ACL Race Series: High-Performance Engine Bearings
The perfect blend of design, metallurgy, and engineering offers what drivers look for in high-performance Trimetal engine bearings. These bearings are built to deliver top - notch performance and reliability.
Features
- Withstand high RPM conditions, ideal for high - speed racing.
- High - strength overlay plate with reduced thickness boosts fatigue properties.
- Hardened steel backs on rod bearings enhance support and retention.
- Increased crush ensures better bearing retention.
- Eliminating flash plating on the back improves heat transfer and grip.
- Increased eccentricity compensates for bore distortion and aids in oil film formation.
- 3/4 grooved Main Bearings optimize load - carrying area and oil flow.
- Tight wall tolerances help maintain consistent clearances.
- Enlarged ID chamfers accommodate large fillet radius on performance crankshafts.
Maximum Power Rating of ACL Race Series Bearings
The engine's power rating can be adjusted in multiple ways, each affecting bearing load and stress. Factors like increasing engine speed, turbo boost, changing timing and cam profiles, using low - viscosity oils, altering engine components, and modifying cylinder dimensions all impact bearing loading. Instead of a maximum power rating, it's more realistic to consider'maximum specific bearing load'. This is the maximum load spread over the bearing's projected area. Engine builders need to balance peak cylinder pressures with inertial loads. Generally, ACL Race bearings offer great flexibility for upgrading engine performance, with a good balance of strength and forgiveness. However, high load means shorter life. These bearings work well in street machines for normal engine life and in high - load 'Top Fuel' Dragster engines with short - term use.
Using ACL Race Main Bearings in your Honda/Acura engine is straightforward. First, make sure your engine is clean and free of debris before installation. Carefully place the bearings in their proper positions, ensuring they fit snugly. When starting the engine after installation, run it at a low speed initially to let the bearings settle in. As for maintenance, regularly check the oil level and quality. Using high - quality oil can significantly extend the life of the bearings. Keep an eye on engine temperature, as overheating can put extra stress on the bearings. If you notice any unusual noises or vibrations from the engine, it might be a sign that the bearings need inspection. Remember, these bearings can handle high - performance situations, but excessive loads will shorten their lifespan. So, if you're using your vehicle for regular street driving, you can expect a normal engine life. But for high - power racing, be aware that the bearings may need more frequent replacement.
