Frequently Asked Questions (FAQs)
1. How much HP do rocker arms add?
By swapping the stock rocker arms for higher lift rocker arms, you can increase total lift by around 6.7% and potentially gain 15 to 20 horsepower. Changing rocker ratios can have a significant impact on the performance of the engine.
2. What do performance rocker arms do?
Performance rocker arms are responsible for transferring the movement of the camshaft to the intake and exhaust valves of the engine. They ensure the proper opening and closing of the valves, which is crucial for the engine's overall performance and power output.
3. Do shaft rockers add horsepower?
Yes, shaft rockers can contribute to increased horsepower. They reduce valvetrain friction, leading to more power regardless of valve lift or rocker ratio. Shaft rockers also provide greater stability at high RPM, ensuring accurate valve timing events.
4. Are steel or aluminum rocker arms better?
Steel rocker arms are generally considered to be superior in terms of performance and reliability. While aluminum shaft rockers are suitable for race engine applications, they tend to fatigue faster compared to steel rockers. Steel rockers offer excellent durability and performance.
5. Do roller rockers actually make a difference in engine performance?
Roller rockers reduce friction and improve long-term reliability, but their impact on horsepower levels is not significant. The most significant impact on horsepower comes from changes in rocker ratio, rather than the type of rocker arm used.
6. How many miles do rocker arms last?
The lifespan of rocker arms depends on various factors. Under normal conditions with regular oil changes, rocker arms used on a daily driven engine with a stock valvetrain can last approximately 20,000-30,000 miles. However, if you run your engines for over 250,000 miles, you may need to replace aluminum rockers more frequently.
7. Do rocker arms increase duration?
Increasing the rocker ratio will also increase valve timing and duration. For example, changing from the stock ratio to a true 1.60:1 ratio can increase total valve duration by almost 20 degrees. This change in valve timing can have a significant impact on engine performance.
