COMP Cams Nitrous HP retrofit camshafts are designed to work with your nitrous system to get more power from your engine. Their unique intake lobes allow your engine cylinders to fill better, for more complete combustion. Meanwhile, their exhaust lobes are spread to decrease overlap and ensure maximum scavenging of your combustion chamber. The bottom line is an increased power boost from your nitrous system without any loss of throttle response or torque in street applications.
