I know this subject has probably been beatin to death, but here goes.
I was speaking to another board member the other day, who brought up a point about AB mods that kinda made sense. Have any of these mods ever been tested in the real world, not on a dyno?
I'm sure that on a dyno the mod will work because your dealing with stagnate air and the box has not been pressurized with ram air. So it would seem that anything you do to increase airflow into a box that is not being pressurized, will make more HP.
But what happens at 190mph. Do any modifications to the airbox disturb airflow and maybe even hurt performance at speed.
I know that even minor changes in the way air flows into the intake system can effect power changes in a big way.
Just a thought.
