The Straight Story: Part Two
To make the results repeatable, Joe allows the exhaust air temperature on the flowbench to stabilize at 100 degrees before he begins testing. In his view a round temp reading makes calculating flow much easier and eliminates implementing correction factors.
Flow is measured in percentages on the bench, and Alaniz later converts those percentages to cubic feet per minute numbers, or CFM. Then he compares those numbers to his own record of stock GS-R heads. The amount of air moving through the bench, regulated by various sized orifices and valve lift, determines maximum CFM. Alaniz has found that flow numbers at a lower valve lift usually relate to torque, while flow numbers at a higher lift tend to indicate peak horsepower. When all the head work is completed and the head is retested, this information is given to the customer in the form of a blueprint chart, which includes chamber volume, how much the head was milled and theoretical horsepower - typically a conservative estimate.
