ACL Race Series Performance Engine Bearings: Unleash Your Engine's Potential
The perfect blend of innovative design, advanced metallurgy, and top - notch engineering delivers exactly what high - performance drivers expect from trimetal engine bearings.
Key Features
- Built to handle high RPM conditions, ensuring reliable performance.
- High - strength overlay plate with reduced thickness enhances fatigue resistance.
- Hardened steel backs on rod bearings offer better support and retention in the housing.
- Increased crush improves bearing retention for a more secure fit.
- Eliminated flash plating on the bearing back boosts heat transfer and grip in the housing.
- Increased eccentricity compensates for bore distortion at high rpm and aids in oil film formation.
- 3/4 grooved main bearings optimize load - carrying area and oil flow to conrods.
- Tight wall tolerances help maintain consistent clearances.
- Enlarged ID chamfers on bearing edges accommodate large fillet radius on performance crankshafts.
What's the Maximum Power Rating of ACL Race Series Bearings?
The engine's power rating can be adjusted in multiple ways, each affecting the bearing load and stress. Here are some factors:
- Increasing red - line engine speed
- Boosting turbo or cylinder pressure
- Changing timing and cam profiles
- Using low - viscosity oils or high engine temperatures
- Modifying crankshaft, connecting rod, or piston design
- Altering cylinder dimensions
It's more realistic to consider the'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 engine upgrades, with a good balance of strength and forgiveness. Remember, 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 these ACL Race Rod Bearings is straightforward. First, make sure your engine is clean and free of debris before installation. When fitting the bearings, ensure they are properly seated in the housing and that the clearances are consistent, thanks to the tight wall tolerances. It's important to note that these bearings are for rod bearings only, so don't use them in other parts of the engine. For maintenance, regularly check the oil quality and level. Since the bearings are designed to handle high RPM conditions, using high - quality oil will help keep them in good shape. Avoid using low - viscosity oils or running the engine at extremely high temperatures for extended periods as this can increase the load on the bearings. If you plan to upgrade your engine's performance by increasing turbo boost or changing cam profiles, be aware that the bearing load will change. Keep an eye on the engine's performance and if you notice any unusual noises or vibrations, it might be time to inspect the bearings. Overall, with proper use and maintenance, these ACL Race Rod Bearings will serve your Honda/Acura engine well for a long time.
