Achieving over 700 horsepower in your LS swap Z car is an exciting challenge that many automotive enthusiasts undertake. With the right combination of camshaft and intake components, you can unlock the full potential of your engine. This article will explore the best camshaft and intake combos, including the popular AFR 205cc heads paired with the LS7 cam.
Understanding the LS Engine Platform
The LS engine platform is renowned for its power and versatility. It is a lightweight, compact engine that can produce impressive horsepower numbers with relatively simple modifications. Understanding the components that contribute to power output is essential for any LS swap project.
Key Components for Achieving 700+ HP
- Camshaft
- Intake manifold
- Cylinder heads
- Fuel system
- Exhaust system
Camshaft Selection
The camshaft is one of the most critical components in your LS engine build. It controls the timing and duration of the valve openings, which directly impacts the engine’s breathing capability and power output. For a 700+ HP goal, consider the following camshaft options:
- LS7 Cam: Known for its aggressive profile and high RPM potential, the LS7 cam is a popular choice for high-performance builds.
- Texas Speed Cam: Offers various profiles designed to maximize horsepower while maintaining drivability.
- Brian Tooley Racing (BTR) Cam: BTR offers a range of camshafts that can help achieve your horsepower goals without sacrificing reliability.
Choosing the Right Intake Manifold
The intake manifold plays a vital role in directing airflow into the engine. An effective intake manifold can significantly improve performance, especially at higher RPMs. Here are some top choices:
- LS3 Intake Manifold: This manifold is a great option for maximizing airflow and works well with aftermarket camshafts.
- Fast 102mm Intake Manifold: Designed for high horsepower applications, this manifold offers excellent airflow characteristics.
- Holley Hi-Ram: Ideal for maximum performance, the Hi-Ram is suited for those looking to push the limits of their LS engine.
AFR 205cc Heads: A Perfect Match
When aiming for 700+ horsepower, the choice of cylinder heads is crucial. AFR 205cc heads are highly regarded for their performance capabilities and compatibility with LS engines. Here’s why they are an excellent choice:
- Flow Characteristics: The AFR 205cc heads provide superior airflow, which is essential for high horsepower builds.
- Lightweight Design: These heads are designed to minimize weight while maximizing strength and performance.
- Compatibility: They work exceptionally well with various camshaft profiles, including the LS7 cam.
Building the Right Fuel System
A robust fuel system is necessary to support high horsepower levels. Upgrading your fuel injectors, fuel pump, and fuel lines is essential for achieving and maintaining 700+ HP. Consider the following components:
- Fuel Injectors: Choose injectors rated for at least 80 lb/hr to ensure adequate fuel delivery.
- Fuel Pump: A high-flow fuel pump is necessary to supply the required fuel volume and pressure.
- Fuel Lines: Upgrade to larger diameter fuel lines to reduce restrictions and improve flow.
Exhaust System Considerations
An efficient exhaust system is vital for maximizing your engine’s performance. A free-flowing exhaust reduces back pressure and allows your engine to breathe better. Here are some options:
- Long Tube Headers: These headers provide the best performance by improving exhaust flow.
- High-Performance Cat-Back System: A quality cat-back exhaust system can enhance sound and performance.
- Mid-Pipes: Consider adding an X-pipe or H-pipe for improved exhaust scavenging.
Tuning for Maximum Performance
After installing your camshaft, intake, heads, and exhaust, proper tuning is essential to achieve optimal performance. A professional tuner can help you get the most out of your setup by adjusting fuel maps, ignition timing, and other parameters.
Conclusion
Achieving 700+ horsepower in your LS swap Z car is a rewarding endeavor that requires careful selection of components. By choosing the right camshaft, intake manifold, cylinder heads, and supporting systems, you can create a powerful and reliable setup. Whether you opt for the AFR 205cc heads and LS7 cam or explore other combinations, the key is to ensure all components work harmoniously together. Happy building!
