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 SC7349 pistons?
For the SC7349 pistons, a typical bore clearance of 0.0015" to 0.0025" is recommended. However, this can vary based on the specific application and operating conditions, so it's best to consult with your engine builder for precise measurements.
What type of rings are included with the SC7349 pistons?
The SC7349 pistons come with high-performance CP rings, specifically designed for durability and optimal sealing. The ring thickness is 1.0 x 1.2 x 2.8mm, which is suitable for high boost applications.
Can the SC7349 pistons accommodate high lift camshafts?
Yes, the SC7349 pistons feature deep valve reliefs that accommodate high lift camshafts, making them suitable for performance builds that require increased airflow.
What is the weight of the SC7349 pistons, and how does it affect performance?
The SC7349 pistons weigh 302 grams each. Lighter pistons can improve engine response and reduce rotational mass, which can enhance overall performance, especially in high RPM applications.
What is the compression ratio of the SC7349 pistons, and how does it affect tuning?
The SC7349 pistons have a compression ratio of 9:1. This ratio is a good balance for both performance and reliability, but tuning must be adjusted based on fuel quality, boost levels, and overall engine setup to ensure optimal performance.
