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 BF6020-040 pistons?
The BF6020-040 pistons are designed to achieve a compression ratio of approximately 9.4:1 when used with a 60cc TFS Twisted head. However, final compression will depend on actual head gasket thickness and any machining done to the block or heads.
What type of ring thickness do the BF6020-040 pistons use?
These pistons utilise a ring thickness of 1.5mm for both the top and second rings, and a 3.0mm oil ring. Ensure proper clearance is set for optimal performance.
What is the pin size for the BF6020-040 pistons?
The BF6020-040 pistons feature a pin size of .927 inches with a length of 2.500 inches. Make sure to verify compatibility with your connecting rods.
Are there any specific machining requirements for the BF6020-040 pistons?
When installing the BF6020-040 pistons, ensure that the bore clearance is set correctly according to the engine builder's specifications. Additionally, check that the ring gaps are appropriately set for your application.
What is the weight of the BF6020-040 pistons?
The BF6020-040 pistons weigh 438 grams each. This weight should be considered when balancing the rotating assembly for your engine build.
