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 SC7160 pistons?
The SC7160 pistons have a compression ratio of 11:1 for the F20C and 11.8:1 for the F22C. Ensure that your engine setup and fuel quality can support this compression for optimal performance.
What are the specific machining requirements for the SC7160 pistons?
When installing SC7160 pistons, ensure that the bore clearance is set according to your engine's specifications. Additionally, check ring gaps and adjust them as necessary for your application, especially if you're running higher boost levels.
Can I use the SC7160 pistons with high lift camshafts?
Yes, the SC7160 pistons are designed with deep valve reliefs to accommodate high lift camshafts and oversized valves. This makes them suitable for performance builds that require such modifications.
What is the weight of the SC7160 pistons, and how does it affect performance?
The SC7160 pistons weigh 327 grams each. Lighter pistons can improve engine response and reduce reciprocating mass, which is beneficial for high RPM applications. However, ensure that your engine is balanced properly with the full rotating assembly.
What type of wrist pins are included with the SC7160 pistons?
The SC7160 pistons come with standard wrist pins (part number 905-2250-15CP1C) included at no additional cost. For higher performance needs, you can upgrade to heavier duty pins as required.
