You need not be too overly concerned with flow numbers. Why? Because they understand flow is only one part of the equation that concerns, among other factors, inertia, swirl, tumble, and the injector trough. And yes, they do test and measure these factors.

For instance, if you take dye and run it through the stock MINI head and injectors you will see a 1" wide path in the cylinder; do that with the Wegner head and you will see a 3" wide path. This eliminates the "puddling effect" and enables you to make more power. It's not all about who shows the most flow at the top end but about how you get there.
