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 is the recommended compression ratio for the BH575-950-020 pistons?
The BH575-950-020 pistons are designed to achieve a compression ratio of 9.5:1 when used with the '09-Present 5.7 Eagle head. Ensure that your engine's head and combustion chamber specifications align with this ratio for optimal performance.
What are the specific machining requirements for the BH575-950-020 pistons?
When installing the BH575-950-020 pistons, it's crucial to ensure the bore clearance is set correctly according to your engine's specifications. Additionally, verify that the ring gaps are appropriately set by the engine builder to accommodate the intended use and power levels.
Can I use the BH575-950-020 pistons with a different stroke or rod length?
The BH575-950-020 pistons are specifically designed for a 3.795" stroke and a 6.200" rod length. Using them with different stroke or rod lengths may lead to clearance issues and affect engine performance, so it's advisable to stick to the specified dimensions.
What is the weight of the BH575-950-020 pistons, and how does it affect performance?
The BH575-950-020 pistons weigh 420 grams. Lighter pistons can improve engine response and reduce reciprocating mass, but ensure that your engine's balance and overall rotating assembly are considered during installation to maintain reliability.
What type of valve reliefs do the BH575-950-020 pistons have?
The BH575-950-020 pistons feature two valve reliefs. This design is intended to provide adequate clearance for the valves in the Hemi V8 engine, which is essential for preventing interference during operation.
