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.

Turbosmart OPR T40 Oil Pressure Regulators
Many turbochargers are built around a bearing and oil pressure profile much lower than is seen by modern and high-performance engines. Feeding these turbochargers the appropriate oil pressure has always been challenging. Traditional methods to limit oil pressure have been with a restrictor aimed at reducing pressure, which also reduces flow. Turbosmart OPR T40 are true regulators allowing the target oil pressure of 40 psi to be achieved without compromising oil flow. This takes the guesswork out of the restrictor or feed and drain hose selection and ensures the oil going to the turbocharger never exceeds the manufacturer's tolerances, providing you with a rock-solid oil supply pressure within the manufacture's tolerances. Turbosmart OPR T40 regulators are available in black or blue, as well as a special edition all-black "sleeper" version. Select the one you like best. Features: * Fixed 40 psi configuration * -4 AN ports * 1/8 in. NPT gauge port
