What Makes an LS Blower Cam the Best Choice?
The duration of the camshaft determines how long the valves remain open during the engine cycle. Longer durations can improve peak power, especially at higher RPMs, but can also lead to a loss in low-end torque if not matched correctly with the supercharger’s characteristics.
The lobe separation angle is critical because it impacts how much overlap occurs between the intake and exhaust strokes. A narrower angle can provide more power at higher RPMs but may sacrifice idle quality, while a wider angle generally results in a smoother idle and better drivability.
A cam specifically designed for blower applications takes into account the unique pressures and flow dynamics introduced by the supercharger. This ensures that the cam can handle the added stress and continues to perform at its best under boost conditions.
Fuel compatibility is another important factor; a cam that works well with high-octane race fuel might not perform optimally with regular pump gas. Tuning for the specific fuel type used can lead to improved performance and efficiency.
Finally, driveability is essential for a street-driven vehicle. The best LS blower cam strikes a balance between high performance and everyday usability, ensuring that the car remains enjoyable to drive in various conditions.
How Do Lift and Duration Affect LS Blower Cam Performance?
The performance of an LS blower cam is significantly influenced by lift and duration, which are critical specifications that dictate how the engine breathes and performs under boost conditions.
- Lift: Lift refers to the distance the valve opens, affecting how much air and fuel can enter the combustion chamber. A higher lift cam allows for greater airflow, which can optimize the engine’s performance when paired with a supercharger, as it maximizes the amount of air forced into the engine.
- Duration: Duration is the amount of time the valve remains open during the engine’s cycle, measured in degrees of crankshaft rotation. Longer duration can improve high RPM performance by keeping the valves open longer, thus allowing for more air to flow, but it may sacrifice low-end torque, which is essential for daily drivability in some applications.
- Lift vs. Duration Balance: The right balance between lift and duration is crucial for achieving the best performance from an LS blower cam. A cam with high lift and moderate duration can enhance throttle response and power across a broad RPM range, making it a popular choice for those looking to maximize performance without sacrificing drivability.
- Impact on Boost: The interaction of lift and duration with the blower’s boost characteristics is vital. A cam designed for a specific boost level can optimize the engine’s efficiency and performance, ensuring the supercharger delivers air in a way that complements the cam’s specifications, enhancing overall horsepower and torque output.
- Valve Timing Events: The timing of the valve events, which is influenced by both lift and duration, plays a significant role in how effectively the engine can utilize the boost provided by a supercharger. Adjusting the timing can lead to improved performance under various load conditions, allowing for fine-tuning of the engine’s power band.

What Factors Should You Consider When Selecting an LS Blower Cam?
When selecting the best LS blower cam, several critical factors should be considered to ensure optimal performance and compatibility with your engine setup.
- Lift: The lift of a cam refers to how far the valve opens, which directly impacts airflow. A higher lift cam can improve performance at higher RPMs but may require specific valve springs and clearances, making it crucial to match the lift with your engine’s capabilities.
- Duration: Duration measures how long the valves remain open during the rotation of the camshaft. Longer duration can enhance power at higher RPMs but may sacrifice low-end torque, so it’s essential to find a balance that suits your driving style and engine setup.
- LSA (Lobe Separation Angle): The LSA determines the angle between the intake and exhaust lobes and affects engine vacuum and idle characteristics. A tighter LSA generally increases overlap, which can lead to a more aggressive sound and higher RPM power, while a wider LSA offers better low-end torque and drivability.
- Boost Compatibility: Since you’re using a blower, ensure the cam is specifically designed to work with forced induction. Some cams are optimized for boost, providing the right lift and duration to maximize the benefits of your supercharger or turbo, preventing issues like detonation or inadequate airflow.
- Idle Quality: The cam profile can significantly influence how your engine idles. If a smoother idle is important for daily driving or emissions compliance, consider a cam that maintains good vacuum and driveability, even when producing high horsepower.
- Spring Requirements: Different cams may have varying spring pressure requirements. Ensure that your valve springs can handle the cam’s lift and duration, as inadequate springs can lead to valve float or engine damage at high RPMs.
- Intended Use: Consider the primary use of your vehicle—whether it’s for daily driving, track racing, or street performance—as this will influence your cam choice. Different applications may prioritize low-end torque, high-end horsepower, or a balance of both, dictating the ideal cam specifications.
- Brand Reputation and Reviews: Researching brands and reading user reviews can provide insights into the reliability and performance of different LS blower cams. Established brands with positive feedback often indicate quality products that have been tested in real-world scenarios.
How Does Cam Profile Influence Boost and Power Output?
Duration: The duration of the cam determines how long the valves remain open during the engine cycle, which influences the total air-fuel mixture that can enter the cylinders. A cam with a longer duration can help increase power at higher RPMs, making it suitable for performance applications, but it might sacrifice low-end torque.
Lobe Separation Angle (LSA): The LSA is important because it determines how much overlap occurs between the intake and exhaust valves. A wider LSA can provide a smoother idle and increase low-end torque, while a tighter LSA can enhance high RPM performance, making it essential to match the LSA to the intended use of the engine.
Ramp Rate: A cam’s ramp rate affects how quickly the valve opens, which has implications for throttle response and drivability. A fast ramp rate can lead to better performance and quicker response, but if too aggressive, it can also lead to increased wear on the valvetrain components.
Overlap: Overlap can enhance the scavenging effect, allowing for better exhaust gas evacuation and drawing in more fresh air during the intake stroke. This is particularly beneficial in forced induction setups like blowers, as it can help achieve higher power levels, though excessive overlap can lead to a rough idle and potential tuning challenges.
What Are the Advantages of Upgrading to an LS Blower Cam?

What Are Common Misunderstandings About LS Blower Cams?
Duration is less important is a misconception that can lead to suboptimal results. While lift is a critical aspect, duration determines how long the valve remains open and affects the engine’s ability to breathe, which can enhance power across a wider RPM range if matched correctly with the supercharger’s characteristics.
All cams are compatible with all superchargers is an oversimplification that can lead to performance issues. Different superchargers require specific cam profiles to maximize airflow and boost efficiency, so selecting the right cam that complements the supercharger’s design is essential for achieving desired power levels.
LS blower cams are only for high RPM is a misunderstanding that can limit an engine’s potential. While these cams can shine at higher RPMs, many designs also enhance low-end torque, making them versatile for various driving conditions, especially in street applications where low-end responsiveness is crucial.
They require extensive modifications is a myth that can deter enthusiasts from considering a blower cam. In many cases, a properly chosen cam can be installed with relatively minor adjustments to the engine setup, allowing for performance gains without a complete rebuild.
