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 benefits of using ACL Race Series Main Bearings in my Holden V6, 3.8L engine?
ACL Race Series Main Bearings are designed for high-performance applications, providing enhanced durability and reliability under higher RPM conditions. The high strength overlay plate and hardened steel backs ensure better support and longevity, while the 3/4 grooving optimises oil supply to critical areas.
Do I need to modify my engine block to fit these main bearings?
Typically, these main bearings are designed to fit standard specifications for the Holden V6, 3.8L engine. However, it's essential to check for proper clearance and fitment, as machining or line boring may be required depending on your specific engine build and tolerances.
What should I consider regarding oil clearance when using these main bearings?
Oil clearance is crucial for the performance and longevity of the bearings. It's recommended to consult the manufacturer's specifications and ensure that the clearances are set according to your engine's requirements. This will help maintain adequate oil flow and prevent premature wear.
Are these main bearings suitable for both street and race applications?
Yes, ACL Race Series Main Bearings are engineered for both street and race applications. However, their performance characteristics make them particularly well-suited for high RPM and demanding conditions, so ensure your engine is appropriately built and tuned to maximise their potential.
What is the recommended installation procedure for these main bearings?
When installing ACL Race Series Main Bearings, ensure that the surfaces are clean and free from debris. It's advisable to use assembly lubricant on the bearing surfaces and follow the manufacturer's torque specifications for the main caps to ensure proper seating and alignment.
