Comp Cams hydraulic lifters produce a "variable duration effect". At lower rpm this can reduce running duration by 6 to 10 degrees and decrease valve lift by .020 to .030 in. These "fast bleed" lifters work best with a cam that requires more compression ratio than the engine actually has. They help restore vacuum, cylinder pressure, and bottom-end performance. As rpm increases, lifters act more like normal hydraulic lifters. At 2500 to 3000 rpm they will produce the full duration and lift of the cam.

They should be used only if the engine's compression ratio is below the minimum recommended for the cam you have chosen. These lifters can cause "low speed detonation" if compression is too high. They are slightly noisier than standard hydraulic lifters (but not as noisy as a mechanical lifters) with a maximum rpm potential of 6,500 to 7,000 rpm. Comp Cams hydraulic lifters produce maximum performance with minimum noise. They offer increased vacuum, torque, and overall power with near stock valve train noise.
