New Product: COMP CamsR XFIT VSR Ford 4.6L/5.4L Modular 3 Valve Camshafts
Posted 10.1.2008 in New Products
The Ford 4.6L/5.4L Modular 3V engines found in 2005 & newer Mustangs are all the rage. So the question on everyone's mind
becomes, "How can I further improve the performance of these powerful engines?" The new COMP CamsR XFIT VSR Ford 4.6L/5.4L
Modular 3V (Valve Springs Required) Camshafts deliver a great power improvement over stock levels. These cams are the next
step up from the COMP CamsR NSR (No Springs Required) Cams and represent a major upgrade in power production. When compared
to the NSR, stock valve spring compatible cam series, the VSR cams offer a substantial power gain in the higher rpm ranges.
To achieve this, a high-lift design that requires a COMP CamsR Beehive Valve Spring upgrade was created to maximize power
within the limits of the OEM unmodified cam phasers. These new VSR camshafts are available for both naturally aspirated and
supercharged engines, with two levels available in each series; one designed for maximizing mid-range power and torque, while
the other maximizes top end horsepower.
The performance secret behind the COMP CamsR VSR Ford 3V Camshafts is in the extensive dyno testing that allowed Comp Cams
to determine precise cam timing events. Combining these optimized timing events with a high-lift lobe design offers
substantial improvements in both power and throttle response.
Designed to work flawlessly with the factory VCT, which is programmed to retard the cam timing above 4500 rpm, the new COMP
CamsR XFIT VSR Ford 4.6L/5.4L Modular 3V Cams optimize both mid and high rpm performance. For more information about the
COMP CamsR XFIT VSR Ford 4.6L/5.4L Modular 3V Camshafts or any other COMP CamsR products, call 1-800-999-0853 or
