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 Conrod Bearings for the Cosworth BDA?
The ACL Race Series Conrod Bearings (4B1060H) feature a high strength overlay plate with reduced thickness for improved performance, hardened steel backs for robust support, and increased crush to eliminate flash plating. They also have tight wall tolerances and oversize chamfers where applicable for optimal fitment.
What machining considerations should I keep in mind when installing these conrod bearings?
When installing the ACL Race Series Conrod Bearings, ensure that the conrod and crankshaft journals are properly machined to the correct specifications. It's crucial to check for proper clearance and fitment, as well as to ensure that the bearing surfaces are clean and free of debris before installation.
Are these conrod bearings suitable for high RPM applications?
Yes, the ACL Race Series Conrod Bearings are specifically engineered to excel under high RPM conditions, making them suitable for performance applications such as the Formula Ford Cosworth BDA. However, reliability will depend on proper installation, machining, and engine tuning.
How do I ensure optimal lubrication with these bearings?
The 3/4 grooving on the main bearings of the ACL Race Series Conrod Bearings ensures optimal oil supply for enhanced lubrication. It's essential to maintain proper oil levels and use high-quality oil to maximise the performance and longevity of the bearings.
What should I check for during the installation of these conrod bearings?
During installation, check for proper bearing orientation, ensure that the conrod and crankshaft surfaces are smooth, and verify that the bearing clearances meet the engine builder's specifications. It's also important to follow the manufacturer's guidelines for torque settings on conrod bolts.
