The Ultimate Guide to VCT Lockouts for Coyote Engines

Understanding VCT Lockouts

Variable Cam Timing (VCT) lockouts are essential for performance-focused builds. They eliminate cam phasing, allowing you to lock the camshafts at a fixed position for improved reliability and consistent performance. This is especially beneficial for high-horsepower Coyote engines.

Why Lock Camshafts?

• Reliability: Locking cams prevents the risks associated with VCT system failure, such as timing drift under extreme conditions.
• Precision Tuning: Fixed cam timing enables accurate tuning for specific performance goals.
• Simplified Setup: Removing the VCT system reduces complexity and potential maintenance issues.

Setting the Right Cam Centerline

Coyote engines feature four independent cams, allowing intake and exhaust centerlines to be adjusted separately for optimal performance. Here are some general guidelines:

• Intake Cams: Typically locked at a centerline between 110–114 degrees, balancing power and reliability.
• Exhaust Cams: Often locked at a centerline between 112–118 degrees, optimizing scavenging and high-RPM performance.
• Custom Tuning: Adjusting the centerline depends on your specific goals, such as increased low-end torque or top-end power.

Advanced users can fine-tune intake and exhaust cam timing independently to suit their build’s characteristics.
