What You'll Learn
358 Modifieds burn gasoline
358 Modifieds are a type of car used in dirt oval racing, a motorsport with a passionate fan base, particularly in the northeastern United States, Canada, and as far south as Florida. These cars are powered by gasoline engines, burning gasoline as they race around the track.
The 358 Modified is a relatively new addition to the dirt oval racing scene, offering an exciting driving and viewing experience. With over 500 horsepower, these cars have impressive acceleration and top speeds, making them a force to be reckoned with on the racetrack. They are slightly less powerful than the premier Big Block Modifieds, but still pack a punch and provide an exhilarating ride.
The 358 Modifieds typically have a midweight of around 2500 pounds and are equipped with a 24-gallon fuel tank. This gives them the necessary range to endure the demands of dirt oval racing. The engine size and fuel capacity contribute to their impressive performance and make them a popular choice for both beginners and experienced drivers looking to hone their skills.
As with any racing car, the fuel system and engine configuration of the 358 Modifieds are carefully designed and optimized for performance. The rules and regulations governing the 358 Modifieds, as outlined by DIRTcar, include specific guidelines for the engine compartment, materials used, ground clearance, and seat location, ensuring both safety and fairness in competition.
While the 358 Modifieds burn gasoline to fuel their races, it's important to note that the world of motorsport is constantly evolving, and alternative fuel sources are being explored and adopted in various racing series. Gasoline, however, remains the staple fuel for 358 Modifieds and many other racing categories, with its high energy density providing the power and speed demanded by these thrilling vehicles.

They have a fuel capacity of 24 gallons
Modified 358 cars are incredibly popular throughout the northeastern United States and are used for dirt oval racing. These cars have a fuel capacity of 24 gallons.
The 358 Modified is the less powerful cousin of the premier Big Block Modified, with a smaller engine and slightly lower weight. Nonetheless, with 510 horsepower, it is still not for the faint of heart. The 358 Modified is a good learner car for those interested in dirt oval racing.
The engine of the 358 Modified is a staple of local dirt modified racing. The base package averages 608 horsepower and 511TQ on gas, with even bigger numbers possible with upgrades. The engine is built with top-quality components to assure power and reliability.
The fuel capacity of 24 gallons gives the 358 Modified a good range and allows drivers to focus on their skills without having to worry about frequent refuelling. The car has a top speed and acceleration time that are impressive for a dirt oval racecar.
In terms of fuel type, some sources indicate that the 358 Modified can run on race gas, with a maximum compression ratio of 14:1. However, other sources mention the use of methanol (carb only) and alcohol engines, with a maximum compression ratio of 11.5:1.

358 Modifieds can also run on methanol
Methanol has several advantages as a fuel for 358 Modifieds. First, it has a high energy density, which means that it can provide a significant amount of power for the engine. Second, it has a high flame speed, which can improve the engine's performance and responsiveness. Third, methanol is a relatively clean-burning fuel, producing less harmful emissions than other types of fuel, such as gasoline.
One of the main challenges of using methanol as a fuel for 358 Modifieds is that it requires a different engine configuration than gasoline or diesel. Methanol is typically injected into the engine using a fuel injector, rather than a carburetor, and the engine may also require modifications to the fuel lines, pumps, and injectors. Additionally, methanol has a lower boiling point than other fuels, so the engine must be designed to prevent vapor lock, which can occur when the fuel vaporizes before it reaches the engine.
Despite these challenges, methanol can be a cost-effective and environmentally friendly alternative to traditional fuels for 358 Modifieds. It is often made from renewable sources, such as biomass or recycled carbon dioxide, and it produces less harmful emissions, making it a more sustainable option for racing enthusiasts.

The engine has a horsepower of 500-600
The DIRTcar 358 Modified is a popular car in the northeastern United States and Canada. With 510 horsepower, it is an incredibly powerful machine that can reach high speeds and accelerate quickly.
A 500-horsepower engine is a significant milestone for any car, and the 358 Modified achieves this through a variety of means. One way to increase horsepower is by increasing the flow of air and fuel into the engine, which can be done by increasing static compression, cylinder pressure, and the flow of the heads and cam. This can also be achieved through the use of a supercharger or nitrous, which can increase horsepower but may not be durable if the engine and its parts are not strong enough to handle the additional heat and stress.
Another factor to consider is the role of torque in the performance of the engine. While horsepower contributes to the speed of the vehicle, torque is what provides the force to move the car, especially at lower RPMs. Therefore, a high-horsepower engine with low torque may not perform as well as expected unless it also has the necessary gearing and stall converter to utilize that horsepower effectively.
The 358 Modified's engine has been modified to achieve its impressive horsepower, including alterations to the upper frame rails for engine clearance and specific requirements for the kick-ups, seat location, and steering wheel mounting. These modifications allow the engine to produce its high horsepower while also adhering to the rules and specifications set for the DIRTcar 358 Modified class.
Overall, the 500-600 horsepower range is impressive and can result in extremely powerful vehicles, as demonstrated by the DIRTcar 358 Modified.
