topic of debate among racers and enthusiasts. Methanol has been a traditional racing fuel in the US since 1927 due to its high octane rating, which was significantly higher than that of gasoline at the time.
Methanol offers several advantages for sprint car racing. Firstly, it has a higher octane rating than gasoline, providing increased power and performance. Secondly, methanol is easier to tune, allowing for more forgiveness in the fuel mixture, whether it is too lean or too rich. This flexibility can be advantageous for optimizing engine performance. Additionally, methanol burns without exploding, enhancing safety, especially in the event of a crash.
However, there are also considerations and challenges associated with using methanol fuel in outlaw sprint cars. One significant drawback is methanol's lower energy density compared to gasoline. Methanol requires almost twice the volume of gasoline to feed the same-size engine, leading to larger fuel tanks and more frequent fuel stops during races. This higher fuel consumption also contributes to increased costs, as teams need to budget for a larger quantity of fuel.
Another factor to consider is the impact of fuel burn on car handling. As methanol burns, it can significantly change how the car handles, requiring teams to constantly predict and adjust for the car's behaviour at different fuel levels. This adds a layer of complexity to the race strategy and car setup. Furthermore, methanol's combustion characteristics can make it challenging to detect during the daytime, as it burns clear or with a pale blue colour at night.
While some racers prefer methanol for its traditional appeal and tuning flexibility, others opt for gasoline due to cost considerations and handling consistency. Ultimately, the choice between methanol and gasoline in outlaw sprint car racing depends on various factors, including performance, safety, cost, and each team's unique strategy.

Outlaw sprint cars can use racing fuel
Outlaw sprint cars are an exciting, high-speed spectacle, with powerful engines and lightweight, aerodynamic designs. These cars can reach speeds of over 140 mph, with some modern sprint cars reaching almost 150 mph. The power of these cars is impressive, with 900 horsepower in a car weighing just 1400 pounds, including the driver.
The engines used in outlaw sprint cars are typically small block V8 or 305 cubic-inch V8 engines, with the most common type being the 410. The 410 engine is a medium-size V8 engine produced by the Ford Motor Company, with a capacity of 6.7 liters. Outlaw sprint cars can also use other engine options, such as a 360 cubic inch engine, or even turbocharged engines, which can produce over 1000 horsepower.
The type of fuel used in these cars is an important consideration. Outlaw sprint cars can use racing fuel, with some running on methanol, which can increase power output due to its higher octane rating. The exact amount of fuel a sprint car holds will vary depending on the model and engine type. Typically, fuel tanks in these cars range from 15 to 35 gallons, with larger cars tending to have bigger tanks. For races without pit stops, larger fuel tanks are essential to finish the race without refueling.
The cost of constructing and maintaining an outlaw sprint car can be significant. The base cost of materials can range from $5,000 to $15,000, with high-end parts adding to the expense. Racing fuel, brake pads, and other supplies can cost around $500 for a season, and labor costs can add a further $2,000 to $7,000. Outlaw sprint cars are purpose-built for speed, with every design decision made to maximize performance, resulting in an exhilarating racing experience.

Outlaw sprint cars can use turbocharged engines
The World of Outlaws is a promotional body for winged sprint cars, featuring premier dirt sprint car racing series across the United States. Outlaw sprint cars can use turbocharged engines, with some series allowing for unlimited displacement engines.
Sprint cars are open-wheel race cars, typically weighing around 1,400 pounds (including the driver) and producing over 900 horsepower. They are designed for short oval, circular dirt, or paved tracks. Sprint car racing is particularly popular in the United States, Canada, Australia, New Zealand, and South Africa.
The World of Outlaws consists of two series, with two distinct car classes: Sprint Cars and Late Models. The Sprint Car division includes the NOS Energy Drink World of Outlaws, a series of 6.7L winged sprint cars that compete across the United States and Canada.
Engine specifications for sprint cars can vary depending on the series and location. For example, the International Motor Contest Association (IMCA) sanctions traditional 305 non-winged and winged sprint cars with varying engine configurations. Similarly, the Sprintcar Control Council of Australia (SCCA) oversees sprint car racing in Australia, including the World Series Sprintcars, which also features winged sprint cars.
While specific engine rules may differ, outlaw sprint cars have the capability to utilize turbocharged engines, contributing to their impressive power-to-weight ratios and performance on the track.

Outlaw sprint cars can use 410 cubic inch engines
Methanol is used as fuel in these sprint car engines, requiring almost double the amount of fuel that would be used with gasoline. The engines also feature a fuel injection system, which introduces fuel into the engine's combustion chambers for ignition, and a fuel pump to transfer fuel from the tank to the engine via the fuel line.
The 410 engine specification is so significant that April 10 has been designated "National Sprint Car Day" or "410 Day." This day celebrates the iconic engines of the World of Outlaws NOS Energy Drink Sprint Car Series, which can be watched live at events or on DIRTVision.

Outlaw sprint cars can use 360 cubic inch engines
Sprint car racing is primarily popular in the United States, Canada, Australia, New Zealand, and South Africa. Sprint cars are open-wheel race cars that run on short oval, circular dirt, or paved tracks. They have high power-to-weight ratios, with weights of about 1,400 pounds (including the driver) and power outputs of over 900 horsepower. The standard powerplant of professional sprint car racing today displaces 410 cubic inches, but there are also 360 cubic inch engines used in sprint car racing.
The 360 engines are popular with local racers as they can still provide enough power while being cheaper to build. They have lower power and increased weight compared to the larger engines, but they are still exciting to watch. The 360-powered sprinters can still provide enough power to shower the stands with clay, showing that they don't lack any of the excitement of their more expensive counterparts.
While the standard powerplant of professional sprint car racing is 410 cubic inches, the 360 cubic inch engine is a common alternative, especially for local racers or those looking for a more cost-effective option. The 360 engines are still capable of providing high performance and excitement for both drivers and spectators, making them a popular choice in sprint car racing.
