If you want to see ram air in action then call a Pro Stock team and ask them for a pressure reading from the air box during a 1/4 mile run. Or call up a NASCAR team and ask them the same info. Or to make it simple call Dave Braswell and ask him how much air pressure a Pro Stock carb sees in the lights and how it changes the AF ratio.
