Ls vs Hemi Comparison: Achieving 800 Hp with Trick Flow and Edelbrock Upgrades

by

The debate between LS and HEMI engines has been a hot topic among automotive enthusiasts for years. Both engine types have their own loyal followings and unique characteristics. In this article, we will explore how to achieve 800 horsepower using Trick Flow and Edelbrock upgrades on both LS and HEMI platforms.

Understanding LS and HEMI Engines

Before diving into the upgrades, it’s essential to understand the fundamental differences between LS and HEMI engines. The LS engine family originates from General Motors and is known for its lightweight design and high-revving capabilities. In contrast, the HEMI engine, developed by Chrysler, is recognized for its unique combustion chamber design that promotes efficiency and power.

LS Engine Characteristics

  • Lightweight aluminum construction
  • Versatile engine options and configurations
  • High-revving capabilities
  • Strong aftermarket support

HEMI Engine Characteristics

  • Iconic hemispherical combustion chamber
  • Robust torque delivery
  • Distinctive sound and performance
  • Strong heritage in motorsports

Achieving 800 HP: The Upgrades

To reach the impressive 800 horsepower mark, both LS and HEMI engines require significant modifications. The following sections outline the essential upgrades using Trick Flow and Edelbrock components.

Trick Flow Upgrades for LS Engines

Trick Flow is renowned for its high-performance components, particularly for LS engines. Here are some key upgrades to consider:

  • Trick Flow Cylinder Heads: High-flow heads can significantly improve airflow and power.
  • Intake Manifold: A performance intake manifold is crucial for maximizing power.
  • Camshaft: Upgrading to a performance camshaft can enhance the engine’s power band.
  • Fuel System: A high-flow fuel pump and injectors are necessary to support increased horsepower.

Edelbrock Upgrades for HEMI Engines

Edelbrock also offers a range of performance parts that can help HEMI engines reach the 800 hp goal:

  • Edelbrock Cylinder Heads: Upgrading to high-performance heads enhances airflow and combustion efficiency.
  • Intake Manifold: Edelbrock’s intake manifolds are designed to optimize performance for HEMI engines.
  • Performance Camshaft: A suitable camshaft can improve power output and engine response.
  • Fuel System: Upgraded fuel injectors and pumps are essential for handling increased fuel demands.

Comparing Performance: LS vs HEMI

With the appropriate upgrades, both LS and HEMI engines can achieve remarkable performance. However, there are notable differences in how they deliver power:

Power Delivery

LS engines typically produce power at higher RPMs, making them ideal for high-revving applications. Conversely, HEMI engines tend to deliver more torque at lower RPMs, offering a different driving experience.

Aftermarket Support

Both LS and HEMI engines enjoy strong aftermarket support, but LS engines have a broader range of parts available due to their popularity in the tuning community. HEMI enthusiasts can still find quality components, but options may be more limited.

Conclusion

Achieving 800 horsepower with LS and HEMI engines is entirely possible with the right upgrades. Trick Flow and Edelbrock offer excellent components to help enthusiasts reach their performance goals. Ultimately, the choice between LS and HEMI comes down to personal preference and the desired driving experience.
