head porting

Mini Coper S ported head 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 air 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.

The stock MINI Cooper cylinder head suffers from poor airflow as a result of small intake and exhaust ports and a very rough interior surface. Our cylinder head features larger ported and polished intake and exhaust ports which improve airflow dramatically.
