When it comes to performance upgrades, both LS and HEMI engines have their unique strengths and weaknesses. Understanding the best supporting modifications for each engine type can help enthusiasts maximize power and efficiency. In this article, we will explore the most effective camshafts, intake systems, and forced induction options for LS and HEMI engines.
Understanding LS and HEMI Engines
Before diving into specific modifications, it’s essential to understand the fundamental differences between LS and HEMI engines. The LS series, developed by General Motors, is known for its lightweight design and high-revving capabilities. In contrast, the HEMI, produced by Chrysler, features a unique combustion chamber design that enhances power delivery and torque.
Best Supporting Mods for LS Engines
Cams
Upgrading the camshaft is one of the most impactful modifications for LS engines. A performance cam can significantly improve horsepower and torque by optimizing the engine’s airflow.
- Texas Speed Stage 2 Cam: Known for its aggressive lift and duration, this cam is ideal for high-performance builds.
- Brian Tooley Racing (BTR) Truck Cam: Great for daily drivers, providing a balance of power and drivability.
Intakes
An aftermarket intake manifold can enhance airflow, leading to increased power. LS engines benefit greatly from upgraded intakes that allow for better performance.
- Fast 102mm Intake: This manifold offers superior airflow and is perfect for high-horsepower applications.
- Holley Hi-Ram Intake: Designed for maximum performance, this intake is ideal for racing setups.
Forced Induction
Adding a supercharger or turbocharger can dramatically increase the power output of an LS engine. Forced induction allows for more air and fuel to enter the combustion chamber, enhancing overall performance.
- Whipple Supercharger: Known for its reliability and power gains, it provides a significant boost in horsepower.
- Turbocharger Kits: Options like the Precision Turbo kits can provide massive power increases with proper tuning.
Best Supporting Mods for HEMI Engines
Cams
Just like LS engines, HEMI engines can benefit from upgraded camshafts. A performance camshaft can enhance the engine’s breathing capabilities, leading to increased power.
- Comp Cams HEMI Cam: This cam is designed to improve performance without sacrificing drivability.
- Mopar Performance Cam: An excellent choice for those looking for a factory-backed performance upgrade.
Intakes
HEMI engines also see substantial gains from upgraded intake systems. A high-performance intake manifold can improve airflow and engine response.
- Fast Manifold: This aftermarket intake offers improved airflow and is a popular choice among HEMI enthusiasts.
- JLT Cold Air Intake: Enhances airflow to the engine, resulting in better throttle response and power.
Forced Induction
For HEMI engines, forced induction options like superchargers and turbochargers can provide significant power boosts. These systems allow for increased air and fuel intake, leading to higher performance levels.
- Procharger Supercharger: Known for its efficiency and power gains, it is a top choice for HEMI builds.
- Turbo Kits: Available from various manufacturers, turbo kits can provide extensive power increases with proper installation.
Conclusion
Choosing the right supporting mods for LS and HEMI engines can significantly impact performance. By upgrading camshafts, intake systems, and exploring forced induction options, enthusiasts can achieve remarkable power gains. Whether you own an LS or a HEMI, the right modifications will enhance your engine’s capabilities and provide an exhilarating driving experience.
