What Should You Look for in the Best LS Heads for a Blower Motor?
When searching for the best LS heads for a blower motor, several key factors should be prioritized to ensure optimal performance and compatibility.
-
Material: Aluminum heads are lightweight and dissipate heat well, making them a preferred choice for high-performance applications.
-
Valves and Ports: Look for larger intake and exhaust valves to improve airflow, enhancing power and efficiency. Heads with CNC-ported options are also beneficial for maximizing airflow.
-
Compression Ratio: The head’s design should complement the blower’s characteristics. A lower compression ratio generally works better with a supercharger to prevent detonation, so select heads that support this.
-
Camshaft Compatibility: Ensure the head allows for camshaft profiles that suit boost applications, as specific lift and duration can influence how the engine performs under boost.
-
Gasket Surface and Bolting: Flat, machined surfaces are crucial for creating a solid seal. Check for standard MLS (multi-layer steel) gaskets for peak performance.
-
Brand Reputation: Consider brands that are known for their reliability and performance, such as AFR, Trick Flow, and Edelbrock, using proven designs in blower applications.
Selecting LS heads that align with these criteria will enhance your blower motor’s performance and longevity.
How Do Specific LS Head Designs Affect Performance with a Blower Motor?
Valve Size: Opting for heads with larger valves can significantly enhance the intake and exhaust flow rates, making them ideal for supercharged applications. However, larger valves may require careful consideration of the cam profile to ensure optimal valve timing and clearance.
Combustion Chamber Design: A well-designed combustion chamber can promote complete combustion, essential for maximizing the efficiency of a boosted setup. Features like a quench area can help minimize detonation risks, which is particularly important in high-boost scenarios.
Material Composition: Cylinder heads made from aluminum are lighter and provide excellent thermal conductivity, which is beneficial for cooling in high-performance applications. However, iron heads may offer better durability under extreme conditions, making the choice of material critical based on the intended use of the blower motor.
Rocker Arm Geometry: Proper rocker arm geometry ensures that the valves open and close smoothly and efficiently, which is crucial for maintaining high RPMs and maximizing airflow. Any misalignment can lead to poor performance or even valve train failure, making it essential to select heads that accommodate the correct rocker setup for blower applications.
What Performance Gains Can Be Achieved by Using High-Boost LS Heads?
High-boost LS heads can significantly enhance performance, particularly when paired with a blower motor. The benefits stem from improved airflow, combustion efficiency, and increased power output. Here are some key performance gains that can be achieved:
-
Increased Horsepower and Torque: High-boost LS heads are designed to optimize airflow, allowing for a greater volume of air and fuel mixture to enter the combustion chamber. This translates to more power under high boost conditions, often resulting in gains of 100+ horsepower depending on the setup.
-
Better Cylinder Efficiency: These heads typically feature larger intake and exhaust ports that minimize restrictions. This leads to more efficient cylinder filling and improved scavenging of exhaust gases, thus enhancing overall engine efficiency.
-
Enhanced Engine Response: With improved airflow characteristics, high-boost LS heads can lead to sharper throttle response. The engine becomes more responsive across the RPM range, making it enjoyable to drive both on the street and the track.
-
Cooling Capabilities: Many high-performance heads offer superior cooling features. This helps manage the additional heat generated by boost, enabling sustained performance without overheating issues.
Selecting the right LS heads can ultimately unlock the potential of a blower motor setup, leading to a more powerful and robust engine performance.
