CP High-Performance Forged Pistons - Driven by Technology

Designing the Finest Pistons

	Each new design is thoroughly researched and modeled on sophisticated 3-D software to ensure maximum strength and weight savings.	The model is then transferred to an advanced Finite Element Analysis program to optimize design parameters for maximum strength and durability.	A rapid prototype is then created to finalize design.	Advanced machining techniques enable CP to virtually create any shape on a piston. Strict quality control allows CP to hold the closest tolerances in the industry.	From their shop to your front door, CP prides itself on offering the best service in the industry.

CP Pistons Technical Features Fully CNC machined - Advanced machining techniques enable CP to virtually create any shape on a piston and allows CP to hold the closest tolerances in the industry. Balanced to +/- 1 gram - Properly balanced pistons are essential to high horsepower and high rpm applications. Accommodates high lift camshafts - CP pistons are already designed for high lift camshafts. Valve reliefs fit oversized valves - CP Pistons are designed to be compatible with other internal upgrades. Double forced pin oilers - Used with dual fed reservoir add twice the amount of oil from the cylinder wall to the wrist pin. Accumulator Grooves - V-shaped groove machined into the second ring land to collect excess gases during combustion and alleviate ring flutter. This allows CP Pistons to provide maximum ring seal and increasing vacuum. Forged from high strength 2618 Alloy - Using the highest quality materials and thoroughly researched designs ensures maximum strength and durability. Additional Information CP offers over 140 shelf part pistons from the Sport Compact shelf line with a wide range of bore sizes and compression ratios for the most popular engines. CP Pistons are designed with extensive research and devlopment in cooperation with some of the biggest names in motorsports. These pistons are engineered for maximum power. Pistons come with wrist pins, pin fitted, and locks (except for Subaru). Professional installation is highly recommended.
