Frequently Asked Questions (FAQs)
1. What is better cast or forged pistons?
Forged pistons are generally considered better for high-performance applications due to their strength and durability. Cast pistons, on the other hand, can be more brittle compared to forged pistons due to their higher silicon content. The silicon provides lubricity and limits heat expansion in the alloy.
2. How much HP can cast pistons handle?
Cast aluminum pistons, specifically hypereutectic ones, are best suited for engines producing up to approximately 600-650 horsepower in normally aspirated applications. Beyond that, forged pistons may be a better choice for higher horsepower levels.
3. What are the disadvantages of cast pistons?
Cast pistons have a porous structure, which makes them more vulnerable to damage when subjected to abuse. Additionally, while cast pistons are generally lighter, forged pistons offer greater reliability and strength, compensating for their slightly heavier construction.
4. Are cast pistons strong?
Cast pistons have a random grain structure due to the casting process, which can create weak spots and make them less inherently strong compared to forged pistons. Forged pistons, with their more controlled grain structure, are considered stronger and more reliable.
5. What is the max rpm for cast pistons?
For a standard road engine with cast pistons, it is generally recommended to avoid exceeding a piston speed of 3,500 feet per minute. As a guideline, caution should be exercised above 6,000 rpm to ensure the longevity and performance of cast pistons.
6. Are forged pistons the strongest?
While both forged and billet pistons have their strengths, forged pistons are generally considered stronger due to their better grain structure, resulting in more consistent material properties. However, the differences between the two are not significant.
