When it comes to enhancing the performance of your engine, upgrading the camshaft can make a world of difference. A camshaft upgrade can unleash a surge of power, improve torque, and optimize engine performance. But with so many options on the market, how do you choose between COMP Cams and Brian Crower, two giants in the industry? In this article, we will delve into the science behind camshaft upgrades and compare the offerings from these two renowned manufacturers. By understanding the impact of camshaft upgrades on engine performance and considering factors such as intended usage, you can make an informed choice for your vehicle.


A camshaft is a critical component of an engine’s valve train system. It controls the opening and closing of the intake and exhaust valves, ensuring the smooth flow of air and fuel into the combustion chamber and the expulsion of exhaust gases. The design of the camshaft dictates the valve timing, lift, and duration, all of which have a significant impact on engine performance.

A camshaft upgrade involves replacing the factory camshaft with a higher-performance alternative. These aftermarket camshafts are designed to optimize valve timing and lift, allowing for greater airflow into the engine. By increasing the valve lift and duration, a camshaft upgrade can unlock additional power and torque.


When it comes to camshaft upgrades, COMP Cams and Brian Crower are two manufacturers that stand out in the market. COMP Cams, with a rich history dating back to 1976, has an extensive lineup of performance camshafts. They are known for their innovative designs, precise engineering, and rigorous testing processes.

On the other hand, Brian Crower, founded in 2002, has quickly gained a reputation for producing high-quality camshafts. They specialize in designing camshafts for import engines and are known for their attention to detail and performance gains.

Both COMP Cams and Brian Crower offer a wide range of camshafts for various applications, from street performance to full-blown racing setups. Their camshafts are compatible with a vast array of engines, providing options for enthusiasts of different backgrounds and preferences.


Camshaft upgrades have a profound influence on an engine’s performance characteristics. By altering valve timing, lift, and duration, these upgrades can significantly affect the power, torque, and overall drivability of the engine.

Increasing the duration and lift of the camshaft allows for more intake and exhaust airflow, resulting in improved cylinder filling and scavenging. This enhanced airflow leads to increased horsepower and torque across the engine’s operating range. Moreover, camshaft upgrades can enhance throttle response, making the engine more responsive to driver input.

However, it’s important to note that camshaft upgrades must be carefully matched to the engine’s other components, such as the intake and exhaust systems. A poorly chosen camshaft can negatively impact low-end torque, idle quality, and drivability. It is crucial to select a camshaft upgrade that complements the rest of the engine’s setup and intended use.


When comparing COMP Cams and Brian Crower camshafts, it’s essential to consider the specific characteristics of each brand’s offerings. COMP Cams offers a wide range of camshafts designed for various applications, including small block, big block, and LS-based engines. Their camshafts are known for their aggressive profiles, providing excellent top-end power.

Brian Crower, on the other hand, focuses on producing high-performance camshafts for import engines, including popular platforms like Honda, Mitsubishi, and Subaru. They offer camshafts with a range of profiles, catering to different power goals and driving styles.

While both COMP Cams and Brian Crower deliver reliable performance gains, it’s worth consulting expert advice or conducting thorough research to determine which specific camshaft suits your engine and intended usage best. Dyno testing, customer reviews, and expert opinions can provide valuable insights into the real-world performance gains of each brand’s camshafts.


Choosing the right camshaft upgrade depends on your engine’s intended use. If you primarily drive your vehicle on the street and seek improved performance during daily commuting or spirited weekend drives, a camshaft that maintains good low-end torque and drivability may be more suitable.

On the other hand, if you’re building a high-performance street machine or involved in competitive motorsports like drag racing, a camshaft that sacrifices some low-end torque for significant top-end power gains could be the ideal choice. Ensuring your engine’s other components, such as the intake, exhaust, and valvetrain, are properly matched to the camshaft is crucial to achieving optimal performance.

Ultimately, the right camshaft upgrade will provide the balance between low-end grunt, mid-range power, and top-end performance that best suits your specific driving style and goals.


When considering a camshaft upgrade, numerous factors should be taken into account to make an informed decision:

  1. Intended Usage: Determine whether the upgrade is primarily for street driving, occasional track days, or full-blown racing.

  2. Power Goals: Define the desired increase in horsepower and torque, taking into account the engine’s limitations and supporting modifications.

  3. Compatibility: Ensure the camshaft is compatible with the engine, valvetrain components, and supporting modifications.

  4. Valve Timing and Lift: Consider the camshaft’s duration and lift, as it determines the engine’s characteristics and powerband.

  5. Expert Advice and Reviews: Consult with experts, read customer reviews, and study dyno testing results to gain insights into real-world performance gains.

  6. Budget: Set a budget and choose a camshaft upgrade that fits your financial constraints while still delivering the desired performance gains.

By carefully considering these factors and thoroughly researching COMP Cams and Brian Crower camshafts, you can make an informed choice that maximizes the performance potential of your engine.
