Review CP CARRILLO Pistons 103 Cu In 3.875 Bore 4.375 Stroke 7.667 Rod 10.75 fits CR

Introducing the CP-Carrillo BHM5080 piston series, designed for high-performance applications in naturally aspirated and forced-induction engines. These pistons are engineered to deliver exceptional strength, durability, and thermal efficiency, making them an excellent choice for serious enthusiasts and racers.

The BHM5080 piston series features a forged 2618-T6 aluminum alloy construction, ensuring superior strength and rigidity. The pistons are available in a variety of sizes, including a 103 mm bore diameter with a compression height of 3.875 inches, a 4.375 inch total height, and a piston pin bore of 7.667 inches. The piston pin is a CP-Carrillo 10.75 mm rod, crafted from 4340 chromoly steel for maximum strength and durability.

These pistons are designed to handle high compression ratios, making them suitable for high-performance applications. The crown design of the piston includes a dish height of 0.400 inches and a quench volume of 0.144 cc, optimized for efficient combustion and reduced engine heat. The piston skirts are fully machined and include an oil control ring groove to ensure proper ring sealing and minimize oil consumption.

The CP-Carrillo BHM5080 pistons are also designed with a proprietary coating process, which includes a high-temperature nickel-phosphorus coating on the piston crown and a silicon-aluminum-zirconia coating on the piston skirt. These coatings provide excellent thermal barrier properties, reducing piston-to-cylinder contact and minimizing the risk of detonation and engine damage.

Overall, the CP-Carrillo BHM5080 piston series offers exceptional strength, durability, and thermal efficiency, making them an excellent choice for high-performance applications in both naturally aspirated and forced-induction engines. These pistons are backed by CP-Carrillo's industry-leading warranty, giving you peace of mind and confidence in your engine build.
