CreditParts modification technology for the mass market – Modification Parts Introduction Guide
For racing novices, improving the power of a car is a complex project, involving the optimization and transformation of the engine, intake and exhaust system, fuel system, etc. The following are some common methods:
Engine Parts
Piston and piston ring
Replace the piston and piston ring with lightweight and high-strength ones to reduce the weight of the piston assembly, reduce the inertia of movement, make the engine more responsive, and improve the sealing of the piston ring, reduce the leakage loss, and increase the power output of the engine.
Crankshaft and connecting rod
Forged crankshaft and connecting rod are used, which have higher strength and fatigue resistance and can withstand greater torque and power output. At the same time, the lightweight design also helps to reduce the rotating mass of the engine and increase the speed of speed increase.
Camshaft
Replace the high-performance camshaft, by changing the profile and lift of the cam, adjusting the opening and closing time and lift size of the valve, so that the engine can more effectively intake and exhaust at different speeds, improve the charging efficiency, and thus increase the power.
Engine management system
Upgrade the program of the engine control unit (ECU) or replace the high-performance ECU, optimize the engine’s ignition timing, fuel injection amount, valve timing and other parameters, so that the engine can be in the best working state under various working conditions and give full play to its power potential.
Intake and exhaust system
Intake system
Air filter: Replacing a high-flow air filter can allow more air to enter the engine smoothly, increase the intake volume, and thus improve combustion efficiency and power output.
Intake pipe: Use a large-diameter, smooth-walled intake pipe to reduce the resistance of airflow, allowing air to enter the engine more quickly and increase intake efficiency.
Exhaust system
Exhaust manifold: Modify the exhaust manifold to an equal-length exhaust manifold so that the exhaust gas discharged from each cylinder can be discharged more evenly and smoothly, reduce exhaust interference, improve exhaust efficiency, and thus increase the power of the engine.
Three-way catalytic converter
Replace the high-performance, low-resistance three-way catalytic converter to reduce exhaust back pressure while ensuring that exhaust emissions meet standards, so that exhaust gas can be discharged from the engine more quickly and the engine can breathe more smoothly.
Exhaust pipe
Use a large-diameter, smooth-walled exhaust pipe to reduce exhaust resistance, so that exhaust gas can be quickly discharged from the vehicle, improve the exhaust efficiency of the engine, and provide better conditions for intake, thereby increasing power.
Fuel System
Fuel pump:
Upgraded to a high-pressure, high-flow fuel pump, which can provide sufficient fuel pressure and flow when the engine is running at high load, ensuring that the engine can obtain sufficient fuel to support higher power output.
Injector:
Replace with a high-flow injector, when the engine needs more fuel, it can accurately spray enough fuel to match the increased intake volume, achieve more complete combustion, and increase power.
Other aspects
Reduce the weight of the car body
By using lightweight materials such as carbon fiber and aluminum alloy, replacing body panels and chassis components, etc., the overall weight of the car can be reduced. According to the principles of physics, when the power remains unchanged, the weight of the vehicle is reduced and the acceleration increases, thereby improving the power performance and handling performance of the car.
Optimize tires and rims
Choose high-performance tires with stronger grip, which can provide better adhesion during acceleration, braking and cornering, so that the power of the engine can be more effectively transmitted to the ground and reduce power loss. At the same time, replacing lightweight rims and reducing the rotational inertia of the wheels can also help improve the acceleration performance of the car.
