COMP Cams Chrysler Hemi Phaser Camshafts

COMP Cams Chrysler Hemi phaser camshafts utilize Variable Valve Timing (VVT) technology to maximize power and performance in stock and street/strip applications. The new Hemi engines from Chrysler are great power plants straight from the factory, with technology that allows the camshafts to move in real time. Instead of scrapping this advanced system, COMP Cams has embraced it with a new line of aftermarket Hemi-specific cams. The patent-pending Hemi phaser camshafts work with phaser limiters or locks to fully utilize Chrysler's Variable Valve Timing (VVT) technology, which allows them to pick up torque in the low end of the engine, while maintaining power up high. Made from a billet core, these hydraulic roller cams are engineered tough enough to handle 5.7L and 6.4L Hemi street/strip engines. Their unique, no-springs-required design maintains piston-to-valve clearance, while enabling high performance lobes utilizing VVT, making them perfect for late model Dodge Challengers, Dodge Chargers, Chrysler 300s, Jeeps, Dodge trucks, and Mopar crate engines with VVT. COMP Cams Chrysler Hemi phaser camshafts are available as both custom and three different off-the-shelf grinds, dependent upon engine type, for improved performance over OEM options. They will require the COMP Cams phaser limiter or lock kits to limit the degree of maximum cam phasing to 14 crank degrees (7 cam degrees) and they are available separately.

COMP Cams Godzilla Hydraulic Roller Camshafts

COMP Cams Godzilla hydraulic roller camshaft upgrades are designed to provide amazing drivability and throttle response, while producing increased torque across the entire RPM range with a significant horsepower bump with minimal effort. They're available in three distinct models: * Stage 1 NSR/NTR model: Utilizes the full phaser sweep for excellent mileage and optimized performance, without compromising durability. They requires no adjustment to the factory cam phasing or ignition timing without the need for a limiter. However, minimal ECU tuning may be required to meet the maximum potential. Testing with an optimized tune resulted in over 60 hp and 15 lbs.-ft. over stock with a much broader torque curve—impressive gains with minimal effort and zero compromise. * Stage 2 NSR model: Maintaining use of the phaser with a limiter kit allows these camshafts to also produce incredible horsepower. They offer maximum torque in the low- to mid-range for heavy vehicles and towing. Stage 2 cams deliver an increase of over 75 lbs.-ft. of torque at 3,000 rpm! They require a phaser limiter (P/N 5473). Testing with the phaser limiter kit resulted in gains of more than 75 hp over stock. One look at the torque curve produced by this camshaft will have your tires crying for mercy. * Stage 3 model: Godzilla Stage 3 camshafts are made for crate engines and engine swaps into lighter vehicles and those seeking maximum horsepower while still utilizing the phaser with a limiter kit. These cams bring the exhaust note that is worthy of the Godzilla name. They will produce well over 600 hp on pump gas! Awesome power can be expected, from 5,000 to 6,700 rpm with the valve spring kit (P/N 7230GCS-KIT) and a phaser limiter (P/N 5473). Testing with the phaser limiter kit resulted in gains of nearly 100 hp and 25 lbs.-ft. over stock. This much horsepower will make even Godzilla fly.
