The Leading Edge of Valve Train Technology

Comp Cams Xtreme Energy series can be used in any street or street/strip application where both throttle response and top-end horsepower is desired. These camshafts are designed to take advantage of the latest improvements in valve train components and the newest developments in camshaft design. Their aggressive lobe design produces better throttle response and top end horsepower than other cams with the same duration @ .050'' lift, while delivering increased engine vacuum. We do not recommend the use of stock valve train components with these camshafts due to the aggressive lobe designs.

Features:

Quicker opening lobe profiles deliver increased responsiveness & more area under the lift curve

More vacuum allows an increase in duration for improved performance and assists power brakes

Excellent performance in street carbureted applications

Best performance with aftermarket intake manifolds, headers, lower gear ratios
