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 BBCRE5319-100 pistons?
For the BBCRE5319-100 pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. However, this may vary based on your specific engine build and intended use, so always consult with your engine builder.
What compression ratio can I expect with the BBCRE5319-100 pistons and 118cc heads?
The BBCRE5319-100 pistons are designed to achieve a compression ratio of approximately 15:1 when paired with 118cc heads. Ensure that your engine is properly tuned and that fuel quality is suitable for high compression applications.
What is the purpose of the gas ports in the BBCRE5319-100 pistons?
The gas ports in the BBCRE5319-100 pistons help improve ring seal and reduce blow-by by allowing combustion gases to pressurise the ring pack. This is particularly beneficial in high-performance applications where maintaining cylinder pressure is critical.
What is the weight of the BBCRE5319-100 pistons and how does it affect my engine?
The BBCRE5319-100 pistons weigh 712 grams each. This weight can influence engine balance and performance; lighter pistons can improve throttle response and RPM potential, but ensure your rotating assembly is balanced accordingly.
What type of ring thickness is used with the BBCRE5319-100 pistons?
The BBCRE5319-100 pistons utilise a ring thickness of .043" for the top and second rings, and 3.0 mm for the oil ring. Proper ring gap settings are essential for optimal performance and longevity.
