COMP Cams is bringing the musclecar sound back, and it's nastier than ever! Few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. In an ongoing quest to provide you with the performance and sound that you demand, COMP Cams' engineering team proudly introduces the Thumpr Series hydraulic roller cam and lifter kits. They are designed for use in engines that were originally equipped with flat tappet camshafts. The lobe profile and grind characteristics of these Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap. They're designed to maximize the rough-idling characteristics of the cams, giving you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. They are available in three different grind profiles. Each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. Thumpr Series cam and lifter kits feature a cutting-edge hydraulic roller design that delivers a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.

COMP Cams HRT Stage 2 camshafts use the newest and most advanced lobe designs in order to produce some of the highest average power and torque available. The "Low Shock Technology" features lobe profiles designed to maximize horsepower while improving stability at higher engine speeds. These profiles are also easier on the valve springs, enhancing durability and reducing load loss. These new HRT camshafts receive the Micro Surface Enhancement (MSE) finishing process as a standard feature, which increases strength and performance by reducing surface peak roughness and provides a 250 percent improvement in the effective load bearing area, allowing for much higher loads.

COMP Cams Thumpr NSR modular 3-valve camshafts for Ford 4.6L/5.4L engines deliver an aggressive "thumping" exhaust idle and generous power gains in the middle and upper rpm range. They will turn your Ford 3-valve engine into a performance machine with a minimum of installation difficulty; they only require the addition of COMP Cams cam phaser limiter kits and computer tuning. These cam phaser limiter kits safely modify the factory variable cam timing (VCT) system, allowing for the use of aggressive camshaft lobe technology without sacrificing the benefits of the VCT. Choose between three unique cam designs—Thumpr, Mutha' Thumpr, and Big Mutha' Thumpr. Each delivers excellent horsepower gains and broad torque curves for your musclecar.

Ford 4.6L/5.4L modular 3-valve engines found in 2005 and 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?" COMP Cams XFI VSR Modular 3V (Valve Springs Required) Camshafts deliver a great power improvement over stock levels. These cams are the next step up from the COMP Cams 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 Cams 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 these camshafts is in the extensive dyno testing that allowed them 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 Cams XFI VSR Ford 4.6L/5.4L Modular 3V Cams optimize both mid and high rpm performance.

The COMP Cams XFI SPR Ford 4.6L/5.4L modular 3V (Springs & Phaser Mods Required) camshafts are the best way to achieve the most power and torque increases possible with the popular Ford Modular 3V engine. These designs are the next step up from the COMP Cams VSR (Valve Springs Required) cams. When compared to the VSR cams, the SPR cams offer additional mid-rpm power increases as well as substantial power gains in the higher rpm ranges. In addition to increases in horsepower, you can also expect another 800-1000 rpm of useable engine speed and an awesome sounding idle lope to match. To achieve this extra level of performance, lobe profiles and timing events were specifically designed to work with the factory variable cam timing (VCT) system cam phasers for all 2005 and newer Ford Modular 3V engines. These cam phasers were modified with the required COMP Cams Cam Phaser Limiter kit to restrict their movement to no more than 20 degrees. This simple modification gains additional piston to valve clearance, allowing for much larger cam designs. This results in cams that not only maintain low and mid-range power, but have incredible high rpm performance as well, all while maintaining the benefits of cam phasing. As noted by the COMP Cams engineering staff during extensive dyno testing, these camshafts provided the biggest power and torque improvements of any cam series they've ever tested in the Ford Modular 3V engine.
