Com to learn exactly how this ingenious system works. The function of the rocker arm is to be an intermediate actuator between the camshaft and the valves. The Hot Rockers system works by shifting the fulcrum pivot of the rocker arms as you drive. The auto manufacturers put a lot of design time into the valve train geometry which goes into their engines, which includes picking the proper Rocker Arm Ratio.
How can you make more horsepower by using the larger ratio rocker arms. For this reason, it is a common bolt on modification. Too much ratio will open the valves too quickly and can cause valve float at high rpm.

It also multiplies the loads on the pushrod and rocker arms, making the proper ratio critical. However, by just increasing the lift without increasing the Duration amount of time the valve is open, the power improvement is limited. How does changing rocker ratios affect the duration of the camshaft. Because the cam lobe is still the same, the point where the cam starts to move the lifter is still the same. We'll let you know all about them in an upcoming story. The same camshaft will now produce.
