When it comes to building high-performance engines, enthusiasts often find themselves torn between two popular platforms: the LS and the Coyote. Both have their strengths and weaknesses, but when aiming for 700+ horsepower, especially with the addition of Edelbrock superchargers and forged internals, the decision becomes even more critical. This article will delve into the specifics of each engine platform, comparing their build options, performance potential, and overall value.
Understanding the LS Engine Platform
The LS engine family, originating from General Motors, has become synonymous with performance and reliability. Known for its lightweight aluminum construction and robust design, the LS platform is a favorite among tuners and builders alike.
Key Features of the LS Engine
- Aluminum block and heads for reduced weight
- Wide range of aftermarket support and parts availability
- High-revving capabilities with a strong bottom end
- Compatible with various forced induction systems
Understanding the Coyote Engine Platform
The Ford Coyote engine is part of Ford’s modular engine family and has gained a reputation for its performance potential and modern technology. With features like variable valve timing and a DOHC design, the Coyote is a strong contender in the horsepower race.
Key Features of the Coyote Engine
- DOHC design with four valves per cylinder for improved airflow
- Integrated variable valve timing for better performance across the RPM range
- Strong factory internals capable of handling high power levels
- Modern technology with a focus on efficiency and performance
Building for 700+ Horsepower
To achieve 700+ horsepower from either the LS or Coyote platform, specific modifications are necessary. Below is a breakdown of ideal build options for both engines, focusing on the use of Edelbrock superchargers and forged internals.
LS Engine Build Options
- Forged Internals: Opt for forged pistons and connecting rods to withstand the increased power and boost.
- Edelbrock Supercharger: Choose the Edelbrock E-Force supercharger kit for optimal performance and ease of installation.
- Camshaft Upgrade: A performance camshaft will enhance airflow and improve power delivery.
- Fuel System: Upgrade to high-flow injectors and a fuel pump to support the increased fuel demands.
- Exhaust System: A high-performance exhaust system will help reduce back pressure and improve overall efficiency.
Coyote Engine Build Options
- Forged Internals: Similar to the LS, forged pistons and rods are essential for reliability at high horsepower levels.
- Edelbrock Supercharger: The Edelbrock E-Force supercharger is also compatible with the Coyote, offering impressive gains.
- Camshaft Upgrade: A camshaft designed for forced induction will improve performance and throttle response.
- Fuel System: Ensure the fuel system is upgraded with larger injectors and a capable fuel pump.
- Exhaust System: A performance exhaust will enhance airflow and reduce restrictions.
Performance Comparisons
When comparing the performance of the LS and Coyote engines at 700+ horsepower, several factors come into play, including tuning, weight distribution, and vehicle application.
Power Delivery
The LS engine tends to deliver power in a linear fashion, making it suitable for a variety of applications, from street to track. In contrast, the Coyote engine, with its advanced technology, can provide a more aggressive power band, especially at higher RPMs.
Weight and Balance
The LS engine is generally lighter, which can improve vehicle handling and acceleration. However, the Coyote’s DOHC design allows for a lower center of gravity, which can enhance stability during high-speed maneuvers.
Value Considerations
Cost is always a factor when building high-performance engines. The LS platform typically has a lower initial investment due to the abundance of used engines and parts. Conversely, the Coyote engine, while potentially more expensive, offers modern technology and efficiency that can justify the investment in the long run.
Initial Costs
- LS engines can often be found at lower prices in the used market.
- Coyote engines may require a higher upfront cost but offer advanced features.
Long-Term Investment
- LS engines have a vast aftermarket support, making parts readily available and affordable.
- Coyote engines may have higher reliability and efficiency, potentially saving money on fuel and maintenance.
Conclusion
Choosing between the LS and Coyote platforms for a 700+ horsepower build with Edelbrock superchargers and forged internals ultimately depends on personal preference, budget, and intended use. Both engines offer exceptional performance potential and can be tailored to meet the demands of high-performance applications. By weighing the benefits and drawbacks of each platform, builders can make an informed decision that aligns with their goals and aspirations in the world of automotive performance.
