Are you experiencing problems with your engine’s cam phaser? Perhaps you’ve heard about cam phaser limiters and lockouts but aren’t sure which one is right for you. In this article, we’ll explore the differences between cam phaser limiters and lockouts, their pros and cons, and how they can affect your engine’s performance.

Cam Phaser limiter vs lockout
These are two popular modifications that can improve the performance of your engine. But which one should you choose? Here is the main differences between them-
What is Cam Phasers
Before we dive into the differences between limiters and lockouts, let’s take a quick look at cam phasers. Cam phasers are components that adjust the timing of the camshafts in your engine. They allow the engine to adjust the valve timing for better performance, fuel efficiency, and emissions control. However, they can also cause problems if they fail or malfunction.
What is a Cam Phaser Limiter?
A cam phaser limiter is a device that limits the range of movement of the cam phaser. It is typically used in engines with variable valve timing (VVT) to prevent excessive movement of the phaser. This can help reduce engine noise, improve power and torque, and prevent engine damage.
How Does a Cam Phaser Limiter Work?
A cam phaser limiter is installed on the end of the camshaft and limits the range of movement of the phaser. This reduces the maximum advance and retard positions of the camshaft, which can help prevent engine damage and improve performance. Cam phaser limiters are typically made of aluminum or steel and can be installed in a few hours.
What is a Cam Phaser Lockout?
A cam phaser lockout is a device that completely disables the cam phaser’s movement. It is typically used in high-performance engines where precise valve timing is not as important as maximum power output. A cam phaser lockout can help improve low-end torque and overall power output, but it can also increase engine noise and reduce fuel efficiency.
How Does a Cam Phaser Lockout Work?
A cam phaser lockout is installed on the end of the camshaft and prevents the phaser from moving. This ensures that the valve timing is fixed, which can help improve low-end torque and power output. However, it can also increase engine noise and reduce fuel efficiency, as the engine is no longer able to adjust the valve timing for optimum performance.
Cam Phaser Limiter vs Lockout: Comparison Table
To help you better understand the differences between cam phaser limiters and lockouts, we’ve created a comparison table below:
| Features | Cam Phaser Limiter | Cam Phaser Lockout |
| Valve Timing | Adjusts valve timing within a limited range | Disables valve timing adjustments completely |
| Performance | Improves power and torque, reduces engine noise | Improves low-end torque and overall power output, increases engine noise |
| Fuel Efficiency | Can improve fuel efficiency | May reduce fuel efficiency |
| Installation | Can be installed in a few hours | Can be installed in a few hours |
| Cost | Moderate cost | Moderate cost |
Which One Should You Choose?
So, which one should you choose for your engine? It depends on your specific needs and goals. If you’re looking to improve power and torque while reducing engine noise, a cam phaser limiter might be the right choice for you. On the other hand, if you’re looking to maximize power output and don’t mind increased engine noise, a cam phaser lockout might be the better option.
Conclusion
By understanding the differences between these two options, you can make an informed decision about which one is right for your vehicle. If you’re not sure which one to choose, consult with a trusted mechanic or performance specialist who can help you weigh the pros and cons of each option.
