What is Cylinder Head Porting? Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve the quality and quantity of the gas flow. Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing constraints. Porting the heads provides the finely detailed attention required to bring the engine to the highest level of efficiency. More than any other single factor, the porting process is responsible for the high power output of modern engines. This process can be applied to a standard racing engine to optimize its power output as well as to a production engine to turn it into a racing engine, to enhance its power output for daily use or to alter its power output characteristics to suit a particular application. Daily human experience with air gives the impression that air is light and nearly non-existent as we move slowly through it. However, an engine running at high speed experiences a totally different substance. In that context, air can be thought of as thick, sticky, elastic, gooey and heavy. Pumping it is a major problem for engines running at speed so head porting helps to alleviate this.

As with any simplification, it is not all true, but it's a heck of a good place to start. The number-one flow restriction in any engine is within the cylinder head. Get air to effectively pass these restrictions and you are good to go. It's a big subject to cover, so to chop it down to more manageable bites, we are going to apply five basic rules: 1. Locate the point of greatest restriction, and work on that first. 2. Try to let the air move the way it wants to, not the way you think it should. 3. Air is heavier than you think. Keep the port velocity up and avoid redundant cross-sectional areas. 4. Mixture motion (swirl or tumble, or a combination of both) is important-do not ignore it. 5. Shape is all-important-a shiny finish is not. Please allow a week for delivery inside USA (We do not proofread any ads submitted by members) |
