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 options are available for the SC7206 pistons?
The SC7206 pistons offer two compression ratio options: 9:1 for standard applications and 9.5:1 for EVO VIII/EVO IX setups. Choose based on your engine's tuning and intended use.
What are the recommended machining requirements for the SC7206 pistons?
Ensure proper bore clearance is set according to your engine specifications. The pistons should be fitted with the correct ring gaps as determined by your engine builder to ensure optimal performance and reliability.
Can the SC7206 pistons accommodate high lift camshafts?
Yes, the SC7206 pistons feature deep valve reliefs that allow for the use of oversized valves and high lift camshafts, making them suitable for performance applications.
What is the weight of the SC7206 pistons and how does it affect performance?
Each SC7206 piston weighs 283 grams. This lightweight design helps reduce reciprocating mass, which can improve throttle response and overall engine performance.
What type of wrist pins are included with the SC7206 pistons?
The SC7206 pistons come with standard wrist pins (part number 866-2500-18CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those seeking enhanced durability.
