CP Pistons | Forged Performance Pistons
Engineering the perfect combustion seal for high-horsepower builds. At Chicane Australia, we provide specialised supply for CP Pistons. Renowned for their advanced 2618-T6 alloy forgings and industry-leading CNC finishing, CP Pistons are the go-to choice for Australian engine builders pushing the limits of boost and RPM. We facilitate fast sourcing and reliable delivery across Australia for their entire forged piston catalogue.
The CP Advantage & Technical Features
CP Pistons (part of the CP-Carrillo group) has revolutionised the forged piston market with their X-Forging technology. This design utilises internal bracing and ribs to increase structural rigidity while significantly reducing weight. By moving the pin bosses inward, CP allows for the use of shorter, stronger wrist pins, reducing reciprocating mass without compromising the piston's ability to handle extreme cylinder pressures.
Our sourcing capabilities cover the primary CP Pistons performance range:
• X-Style Forgings: The pinnacle of their range, featuring "Forged Side Relief" (FSR) for reduced friction and maximum strength-to-weight ratio.
• Bullet Series: High-quality shelf pistons designed for popular platforms (LS, Barra, JZ, RB), offering premium features like 2618 alloy at a more accessible price point.
• Advanced Features: Every shelf piston now benefits from **Profiled Pin Bore Technology**, which uses a trumpet-shaped bore to reduce stress by up to 30% compared to traditional honing.
• Critical Tech: Includes Anti-Detonation Grooves (Contact Reduction Grooves) to protect top rings and Accumulator Grooves to maintain ring seal under high boost.
Based on the Central Coast, NSW, we assist you in selecting the correct bore size, compression ratio, and pin wall thickness for your specific build—from street-tuned turbo setups to 2000hp+ drag racing engines. We work closely with our supply network to ensure your CP hardware is sourced and despatched with professional care and speed.
CP Pistons FAQ
Why are CP Pistons made from 2618 alloy?
2618-T6 aluminium is a low-silicon, high-expansion alloy designed specifically for racing. Its superior ductility allows it to bend rather than shatter under extreme loads or detonation, making it the only choice for high-boost applications like the Ford Barra or Nissan RB26. While it requires larger cold-start clearances, it provides the ultimate in reliability.
What is an Accumulator Groove?
An Accumulator Groove is a V-shaped channel machined into the second ring land. It collects residual gases that blow past the top ring, reducing pressure build-up between the rings. This prevents "ring flutter" at high RPM, ensuring the top ring stays sealed against the cylinder wall for maximum power.
How quickly can you source CP Pistons?
We utilise a robust international and local supply network to provide the fastest possible turnaround. Most CP Bullet Series and popular shelf kits are sourced and despatched within a short timeframe for delivery across Australia.
