by

The debate between LS and Coyote engines has been a hot topic among car enthusiasts, particularly those looking to build a powerful street cruiser. Both engine platforms offer unique advantages and challenges, especially when aiming for a build that exceeds 700 horsepower. In this article, we will explore the key differences, modifications, and considerations for building a 700+ HP street cruiser using Vortec and Whipple mods.

Understanding the LS Engine

The LS engine family, developed by General Motors, is renowned for its durability, lightweight design, and performance potential. It has become a favorite among performance builders due to its versatility and aftermarket support.

  • Durability: LS engines are built to withstand high horsepower applications.
  • Aftermarket Support: A vast array of performance parts is available for LS engines.
  • Weight: LS engines are lighter compared to traditional V8s, improving handling.

Understanding the Coyote Engine

Ford’s Coyote engine represents a modern take on the V8, featuring advanced technologies such as variable valve timing and a DOHC design. It has gained popularity in the performance community for its high-revving capabilities and robust power output.

  • High RPM Potential: Coyote engines can rev higher than traditional engines, providing a different power band.
  • Modern Technology: Features like direct injection enhance fuel efficiency and performance.
  • Performance Parts: A growing aftermarket supports Coyote engine modifications.

Key Modifications for 700+ HP Builds

Whether you choose an LS or Coyote engine, specific modifications are essential to achieve 700+ horsepower. Below are key modifications for both platforms.

LS Engine Modifications

  • Forced Induction: Installing a Whipple supercharger can significantly increase horsepower.
  • Upgraded Fuel System: A high-flow fuel pump and larger injectors are necessary to support increased power.
  • Headers and Exhaust: Upgrading to long-tube headers and a high-performance exhaust system improves airflow.
  • Engine Management: A custom tune is critical to optimize performance and reliability.

Coyote Engine Modifications

  • Supercharger Installation: A Vortec supercharger can provide the necessary boost for high horsepower.
  • Cold Air Intake: A high-performance intake system improves airflow and engine response.
  • Exhaust Upgrades: Upgrading to performance headers and exhaust systems enhances power output.
  • ECU Tuning: A proper tune is essential to maximize the benefits of modifications.

Comparing Performance: LS vs Coyote

When it comes to raw performance, both LS and Coyote engines can achieve 700+ horsepower, but their characteristics differ. Here’s a comparison of performance aspects:

  • Torque Delivery: LS engines typically provide a broader torque curve, making them feel more powerful in everyday driving.
  • High RPM Performance: Coyote engines excel in high RPM scenarios, providing a thrilling driving experience.
  • Weight Distribution: The lighter LS engines can improve handling dynamics, especially in performance builds.

Cost Considerations

Building a 700+ HP street cruiser requires a significant investment. Here’s a breakdown of potential costs associated with each engine:

LS Engine Costs

  • Base Engine: $2,000 – $5,000 depending on condition and specifications.
  • Supercharger Kit: $6,000 – $10,000 for a Whipple system.
  • Fuel System Upgrades: $1,500 – $3,000 for pumps and injectors.
  • Tuning: $500 – $1,500 for a custom tune.

Coyote Engine Costs

  • Base Engine: $5,000 – $8,000 for a new or used Coyote engine.
  • Supercharger Kit: $5,000 – $9,000 for a Vortec system.
  • Fuel System Upgrades: $1,000 – $2,500 for necessary components.
  • Tuning: $500 – $1,500 for a professional tune.

Conclusion
