CNC Custom Head Porting with Benchflow Testing
This service is to optimize air flow in the cylinder heads.
Increasing air flow to an engine is one of the best ways to increase hp and torque. Head porting rids the intake and exhaust port chambers of irregularities, machine or casting flaws and obstructions. This dramatically improves airflow at low, mid and high valve lifts. When the surface is refinished, an even amount of airflow can enter and exit the heads. This results in an increased amount of airflow in the head that is even and consistent producing more hp and torque.
Butler LS uses a CNC machine that insures that all porting is precise and consistent from port to port. This is usually not consistent by hand porting.
After CNC porting is complete, we refine the porting based on the test results until optimum airflow is achieved.
