What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What are the key features of the ACL Race Series Main Bearings for the Holden 3.6L V6?
The ACL Race Series Main Bearings for the Holden 3.6L V6 feature a high strength overlay plate with reduced thickness for improved performance, hardened steel backs for added durability, and increased crush to ensure a secure fit. They also include 3/4 grooving for optimal oil supply and consistent wall tolerances for precision.
Do I need to perform any specific machining when installing these main bearings?
Yes, it's crucial to ensure that the main bearing journals are properly machined and sized to match the bearings. Depending on the engine's condition, you may need to check for line boring and ensure that the main caps are properly aligned for optimal performance.
What RPM range are these main bearings designed to handle?
These ACL Race Series Main Bearings are engineered to endure higher RPM conditions, making them suitable for performance applications. However, the actual RPM capability will depend on the overall engine build, including clearances, tuning, and lubrication.
Are these bearings suitable for both street and race applications?
While the ACL Race Series Main Bearings are designed for high-performance use, they can also be used in street applications if the engine is built for higher RPM and performance. Always consider the specific engine setup and intended use when selecting bearings.
What should I check for during installation of these main bearings?
During installation, ensure that the bearing surfaces are clean and free of debris. Verify that the main journals are within the specified tolerances and that the bearings fit snugly without excessive play. Proper lubrication is essential before starting the engine to prevent damage.
