When it comes to building a 400 horsepower daily driver, car enthusiasts often find themselves torn between two popular engine platforms: the LS and the Coyote. Both options have their merits, but understanding the differences in components, cost, and performance can help you make an informed decision. In this article, we will compare the budget components of both engines to see how they stack up against each other.
Overview of the LS Engine
The LS engine family, known for its reliability and performance, has become a favorite among car builders. With a wide range of aftermarket support and a robust design, the LS offers a great foundation for building power. Here are some key features:
- Aluminum or iron block options
- Lightweight design
- Strong aftermarket support
- Versatile for various applications
Overview of the Coyote Engine
The Ford Coyote engine, introduced in 2011, has quickly gained a reputation for its power and efficiency. With its DOHC design and modern technology, the Coyote is a formidable contender in the performance world. Here are some highlights:
- Modern DOHC design
- High-revving capabilities
- Good power-to-weight ratio
- Strong performance from the factory
Component Comparison
Engine Block
The engine block is the heart of any build, and both LS and Coyote engines offer solid options. The LS engine can be found in various displacements, with the 5.3L and 6.0L being popular choices for budget builds. The Coyote, on the other hand, comes in a 5.0L configuration.
Heads and Valvetrain
Both engines feature advanced head designs that can support high horsepower. LS heads are known for their excellent airflow capabilities, while Coyote heads utilize a DOHC design that allows for higher RPMs. Choosing the right heads can significantly affect your power output.
Intake and Exhaust
The intake and exhaust systems play a crucial role in performance. LS engines can benefit from a variety of aftermarket intakes and headers, while Coyote engines come with a well-engineered intake manifold and exhaust system that can support substantial power.
Fuel System
A reliable fuel system is essential for any high-performance build. Both LS and Coyote engines can utilize aftermarket fuel injectors and pumps to meet the demands of increased horsepower. However, the Coyote’s direct injection system offers more precise fuel delivery.
Cost Analysis
Budget is a significant factor when building a daily driver. Let’s break down the costs associated with building a 400 HP engine using budget LS and Coyote components.
Budget LS Build Costs
- Engine Block: $1,500
- Heads: $800
- Intake: $300
- Exhaust: $400
- Fuel System: $500
- Total: $3,500
Budget Coyote Build Costs
- Engine Block: $3,000
- Heads: $1,200
- Intake: $400
- Exhaust: $600
- Fuel System: $800
- Total: $7,000
Performance Expectations
When building a daily driver, performance is key. Both LS and Coyote engines can reach the 400 HP mark, but the way they deliver that power can differ significantly.
LS Engine Performance
With the right tuning and components, an LS engine can provide a smooth power band and excellent torque. This can make for a very enjoyable driving experience, especially in a daily driver scenario.
Coyote Engine Performance
The Coyote engine is known for its high-revving nature and impressive top-end power. This can make it feel more aggressive and spirited, particularly when pushed to its limits.
Conclusion
In conclusion, both the LS and Coyote engines have their pros and cons when it comes to building a 400 HP daily driver. The LS offers a more budget-friendly option with ample aftermarket support, while the Coyote provides modern technology and high-rev capabilities. Ultimately, the choice will depend on your budget, preferences, and intended use for your vehicle.
