Head Porting Means More Horsepower

Head porting is a process for shaping or enlarging the intake and exhaust head ports to raise combustion. This increases power and torque dramatically. By enlarging the intake porting , there is greater air and fuel mixture for ignition.

The flow bench tests the flow of that air and fuel mixture and allows us to maximize that mixture to raise power. It also gives valuable information for correcting any issues such as portal design.

Porting the heads should also increase miles per gallon . The principle is that if the volume of air is increased , while the velocity is decreased, the air/fuel mixture burns more efficiently. The volume and velocity for each port depends on the engine and cylinder head design.

This one process can enable an engine to achieve much greater power at a price that will almost pay for itself in fuel savings.
