When it comes to building a high-performance street machine, the choice of engine is crucial. Two of the most popular options among enthusiasts are the LS and Coyote engines. Both engines have their unique advantages and can be built to produce over 600 horsepower. In this article, we will explore the differences between the LS and Coyote engines and how to build a powerful street machine using Edelbrock and Ford Performance parts.
Understanding the LS Engine
The LS engine family, originally designed by General Motors, has gained immense popularity in the automotive community. Known for its lightweight design and robust performance, the LS engine offers a solid foundation for building high horsepower.
- Lightweight aluminum construction
- Wide range of aftermarket support
- High-revving capabilities
- Strong aftermarket performance parts
Understanding the Coyote Engine
The Ford Coyote engine, introduced in 2011, has quickly become a favorite among Ford enthusiasts. This modern V8 engine is known for its advanced technology and impressive power output, making it a strong contender for building a street machine.
- Modern DOHC design
- Variable valve timing for improved performance
- Robust power delivery
- Extensive aftermarket options
Comparing LS and Coyote Engines
Both the LS and Coyote engines have their strengths and weaknesses. Here, we will compare them based on several factors that are critical for building a 600+ horsepower street machine.
Power Potential
Both engines can be built to exceed 600 horsepower, but the methods and costs can vary significantly.
- LS engines can reach high horsepower with simple bolt-ons and tuning.
- Coyote engines require more extensive modifications to achieve similar power levels.
Weight and Balance
Weight distribution is essential for handling and performance. The LS engine is typically lighter than the Coyote, which can provide an advantage in weight-sensitive builds.
- LS engines are generally lighter, improving handling.
- Coyote engines provide a lower center of gravity, enhancing stability.
Aftermarket Support
Both engines have a vast array of aftermarket parts available, but the LS engine has been around longer, leading to a more extensive selection of performance parts.
- LS has a well-established aftermarket with numerous options.
- Coyote support is growing rapidly, but still lags behind the LS.
Building a 600+ HP Street Machine
Now that we understand the differences, let’s discuss how to build a 600+ horsepower street machine using either engine type. We will focus on the essential components and parts needed for the build.
Engine Selection
Choosing between the LS and Coyote engines is the first step. Your choice will influence the rest of your build.
- LS3 or LS7 for LS builds
- 5.0 Coyote for Ford builds
Performance Parts
Using quality performance parts is essential for achieving your horsepower goals. Here are some recommended components for both engine types:
- Edelbrock Supercharger: Ideal for both LS and Coyote engines, providing significant horsepower gains.
- Ford Performance Parts: Excellent choice for Coyote builds, including intake manifolds and camshafts.
- LS Performance Parts: For LS builds, consider headers, camshafts, and high-flow fuel injectors.
Fuel System Upgrades
To support high horsepower, you will need to upgrade your fuel system. This includes fuel pumps, injectors, and lines that can handle the increased demand.
- High-flow fuel pump
- Upgraded fuel injectors
- AN lines for better fuel delivery
Exhaust System
An efficient exhaust system is crucial for maximizing power. Choose headers and exhaust systems that reduce back pressure and improve flow.
- Long-tube headers for maximum flow
- High-performance cat-back exhaust system
Tuning and Final Adjustments
After assembling your engine with the selected parts, proper tuning is essential to achieve optimal performance. A professional tune will ensure that your engine runs efficiently and safely at high horsepower levels.
Dyno Testing
Before hitting the streets, it’s important to have your vehicle dyno tested. This will provide you with accurate horsepower and torque numbers, allowing for fine-tuning adjustments.
Real-World Testing
Once dyno testing is complete, take your street machine for a test drive. Pay attention to how it handles, accelerates, and performs under various conditions.
Conclusion
Building a 600+ horsepower street machine using either an LS or Coyote engine is an exciting project that can yield impressive results. By selecting the right parts from trusted brands like Edelbrock and Ford Performance, and focusing on proper tuning, you can create a powerful and reliable vehicle that stands out on the streets.
