I have a question about how pulling air in through side scoops and into a sealed air box would be anything but positive pressure. I agree that the side scoops alone will actually flow air out as speed increases.
There seems to be a fine line between cold air induction and ram air. How much pressure does it take for a system to become a ram air system? I might try to get some figures on my system once it is installed, however I think a simple test with some yarn on the air scoop inlet will prove that it is forcing air in at highway speeds or less.
I have a set and as mentioned they will not be a ram air system ..but the one small detail we are leaving out is the Negitive Pressure created if they are tied directly into the air box / cleaner ... as Wil mentioned an 80 degree diffence .. there sure is HP to be gained ...
The yarn test was done by the Swedes ( I think) a few years back.
As Jack said, in order to get "Ram Air", the scoops need to be a considerable distance away from the the car. You will, however, benefit from "cold air" performance increase.
