Comparing Stock vs Built: Ls vs Coyote Engines Achieving 500, 750, and 1000+ Hp Benchmarks

by

The debate between LS and Coyote engines has been a hot topic among automotive enthusiasts, especially when it comes to achieving significant horsepower benchmarks. This article will explore the differences between stock and built LS and Coyote engines as they aim for 500, 750, and 1000+ horsepower levels.

Understanding LS and Coyote Engines

Both LS and Coyote engines have their unique characteristics and advantages. The LS engine, known for its lightweight design and robust aftermarket support, has been a favorite among performance builders. On the other hand, the Coyote engine, with its modern technology and efficiency, has gained popularity in the Ford community.

LS Engines Overview

The LS engine family was introduced by General Motors in 1997. It has become synonymous with performance due to its compact size, high power potential, and vast aftermarket support. Key features include:

  • Lightweight aluminum construction
  • Modular design for easy upgrades
  • High-revving capabilities

Coyote Engines Overview

The Coyote engine, introduced in 2011, represents Ford’s modern approach to performance. It features advanced technologies that enhance efficiency and power output. Key features include:

  • Dual overhead cam (DOHC) design
  • Variable valve timing (VVT)
  • High compression ratio for improved efficiency

Achieving 500 Horsepower

Both LS and Coyote engines can achieve 500 horsepower with various modifications. However, the approach and components used differ significantly.

Stock LS Engines

Stock LS engines, such as the LS1 or LS3, can reach the 500 horsepower mark with simple bolt-ons. Common modifications include:

  • Cold air intake systems
  • High-performance exhaust systems
  • Tuning and ECU remapping

Stock Coyote Engines

Stock Coyote engines, like the 5.0L variant, also have the potential to hit 500 horsepower with minimal upgrades. Key modifications include:

  • Upgraded intake manifold
  • Performance headers
  • Custom tuning solutions

Achieving 750 Horsepower

As we move towards the 750 horsepower benchmark, both engine types require more significant modifications to achieve this power level.

Built LS Engines

To reach 750 horsepower, a built LS engine typically requires the following enhancements:

  • Forged internals (pistons and rods)
  • Upgraded camshaft
  • Forced induction (supercharger or turbocharger)

Built Coyote Engines

For Coyote engines, achieving 750 horsepower often involves:

  • Forged engine components
  • Upgraded fuel system
  • Boost from superchargers or turbos

Achieving 1000+ Horsepower

Reaching the 1000+ horsepower mark is an ambitious goal for both LS and Coyote engines, requiring extensive modifications and tuning.

High-Performance LS Builds

High-performance LS builds capable of exceeding 1000 horsepower typically include:

  • Fully forged engine block
  • Custom turbo or supercharger systems
  • Advanced engine management systems

High-Performance Coyote Builds

For Coyote engines to reach over 1000 horsepower, builders often implement:

  • Upgraded cylinder heads
  • High-flow fuel injectors
  • Custom tuning for optimal performance

Comparison Summary

In summary, both LS and Coyote engines have their strengths and weaknesses when it comes to achieving high horsepower benchmarks. The choice between stock and built engines depends on the desired power level, budget, and personal preference.

Key Takeaways

  • LS engines are often more affordable to build for high horsepower.
  • Coyote engines offer advanced technology and efficiency.
  • Both engine types can achieve impressive power with the right modifications.

Ultimately, the decision between LS and Coyote engines will depend on individual goals and the specific application in mind. Whether aiming for 500, 750, or 1000+ horsepower, both engines can deliver thrilling performance with the right approach.
