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 SC7312 pistons?
The SC7312 pistons are designed for a compression ratio of 9:1. This is suitable for a balance of performance and reliability, especially when tuned for boost.
What is the weight of each SC7312 piston?
Each SC7312 piston weighs 365 grams. This lightweight design contributes to reduced reciprocating mass, which can enhance engine response.
What type of wrist pins are included with the SC7312 pistons?
The SC7312 pistons come with standard wrist pins (part number 827-2250-20CP1C) included at no additional cost. Upgraded and ultra-duty pins are also available for those seeking additional strength.
Are the SC7312 pistons compatible with high lift camshafts?
Yes, the SC7312 pistons feature deep valve reliefs that accommodate high lift camshafts and oversized valves, making them suitable for performance applications.
What machining considerations should I keep in mind when using SC7312 pistons?
When installing SC7312 pistons, ensure that the bore clearance is set correctly according to your engine's specifications. Additionally, check that the ring gaps are appropriately set for your application to prevent issues under high load.
