How Much Lift do 1.6 Rockers Really Add?

Published by Dustin Babich on

1.6 rockers can add up to 0.050″ lift to a valve. The additional lift provided by 1.6 rockers can improve your engine’s performance by increasing airflow into the combustion chamber, resulting in increased horsepower and torque.

Rocker arms are crucial engine components that not only ensure proper valve operation but can also have a significant impact on engine performance. The rocker arm ratio determines the amount of lift that the valve receives from the camshaft, making it a critical component in your engine’s design.

A rocker arm ratio of 1. 6 can help improve your engine’s performance by opening the valves more fully, letting more air and fuel into the chamber, which can lead to an increase in power and torque. Installing 1. 6 rockers is a relatively simple modification that can have a significant impact on your engine’s performance.

Introduction/Background

Rocker arms are a crucial component in the performance of internal combustion engines. They play an essential role in increasing the lift of valves, which ultimately enhances engine power. Rocker arms increase lift by altering the ratio between cam lobe lift and valve lift.

The lift of a 1. 6 rocker arm is 60% higher than that of a standard rocker arm. The lift changes the engine’s compression ratio, enabling more air and fuel to enter the combustion chamber, consequently increasing its power output.

This will depend on other factors such as engine size and the amount of airflow through the engine. Rocker arms’ lift ratios improve with higher lift profiles of the camshafts in the engine, and matching the correct camshaft with the rocker arms can have a significant impact on engine performance.

Understanding Rocker Ratios

Rocker ratios are a prominent topic in engine building. Understanding how these numbers apply to engine performance is crucial. In essence, rocker ratios are measures of how far the valve is lifted relative to how much the camshaft lobe has lifted the rocker arm.

These ratios are significant because they regulate airflow and fuel delivery, as well as the engine’s overall power output. Engines are designed with various rocker ratios, ranging from 1. 5 to 1. 8. Different ratios will influence engine performance differently.

For instance, higher ratios lead to longer valve duration, allowing for greater airflow and fuel delivery. In contrast, smaller ratios may create less horsepower but generate more torque. The impact of rocker ratios on engine power is significant and dependent on a range of factors, including the camshaft duration and lift, and the engine’s compression.

The Benefits Of 1.6 Rockers

1. 6 rockers are known to improve engine performance. These rockers increase valve lift, leading to improved airflow. A better airflow leads to more power, and the engine runs more efficiently. 1. 6 rockers have more lift than 1. 5 rockers, which offer a boost of around 6% in valve lift.

Comparing to stock rockers, 1. 6 rockers offer 11-15% more lift, depending on the motor setup. The higher lift gives racers and performance enthusiasts an added advantage. The increased lift also affects valve timing and can help provide gains in horsepower.

The duration of the valve opening also increases, providing more opportunity for the fuel and air to enter the engine. Overall, 1. 6 rockers are a great addition to any performance engine.

Factors To Consider Before Installing 1.6 Rockers

Before installing 1. 6 rockers, a few factors should be considered. Compatibility with other engine components is crucial. The increased lift can impact valve train stability and durability. It’s important to balance the increased lift with other modifications. One should also ensure that the pushrod length is correct.

Installing 1. 6 rockers can result in increased engine power, torque, and efficiency. However, if not done properly, it may cause engine damage. Therefore, it’s essential to consult an expert before installation. Overall, 1. 6 rockers can provide significant benefits to an engine’s performance if installed with care and consideration.

Remapping Tuning After Installing 1.6 Rockers

1. Installing 1. 6 rockers brings about changes in engine dynamics, which require remapping tuning. 2. Adjusting engine tuning to account for the increased lift is crucial. 3. With 1. 6 rockers, the engine power and torque can increase, but only by a marginal extent.
