What is the compression ratio with these pistons?

These pistons have a 3.0cc dish volume, which results in an 11.3:1 compression ratio when used with compatible cylinder heads and gaskets. This is a common ratio for performance builds.

Are these pistons suitable for forced induction?

While designed for performance, the 11.3:1 compression ratio is generally on the higher side for heavy boost applications without proper tuning and intercooling. They are well-suited for naturally aspirated builds and moderate boost levels.

What does 'Not CARB approved' mean for shipping?

This means the pistons do not meet California Air Resources Board (CARB) emissions standards. Consequently, they cannot be legally shipped to California for use on vehicles registered in that state.

Product Details

Mahle is a well-known name in engine components, often supplying parts for original equipment manufacturers. This Mahle MS Piston Set is built for SBF 304 cubic inch engines, specifically those using the Coyote or Voodoo platforms. These pistons are designed to handle the demands of a performance engine build, offering a solid foundation for your rebuild.

This set features pistons with a 3.640-inch bore and a 3.650-inch stroke, paired with a 5.933-inch rod length. The 0.866-inch pin size is standard for many performance applications. Each piston has a 3.0cc dish volume, which contributes to a compression ratio of 11.3:1 when used with appropriate cylinder heads and gasket combinations. This compression level is suitable for naturally aspirated or forced induction builds seeking improved power output. The pistons themselves weigh in at 392 grams, a reasonable weight for forged components designed for durability.

This set includes eight pistons, enough for a complete V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a professional mechanic for specific installation requirements and compatibility with other engine components.
