Award Winning Piston Design – Dual Velocity Gas Ports by JE
Introducing JE Pistons' Dual Velocity Gas Ports: Revolutionizing Engine Performance
At the 2024 SEMA Show, JE Pistons unveiled their latest innovation—the Dual Velocity Gas Ports—which earned the prestigious title of Best New Performance-Racing Product of 2025.
Understanding Gas Ports
Gas ports are small holes drilled into the piston that allow combustion gases to flow behind the top piston ring. This redirected gas pressure pushes the top ring outward against the cylinder wall, creating a greater seal between the ring and cylinder. The tighter the seal, the more power your engine will make. Although it may sound like a minor alteration to your piston, gas ports can greatly increase engine performance and efficiency, without much added manufacturing time.
The Dual Velocity Gas Ports Advantage
Traditionally, gas ports are on top of the piston (vertical) or are drilled into the side of the piston near the top ring groove (lateral). JE Pistons' Dual Velocity Gas Ports combine both vertical and lateral designs, bringing positive gas pressure to the back side of the top ring without a gas port that will clog from carbon build-up. By placing the vertical path on the outer side of the piston, they eliminate the risk of carbon buildup blocking the flow, ensuring consistent performance.
Proven Performance Gains
In controlled dyno testing on a Honda CRF450R engine, JE Pistons compared traditional gas port designs, their Dual Velocity Gas Ports, and pistons without gas ports. The results showed a 2% increase in peak horsepower and torque when using the Dual Velocity Gas Ports.
Versatility Across Applications
The Dual Velocity Gas Ports are not limited to specific engine types. Whether you're building a circle track engine, a 2,000hp drag racing big block Chevy, or anything in between, improved ring seal enhances performance across the board. JE Pistons has developed a process that allows them to add Dual Velocity Gas Ports to any piston they offer, be it a shelf part or a custom design
JE Pistons' Dual Velocity Gas Ports represent a significant advancement in piston technology, offering enhanced ring sealing, increased power output, and broad application versatility. This innovation underscores JE Pistons' commitment to pushing the boundaries of engine performance.
