Adjustable Camshaft Phaser Limiters for '11-'14 Ford 5.0 Coyote Modular 4 Valve

Comp Cams 5493 Adjustable Phaser Limiters for '11-'14 Ford 5.0 Coyote Modular 4 Valve

COMP CAMS Coyote  Cam Phaser Limiter Kits

Comp Cams cam phaser limiter kits are specially designed, computer-controlled cam gears that automatically optimize camshaft timing based on the current engine rpm Engine oil is pressure-fed to the phasers through passageways in the cylinder heads and cams. The engine computers control solenoids that adjust this oil flow into and out of the phasers' control chambers, creating the ability to retard the cams.

The Phaser Limiters and Adjustable Phaser Locks, which took home the honor of Best New Performance-Racing Product at the 2010 SEMA show, allow independent control over intake and exhaust centerlines, and eliminate piston to valve clearance issues that can occur when using larger aftermarket camshafts in 2011 Ford 5.0L Modular V8 engines.

The U.S. Patened COMP Cams Phaser Limiters for the 5.0L Coyote Modular V8 Engines physically limit maximum cam phasing to 20 crank degrees (10 cam degrees). Four separate phaser limiters, with the proper tuning software, allow the OEM computer to independently control intake and exhaust centerlines. Take full advantage of the benefits of Variable Valve Timing (VVT) when using aggressive aftermarket camshafts without needing to install custom pistons to eliminate valve clearance issues. For maximum performance, custom remapping of the cam phasing ECU control tables is required.

• Physically limit maximum cam phasing to avoid piston to valve clearance issues with aggressive cams
• Four phaser limiters or locks offer precise, independent control over intake and exhaust centerlines
• Phaser limiters physically limit cam phasing to 20 crank degrees (10 cam degrees) while allocating maximum intake advance and exhaust retard
• Allows use of larger, more aggressive aftermarket camshafts in 2011 Ford 5.0L Modular V8 engines
