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 recommended clearances for the BHM5020 pistons?
For the BHM5020 pistons, it's crucial to follow the manufacturer's specifications for piston-to-cylinder clearance. Typically, a clearance of 0.0030" to 0.0040" is common for performance applications. Always verify with your engine builder to ensure optimal performance and reliability.
What type of rings come with the BHM5020 piston kit?
The BHM5020 piston kit includes RS1660-3875-0THG rings. Ensure to follow the specific instructions for setting the ring end gaps and installation to achieve the best performance and longevity.
Can I use the BHM5020 pistons with stock Harley Twin Cam components?
While the BHM5020 pistons are designed for enhanced performance, compatibility with stock components depends on the specific setup of your engine. Ensure that the compression ratio of 11.1:1 is suitable for your build and that your fuel quality can support it.
What is the weight of the BHM5020 pistons, and how does it affect my engine?
The BHM5020 pistons are designed to be lightweight, which helps reduce reciprocating mass and improve engine response. However, exact weight specifications should be checked with CP Carrillo for precise details. Balancing the entire rotating assembly is essential for optimal performance.
What machining processes are recommended for the BHM5020 pistons?
Before installation, ensure that the cylinder bores are properly honed to match the BHM5020 pistons. Additionally, check that the piston pin bores are clean and free of debris. Always consult with your engine builder for any specific machining requirements based on your engine's condition.
