However, too much boost can also increase the risk of engine damage.Įngine building and tuning are essential components of drag racing that can make all the difference in terms of performance. Adjusting the timing can help optimize performance and reduce the risk of detonation.īoost pressure: In turbocharged or supercharged engines, boost pressure can be adjusted to increase power output. Ignition timing: Ignition timing refers to the timing of the spark plug firing. A lean mixture can cause the engine to run hot and increase the risk of damage, while a rich mixture can reduce power and waste fuel. Some of the key factors that tuners focus on include:Īir/fuel ratio: The air/fuel ratio is the amount of air and fuel that enters the engine. Tuning can involve making adjustments to the fuel injection system, ignition timing, and other key components to achieve the best possible performance. Once the engine is built, tuning is the process of optimizing the engine's performance by adjusting various components and settings. Choosing the right intake manifold can help optimize airflow and improve performance. Intake manifold: The intake manifold is responsible for delivering air and fuel to the engine. High-performance pistons are made from stronger materials and may feature custom shapes or coatings to reduce friction and increase power.
Pistons: Pistons are responsible for converting the energy from the fuel into motion. Choosing the right cylinder heads can make a big difference in terms of airflow and power. Camshafts are available in a wide range of profiles and can be custom-ground to match the specific needs of the engine.Ĭylinder heads: The cylinder heads sit on top of the engine block and contain the valves, valve springs, and other components. Some of the key components that engine builders focus on include:Ĭamshaft: The camshaft controls the opening and closing of the engine's valves, which in turn controls the amount of air and fuel that enters the combustion chamber.
Engine builders must carefully select and match components to create an engine that is powerful, reliable, and efficient. In this blog, we'll explore some of the key aspects of engine building and tuning in drag racing.īuilding a high-performance engine for drag racing requires a deep understanding of engine mechanics and a lot of attention to detail. Engine building and tuning are two key components of drag racing that can make all the difference in terms of performance. In drag racing, a high-performance engine is essential for achieving top speeds and winning races.
