While cam phasers provide tremendous efficiency benefits, they also present some limitations when it comes to performance camshafts. In turn, COMP Cams® has developed U.S. Patented Cam Phaser Limiter and Lock Kits for Chrysler Hemi 5.7L and 6.4L V8 engines. The limiter kits limit maximum cam phasing to 14 crank degrees (7 cam degrees) to provide the necessary piston to valve clearance when using larger aftermarket camshafts. Meanwhile, lock kits take all movement out of the phaser. Combining these performance modifications with more aggressive cam profiles will result in larger upper RPM gains without sacrificing any bottom end or mid-range performance. COMP Cams® Phaser Limiter and Lock Kits are one-of-a-kind, as they are the first phaser tools designed specifically for Hemi engines.
HHP Testing Results:
With our in-house test car, a 2009 5.7L VVT 6-Speed Challenger, we have dyno'd just this limiter by itself and seen a true gain of 22rwhp, STD Corrected, at the wheels. Tuning is required as this limiter will produce a check engine light without proper tuning. Contact HHP for all your tuning needs.
