Hey guys, Let's say we have two cams, and everything is identical (rpms, valves, springs, etc.), except the angle of lift on the cam. For simplicity, let's assume the lobe lifting edges are straight, and we want to achieve a lift of .75" (19 mm) with both cams. Cam #1 has a 60 degree angle of lift. Cam #2 has a 45 degree angle of lift. Question: I understand that cam #2 would open the valve slower, but do both cams require the same amount of total power to complete one lift cycle?
