How to Increase HP of Car Engine
Introduction
Horsepower (HP) is a measure of an engine’s power output. It is calculated by multiplying the torque (in pound-feet) by the engine speed (in revolutions per minute) and dividing by 5,252.
There are a number of ways to increase the HP of a car engine. Some of these methods are relatively simple and inexpensive, while others are more complex and expensive.
Simple and Inexpensive Methods
- Install a cold air intake. A cold air intake replaces the stock air intake with a new one that draws in cooler air from outside the engine compartment. This can help to increase engine power by up to 10 HP.
- Upgrade the exhaust system. A new exhaust system can help to reduce backpressure and improve airflow, which can lead to an increase in HP. A cat-back exhaust system is a good option for those who want a moderate increase in power, while a full exhaust system is best for those who want the maximum possible increase in HP.
- Tune the engine. Engine tuning involves adjusting the engine’s air-fuel ratio, timing, and other parameters to optimize performance. This can be done by a professional tuner or by using a do-it-yourself tuning kit.
More Complex and Expensive Methods
- Install a turbocharger or supercharger. A turbocharger or supercharger is a device that forces more air into the engine, which can lead to a significant increase in HP. Turbochargers are more powerful than superchargers, but they are also more expensive and complex to install.
- Increase the engine displacement. Engine displacement is the volume of air that the engine’s cylinders can hold. Increasing the engine displacement can lead to a significant increase in HP, but it is also a very expensive and complex modification.
- Install a performance camshaft. A performance camshaft can help to improve the engine’s breathing and increase valve lift, which can lead to an increase in HP. Performance camshafts are available in a variety of grinds, so it is important to choose one that is appropriate for the specific engine and application.
Conclusion
There are a number of ways to increase the HP of a car engine. The best method for a particular application will depend on the desired increase in power, the budget, and the level of expertise.
