CAP SECTION C-C In the world of racing, achieving the top spot requires exceptional effort and innovation—qualities that CP-Carrillo embodies fully. We lead the industry in piston and rod design, empowering our customers to secure victories on race day. PISTON FEATURES 1.160 Custom pistons and rods are the cornerstone of any elite racing engine, and that’s precisely where CP-Carrillo and Arias stand out. Our Engineering department began by meticulously analyzing the competition and industry trends, ultimately setting out to create the most superior custom pistons and rods available. The essence of our custom pistons and rods stem from the robust capabilities of our Engineering Department, which excels due to a combination of reverse engineering, seasoned design expertise, flexibility, and a strong focus on analysis and R&D. 1.335

U REVERSE ENGINEERING Our Reverse Engineering takes place in several different ways. We work from sample pistons, blueprints, chamber molds, 3D models supplied by a customer or a cylinder head. We employ advanced scanning technology to reverse H 3.18 .125

2nd groove CAM & BARREL The Cam is the shape around the skirt of the piston and the barrel is the shape from under the oil ring to the bottom of the skirt. Extensive research and development has been done to find the optimum skirt shape for each piston. These shapes have been found to seal up cylinders and reduce harmonics in the bore better than ever before.

In addition, the CP groove prevents the top land from smearing into the top ring if the land rubs the cylinder bore. A 0.7840 1.977 promotes the following: 1. Tighter clearances 2. Less noise 3. Better ring seal 4. More power 5. Increased durability ANTI DETONATION GROOVES (CONTACT REDUCTION GROOVES) Also known as contact reduction grooves, which limit the piston / cylinder contact during high temperature and high RPM. These grooves also protect the top ring by disrupting detonation waves. ACCUMULATOR GROOVE V-shaped groove machined in the 2nd ring land that adds to the volume between the top and second ring. This groove accumulates residual gasses from combustion which alleviates top ring flutter and premature second ring wear, improving ring seal. CP GROOVE CP Groove stands for Constant Pressure Groove.
