COMP Cams developed the process of ion nitriding for camshafts, or Pro Plasma Nitriding. [9] This is a 36-hour process that uses pulsed nitrogen plasma in a vacuum controlled environment to embed chains of nitrogen ions into the camshaft surface approximately .008” - .010” deep, significantly hardening the surface.

This combination raised the compression from 9.5:1 to 10.0:1. The L33 also used a unique camshaft not shared with any other engine, with the specifications at .050 duration being: 193 duration, .482 lift, 116 LSA. As a result, power increased by 15 hp (11 kW), to 310 hp (230 kW) and 335 lb⋅ft (454 N⋅m).
A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.
The head, camshaft carriers, and timing chain cover are aluminum, and the sump is die-cast aluminum. [1] Although cogged timing belts were becoming popular among contemporary overhead cam designs, the Quad 4 uses timing chains to drive both camshafts, as well as the water pump. Engine accessories are driven by a single-plane serpentine belt.
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
