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 Conrod Bearings in my VW/Audi engine?
ACL Race Series Conrod Bearings are designed for high-performance applications, offering enhanced durability and precision. They feature a high strength overlay plate and hardened steel backs, which provide improved strength and reliability under high RPM conditions. This makes them ideal for racing and high-stress environments.
Do I need to modify my engine to fit these conrod bearings?
While the ACL Race Series Conrod Bearings are designed for VW/Audi 1471/1588/1781cc engines, it's essential to ensure proper fitment. Depending on your engine's condition, you may need to check for correct clearances and potentially hone the big-end to achieve the necessary tolerances.
What is the recommended oil clearance for these conrod bearings?
The recommended oil clearance for ACL Race Series Conrod Bearings typically depends on the specific engine build and intended use. Generally, a clearance of 0.0015” to 0.0025” is common for performance applications, but always consult your engine builder for precise specifications based on your setup.
How do the features of these bearings enhance oil supply?
The ACL Race Series Conrod Bearings incorporate 3/4 grooving, which optimises oil supply to the bearings. This design helps maintain consistent lubrication, reducing friction and wear during high RPM operation, ultimately contributing to improved engine performance and longevity.
Are these bearings suitable for street use or only for racing?
While ACL Race Series Conrod Bearings are primarily designed for high-performance and racing applications, they can be used in street engines that require enhanced durability and performance. However, it's crucial to consider your specific driving conditions and engine setup when selecting bearings for street use.
