Please call for other Machining Services. FLOW TESTING Our flowbench is an extremely important part of our cylinder head production process. As we develop a head, we can obtain data on the volume and velocity of the air flowing through the various parts of the head. The testing is precise enough to allow us to see the airflow around sections of the perimeter of each valve in a head. Remember, a great head doesn't just produce good peak flow numbers... it's all about area under the curve. We can flow test any head, if you'd like to know how your heads stack up.
