When it comes to maximizing the performance of LS and Coyote engines, upgrading the camshaft and valve train components is crucial for achieving over 550 horsepower. These modifications not only enhance power output but also improve engine efficiency and responsiveness. In this article, we will explore some of the top camshaft and valve train upgrades available for both LS and Coyote engines.
Understanding LS and Coyote Engines
The LS engine family, originally developed by General Motors, has become a popular platform for performance enthusiasts due to its lightweight design and robust capabilities. On the other hand, the Ford Coyote engine, introduced in the Mustang GT, has also gained a strong following for its high-revving nature and advanced technology. Both engines can benefit significantly from camshaft and valve train upgrades.
Key Considerations for Upgrades
Before diving into specific upgrades, it’s important to consider a few key factors:
- Engine Goals: Define your horsepower target and intended use (street, track, etc.).
- Supporting Mods: Ensure your fuel system, intake, and exhaust can support increased airflow.
- Tuning: A proper tune is essential to maximize performance and reliability.
Top Camshaft Upgrades
Choosing the right camshaft is critical for achieving optimal performance. Here are some of the top camshaft upgrades for LS and Coyote engines:
LS Camshaft Upgrades
- Texas Speed Stage 2 Cam: This camshaft offers a great balance of power and drivability, making it suitable for both street and track applications.
- Brian Tooley Racing (BTR) Stage 3 Cam: Designed for high horsepower builds, this camshaft provides excellent lift and duration for maximum airflow.
- Comp Cams XFI Cam: Known for its aggressive profile, this cam is perfect for serious performance enthusiasts looking to push their LS engine to the limit.
Coyote Camshaft Upgrades
- Ford Performance Boss 302 Camshafts: These cams are designed to enhance the Coyote’s high RPM capabilities, making them ideal for track-focused builds.
- Steeda Coyote Stage 2 Camshafts: Offering improved lift and duration, these cams help maximize power without sacrificing drivability.
- Comp Cams Coyote Stage 3 Cam: This camshaft is engineered for maximum performance, delivering exceptional horsepower and torque gains.
Valve Train Upgrades
In addition to camshaft upgrades, enhancing the valve train components is essential for supporting increased lift and RPM. Here are some recommended upgrades:
LS Valve Train Upgrades
- Stronger Valve Springs: Upgrading to high-performance valve springs ensures proper valve control at higher RPMs.
- Pushrods: Consider using lightweight, high-strength pushrods to reduce deflection and improve performance.
- Retainers and Locks: Upgrading to titanium retainers can reduce weight and improve valvetrain stability.
Coyote Valve Train Upgrades
- High-Performance Valve Springs: Just like with LS engines, stronger springs are critical for maintaining valve control under high RPM conditions.
- Upgraded Pushrods: Opt for lightweight pushrods designed for high-performance applications to enhance reliability.
- Titanium Retainers: These can help reduce weight in the Coyote’s valve train, allowing for better performance at higher RPMs.
Installation and Tuning
Once you have selected your camshaft and valve train upgrades, the next step is installation. It is highly recommended to have these components installed by a professional to ensure proper alignment and function. After installation, a custom tune is essential to maximize the performance gains from your upgrades.
Conclusion
Upgrading the camshaft and valve train in LS and Coyote engines can significantly enhance performance and help reach the coveted 550+ horsepower mark. By carefully selecting the right components and ensuring proper installation and tuning, you can unlock the full potential of your engine and enjoy an exhilarating driving experience.
