About CP Pistons

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 them 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 them to create any piston while their 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.

CP Standard Features

Anti Detonation Grooves (Contact Reduction Grooves) are 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 Groove is 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 there dual fed reservoir add twice the amount of oil from the cylinder wall to the wrist pin.


X-Forgings are designed to minimize friction and reduce weight without compromising strength. With the use of bracing and ribs, the forging is configured by adjusting the weight balance between high and low stress areas. This design enables the use of a shorter pin for added strength and weight savings.


Radius Domes are 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:

1. Tighter clearances
2. Less noise
3. Better ring seal
4. More power
5. Durability
Depending on the forging and application, different cam and barrel profiles are utilized for maximum performance.
