Drag Racing

Drag racing is a high-speed motorsport that involves two vehicles competing side-by-side on a straight-line track. The objective is to accelerate from a standing start and cover a specific distance, typically a quarter-mile, in the shortest possible time.

Drag racing showcases raw power, acceleration, and driving skills. The sport caters to various classes of vehicles, including cars, motorcycles, and even specialised dragsters built for sheer speed.

With intense bursts of acceleration, roaring engines, and thrilling head-to-head competition, drag racing provides an adrenaline rush for both participants and spectators.


Drag racing originated in the United States in the early 20th century, emerging from the illegal street racing scene. It gained popularity after World War II, as servicemen returning home sought an outlet for their need for speed.

Organised drag racing events started to take place in the 1950s, and the National Hot Rod Association (NHRA) was formed in 1951 to regulate and govern the sport. Over the years, drag racing evolved with advancements in technology, resulting in faster, more powerful vehicles and the development of dedicated drag strips. Today, drag racing is a recognized motorsport, attracting enthusiasts worldwide.


In the fast-paced world of drag racing, every millisecond and horsepower counts. That’s where electronic fuel injection (EFI) systems come into play, revolutionising the way fuel is delivered to the engine and enhancing the performance of drag racing vehicles.

Electronic fuel injection replaces traditional carburetors with a more precise and efficient fuel delivery system. It uses electronic sensors and actuators to precisely control the fuel and air mixture going into the engine, based on various factors such as engine speed, throttle position, and intake air temperature. This precise control allows for optimal combustion, resulting in improved throttle response and increased power output.

One of the significant advantages of electronic fuel injection in drag racing is the ability to tune and adjust fuel delivery parameters with precision. Racers can make fine adjustments to the air-fuel ratio, fuel flow rates, and ignition timing to achieve optimal performance for their specific engine setup. This level of control allows drag racers to fine-tune their engines to extract maximum power and acceleration, gaining a competitive edge on the race track.

EFI systems also offer the advantage of improved fuel efficiency. By delivering the precise amount of fuel needed for combustion, electronic fuel injection eliminates the fuel waste associated with traditional carburetors. This efficiency translates to more power being generated from each drop of fuel, allowing racers to achieve better performance while optimising fuel consumption.

Furthermore, electronic fuel injection systems can incorporate advanced features such as data logging and engine management capabilities. This enables racers to monitor and analyse engine performance data, make on-the-fly adjustments, and diagnose potential issues. The ability to gather real-time data and fine-tune engine parameters can greatly enhance the overall performance and reliability of drag racing vehicles.

With electronic fuel injection, drag racers benefit from improved throttle response, increased power output, fuel efficiency gains, and advanced engine management capabilities. It has become an integral part of the sport, allowing racers to push the limits of performance and achieve faster and more consistent runs down the drag strip.
