COMP Cams Thumpr Hydraulic Flat Tappet Camshafts
COMP Cams is bringing the musclecar sound back, and it's nastier than ever! Few things grab our attention at a car show or cruise-in like a thumping, high performance idle. In fact, one of the most frequent questions from customers is, "What camshaft will give my car that mean-sounding idle?" For the performance and sound you demand, COMP Cams engineers introduce the Thumpr camshafts—a new series of hydraulic flat tappet cams. The lobe profile and grind characteristics of Thumprs use a combination of early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap—to maximize the rough-idling characteristics of the cams. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in several grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range.

Kanter Engine Valves
Kanter engine valves provide tangible gains in an engine's power, efficiency, and lifespan by strategically improving how air and fuel enter and exit the cylinder. Engine valves are one of the engine's most critical components, as they must withstand extreme temperatures, pressures, hitting impacts and loads during their lifetime. Because the operating temperatures of the intake and exhaust valves are highly different, various materials, structures, and manufacturing methods are required and implemented for each type of valve. Kanter's valve lineup includes various processes, such as forging, machining, welding, nitriding, and specialty coatings, that provide strength and durability. Select the engine valves tailored for your application needs.
