CP Piston Vertical Gas Porting (Per Piston)

If you're building a high-performance engine and looking to get the absolute most out of your pistons, consider adding vertical gas ports. This service, performed by CP Pistons, involves machining small ports into the piston crown, just above the top ring groove. These ports help to relieve pressure that can build up in the ring land area, which can otherwise lead to blow-by and reduced sealing. By venting this pressure, the top ring is better able to maintain contact with the cylinder wall, leading to a more efficient burn and potentially improved power output.

This is a popular modification for racing engines where every bit of performance counts. The process requires specialized equipment and expertise to ensure the ports are correctly sized and positioned for optimal results. It's a detail that can make a notable difference in the overall health and performance of your engine under demanding conditions.
