Basically what this is saying is that +.34 Psi @ 14.21 psi = + 17hp difference IN FAVOR of ram air. Which is good. However air is incompressible at speeds below 230mph IE: 14.7psi @ sea level + xx value.
So the ram air does work at bringing the PSI close to atmospheric pressure of 14.7, but will not cross that threshold until ground or airspeed reaches at least 230mph.
So myth confirmed, to a point. My apologies, as I should have said ram air to create boost, as boost is defined as 14.7psi + xx.
So, who said it created positive manifold pressure at common race speeds?
If it reduces the amount of vacuum in an intake then it has been successful. It does not require pressures above barometric.
Air inlets of different shapes and sizes will create different pressures. Combine that with different air demands of different engine/chassis/speed combos and you're all over the board.
As for JCC, don't try to make him think something he doesn't want to think. He has his own little ways of fighting for his preconceived notions. That's why I have him on ignore.
