The automotive world is filled with passionate debates, and one of the most heated discussions revolves around the LS and Coyote engines. Both have their loyal followers, and when it comes to building a 700+ horsepower street beast, each has its own merits. In this article, we’ll delve into the specifics of both engine platforms, focusing on the use of Comp Cams and forged internals to achieve that coveted horsepower goal.
Understanding the LS Engine
The LS engine, a series of V8 engines produced by General Motors, has become a staple in the performance automotive community. Known for its lightweight design and robust performance, the LS platform offers a wide range of aftermarket support and tuning options.
Key Features of the LS Engine
- Aluminum block and heads for reduced weight
- Modular design allows for easy upgrades
- Strong aftermarket support for performance parts
Exploring the Coyote Engine
The Coyote engine, Ford’s answer to the LS, is a 5.0L V8 that has gained popularity for its high-revving capabilities and impressive power potential. It features a DOHC design, which allows for better airflow and efficiency compared to older pushrod engines.
Key Features of the Coyote Engine
- DOHC design for improved airflow
- High-revving capabilities for more power at higher RPMs
- Advanced technology with variable cam timing
Building a 700+ HP Engine
Both the LS and Coyote engines can be built to exceed 700 horsepower, but the approach and components used can differ significantly. Here, we will discuss some essential components and modifications necessary for both engines.
Essential Components for LS Build
- Forged Internals: Upgrading to forged pistons and rods is crucial for handling the increased power and boost.
- Comp Cams: Selecting the right camshaft is vital for optimizing performance. Comp Cams offers a variety of options tailored for LS engines.
- Aftermarket Intake Manifold: A high-performance intake manifold can significantly improve airflow and power output.
Essential Components for Coyote Build
- Forged Internals: Similar to the LS, using forged components is essential for reliability at high horsepower levels.
- Comp Cams: Coyote-specific camshafts from Comp Cams can enhance power and torque across the RPM range.
- Supercharger or Turbocharger: Adding forced induction can help achieve the desired horsepower levels more easily.
Tuning and Performance Optimization
Once the engine is built with the necessary components, tuning plays a crucial role in achieving optimal performance. Both LS and Coyote engines benefit from professional tuning to maximize horsepower and ensure reliability.
Tuning the LS Engine
Tuning an LS engine typically involves adjusting fuel maps, ignition timing, and other parameters to take full advantage of the upgraded components. Many enthusiasts turn to aftermarket tuning solutions for more control and customization.
Tuning the Coyote Engine
Coyote engines also require careful tuning, especially when adding forced induction. Utilizing a quality tuning platform can help ensure the engine runs efficiently and safely at higher power levels.
Comparing LS and Coyote Performance
When comparing LS and Coyote engines, several factors come into play, including weight, power delivery, and overall performance characteristics. Understanding these differences can help enthusiasts make informed decisions when building their street beast.
Power Delivery
The LS engine tends to provide a more linear power delivery, making it easier to manage on the street. In contrast, the Coyote’s high-revving nature can produce a more aggressive power band, which may be more suitable for track applications.
Weight Considerations
The lightweight design of the LS engine can offer advantages in terms of handling and overall vehicle dynamics. The Coyote, while heavier, compensates with its advanced technology and performance capabilities.
Conclusion
Both the LS and Coyote engines have their strengths and can be built to deliver over 700 horsepower. Choosing between the two ultimately comes down to personal preference, intended use, and the specific components selected for the build. With the right approach and quality parts, either engine can become a formidable street beast.
