Investing in cylinder head porting for your high-performance BMW engine enhances airflow efficiency for improved engine power, throttle response, and overall performance. By optimizing the intake and exhaust passages, porting reduces restrictions, allowing the engine to breathe better and generate more horsepower and torque.

We only use CNC equipment, ensuring that each port is machined to the exact same specifications, providing uniformity across all cylinders. This precision is crucial for maintaining consistent performance and efficiency.

Service Includes:

Total Disassembly, Cleaning, & Inspection

Our skilled technicians carefully disassemble and inspect each component for any damage, unusual wear, cracking, warping, etc. and perform leak, crack, and pressure testing to ensure the cylinder head is a good candidate for modifications.

During the cleaning process, techs are able to remove all built up contaminants, such as carbon deposits and oil sludge. Properly cleaned and prepared services are essential to ensure precise port and polish modifications, and establish a baseline for implementing performance modifications accurately.

Multi-Angle CNC Porting

Porting involves modifying the intake and exhaust ports of the cylinder head to improve the flow of air and fuel into the combustion chamber and the expulsion of exhaust gases out of the chamber.

The first step of this process involves assessing the cylinder head's current flow characteristics to identify any restrictions or turbulence. Then, material is carefully removed from the walls of the intake and exhaust ports to simultaneously enlarge them and improve their shape for optimal flow. The result is a smoother, more direct path for air and fuel into the combustion chamber, as well as a smooth, more efficient path for exhaust to flow out of the combustion chamber. 

Because we use CNC machining, we can ensure each port is exact and even across the cylinder head. This means airflow is balanced across all cylinders. Benefits of porting include increased airflow for more power and improved throttle response.
