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 bore clearance for the BH64-10-STD pistons?
For the BH64-10-STD pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. However, always verify with your specific engine build and tolerances.
What compression ratio can I expect with the BH64-10-STD pistons?
The BH64-10-STD pistons provide a compression ratio of 10:1 when used with the specified 74.2cc head. Ensure your engine's overall setup supports this ratio for optimal performance.
What is the weight of the BH64-10-STD pistons and how does it affect performance?
The BH64-10-STD pistons weigh 488 grams. Lighter pistons can improve engine response and reduce stress on the connecting rods, but ensure your rotating assembly is balanced accordingly.
Do the BH64-10-STD pistons require any specific machining?
Yes, the BH64-10-STD pistons may require specific machining for proper fitment, including checking bore size and ensuring correct ring gap settings. Always consult with your engine builder for precise requirements.
What is the pin size for the BH64-10-STD pistons?
The BH64-10-STD pistons use a pin size of 0.927" x 2.250". Ensure your connecting rods are compatible with this pin size for proper fitment.
