Pistons are the backbone of any true hardcore racing engine and that’s where CP-Carrillo excels. CP's Engineering department started off analyzing the competition, gathering industry data and deciding to make the highest level of pistons, period. The heart and soul of their pistons are built through their extensive Engineering Department and resources. This department is made up of several factors that push them ahead of the competition; Reverse Engineering, Design Experience and Flexibility, Analysis and R&D. As in racing, it takes a lot to be number one. At CP-Carrillo, they have it all and are number one in piston design, enabling CP internal images to to come in first on race day.

Whether you're interested in creating the next drag queen, or are looking at beefing up your daily driver, CP Pistons has you covered. CP is proud to provide a large shelf catalog with options that you'd only see in a custom piston. Dual pin oilers are a standard in CP Pistons. This allows double the amount of oil to the wrist pin. Accumulator grooves are also equipped on each piston. This helps with ring seal; reducing ring flutter, and creating an improved downward force which results in better power increases. CP also puts Constant Pressure Grooves on their pistons to work with the gas ports to help clear carbon build up.

    3D Modeling
    Each forging is designed using an advanced 3D modeling software package and is qualified through a rigorous Finite Element Analysis entity. 3D modeling enables CP to check thicknesses and weights before manufacturing allowing us to produce the strongest and lightest part for your application.

    Quality
    CP has developed proprietary tooling, dedicated cutters and unconventional fixtures to ensure that each piston is produced to the highest quality. Their 5-axis machining techniques allow us to create any piston while our computerized electronic inspection equipment makes sure they manufacture parts to the tightest tolerances in the industry.

    At CP, all pistons are created equal
    Whether you are a professional racer or a weekend warrior, CP prides itself to giving you the best part possible for your applications. All pistons at CP are put through a demanding quality control system and precise computerized machining, ensuring that your piston is the best piston available.

    Anti Detonation Grooves (Contact Reduction Grooves)
    Grooves that protect the top ring by disrupting detonation waves. Also know as contact reduction grooves, these grooves limit the piston/cylinder contact during high temperature and RPM.

    Accumulator Grooves
    A V shaped groove machined in the 2nd ring land to collect excess blow-by between the top and second ring. This groove collects residual gasses during combustion and alleviates top ring flutter while increasing ring seal.

    CP groove
    Stands for Constant Pressure Groove. This groove works as a channel on the lower part of the top land that equalizes pressure to the back of the top ring groove.
    When used in combination with lateral gas ports, the CP groove helps keep gas ports clear of carbon build up. In addition, the CP groove prevents the top land from smudging into the top ring if the land rubs the cylinder bore.

    Double Pin Oilers

    In conjunction with CP's dual fed reservoir add twice the amount of oil from the cylinder wall to the wrist pin.

    Radius Domes
    Used to maximize quench while eliminating possible hot spots that promote detonation.

    Cam and Barrel
    Extensive research and development has been done to find the optimum skirt shape for each piston. Having the correct cam and barrel on a part promotes the following:

  • Tighter clearances
  • Less noise
  • Better ring seal
  • More power
  • Durability

    Depending on the forging and application, different cam and barrel profiles are utilized for maximum performance.
