Why do folks "delete" the cam phasers in Mustang GT 4.6lt 3 valved engines???? Thanks in advance for any info!!!!!

 

Phaser limiters or even lockouts are required if you install performance cams that have a high enough valve lift/opening duration that would otherwise cause piston to valve contact. Full VCT functionality ensures that the torque band is as wide as possible with optimum driveability. Once you restrict or eliminate VCT function, those characteristics are compromised. Usually it's the idle quality, low rpm torque, and low rpm driveability that suffer.

Also on a Side Note If You Need New Phasers Use Genuine Ford as The Aftermarket ones are Junk They Say!

Although on a 5.4L Good Info on this Vid.
