Carrillo GAS-PORTS-VERTICAL CPP Vertical Gas Ports Piston Machining Option

The CP-Carrillo Vertical Gas Ports option is a precision piston machining upgrade available on custom CP-Carrillo piston orders. Vertical gas ports are drilled holes that run from the deck of the piston down to the back of the top ring groove, delivering a direct path for combustion pressure to enter the top ring groove area for maximum ring seal under load.

Key Features:

• Maximum Ring Seal: Vertical holes route combustion pressure directly into the top ring groove area, forcing the ring outward against the cylinder wall for superior sealing under power.
• Reduced Friction at Idle: When the engine is not under load, the top ring maintains normal tension, minimizing friction during low-load and off-throttle operation.
• Drag Race Proven: Vertical gas ports are most commonly specified for drag race and high-output performance applications where ring seal at peak cylinder pressure is critical.
• Pairs with Back-Cut Rings: Often used in conjunction with back-cut or reduced-radial-tension rings, which offer lower friction and enhanced performance characteristics.
• CP-Carrillo Custom Option: This machining feature is available as an add-on to custom CP-Carrillo piston orders and is performed in-house to exacting tolerances.

Note: In applications where carbon buildup is a concern, lateral gas ports may be preferred, as carbon deposits can potentially clog vertical gas ports over time. Consult a CP-Carrillo technical associate to determine which gas port configuration best suits your specific engine application.
