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 BM4011-055 pistons?
For the BM4011-055 pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. However, final clearance should be determined by the engine builder based on specific application and tolerances.
What compression ratio can I expect with the BM4011-055 pistons?
The BM4011-055 pistons provide a compression ratio of approximately 10.3:1 when used with a 78cc cylinder head. Ensure that the overall combination of components is compatible for optimal performance.
What type of ring set is compatible with the BM4011-055 pistons?
The BM4011-055 pistons are designed to work with a 1/16 x 1/16 x 3/16 inch ring set. Ensure that the rings are properly gapped according to your specific engine requirements.
What are the valve relief specifications for the BM4011-055 pistons?
The BM4011-055 pistons feature two valve reliefs designed to accommodate typical valve sizes in a BB Chrysler engine. Verify that your specific cylinder head and camshaft combination will work without interference.
How much do the BM4011-055 pistons weigh?
The BM4011-055 pistons weigh 657 grams each. It's important to consider this weight in relation to your rotating assembly for proper balance and performance.
