The COMP Cams XR276HR Xtreme Energy hydraulic roller cam is aimed at high-performance street machines, providing stronger mid-range power and quicker valve events. It generally requires a higher-stall torque converter (2000+ rpm) and lower gearing to reach its potential, and may produce a choppy or noticeable idle. Best paired with upgraded induction and exhaust components.
