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 compression ratio do the SC7170 pistons provide?
The SC7170 pistons provide a compression ratio of 11:1 when used in the F22C engine. This ratio is suitable for performance applications, but ensure that your engine is properly tuned and that fuel quality is adequate to avoid knock.
What is the recommended bore clearance for the SC7170 pistons?
The recommended bore clearance for the SC7170 pistons typically ranges from 0.0015" to 0.0025". However, it's crucial to consult with your engine builder for specific clearances based on your engine's configuration and intended use.
Are the SC7170 pistons compatible with high lift camshafts?
Yes, the SC7170 pistons feature deep valve reliefs designed to accommodate high lift camshafts and oversized valves. This makes them suitable for performance builds aiming for increased airflow and power.
What type of wrist pins are included with the SC7170 pistons?
The SC7170 pistons come with standard wrist pins included at no additional cost. For applications requiring more strength, upgraded and ultra-duty wrist pins are also available.
What machining processes should be considered when installing the SC7170 pistons?
When installing the SC7170 pistons, ensure that the cylinder bores are properly honed to match the piston size and that ring gaps are set according to your engine's specifications. Additionally, balancing the rotating assembly is essential for optimal performance.
