Frequently Asked Questions (FAQs)

1. Does connecting rods increase horsepower?

Connecting rods can increase horsepower in an engine. Stock connecting rods are designed to handle a certain amount of horsepower, but aftermarket performance connecting rods can handle significantly more horsepower. These upgraded rods allow for higher rpm and increased power output, providing a performance boost to the engine.

2. What does the connecting rod in high-speed engines have?

Connecting rods in high-speed engines often have the shape of an I-beam or an H-beam. The I-beam design offers greater load support and reduced deflection compared to the same amount of material in an H-beam design. Additionally, these rods have central holes for lubrication oil to pass through, especially in engines with oil-cooled pistons.

3. What is stronger, H-beam or I-beam connecting rods?

H-beam rods are generally considered to be the strongest design, assuming all other variables are equal. However, the overall strength and reliability of connecting rods depend on factors like material, weight, and cross-section. Both H-beam and I-beam rods can be strong, but H-beam rods can often handle higher compressive loads with less weight.

4. Which is better, H or I-beam connecting rods?

Both H-beam and I-beam connecting rods have their advantages. H-beam rods can handle higher compressive loads with less weight, making them suitable for high-performance applications. On the other hand, I-beam rods can be just as strong as H-beam rods and are often preferred for their ability to reduce piston weight and improve torque curve shape and combustion efficiency.

5. What is the advantage of longer connecting rods?

Longer connecting rods are commonly used in racing engines for several advantages. They help reduce piston weight, which in turn improves torque curve shape and combustion efficiency. Longer rods also require shorter and lighter pistons, which can push the ring pack higher on the piston. This configuration can have positive effects on engine performance and overall efficiency.
