Rather than find ways around the recent advances in GM engine technology, the engineers at COMP Cams have found a way to work with the innovations to produce a powerful line of cams for newer L92 engines. These COMP Cams XFI SPR GM Gen IV VVT camshafts feature four unique cam grinds that provide substantial gains in both torque and horsepower. The 2007 and later GM L92 engines utilize Variable Valve Timing (VVT) technology, which changes the timing of the valves while the engine is in operation. VVT is controlled via cam phasers, which are computer-controlled cam gears that automatically optimize camshaft timing based on current engine rpm. While this technology provides tremendous efficiency benefits, it presents a challenge when designing performance camshafts. This is due to the wide range of the valve timing movement, which causes piston-to-valve clearance. Using the COMP Cams cam phaser limiter kit restricts the range of cam timing movement from 50 degrees to 20 degrees. While still utilizing the efficiency benefits of the VVT technology, this modification provides the necessary valve clearance for larger, more serious performance camshafts with tighter lobe separations.
