My personal feelings regarding a ram air feed into the induction system,is that while it is a nice study, the reality is that very few Pantera owners will drive their cars in such a way a to benefit from such mods. Most of the benefit will come to those who push the engine to higher RPM'S and especially in 4th and 5th gear as you will spend proportionally more time in these gears.
We will have some actual data about the ram air system and the chart sometime in December or January. The calculations on the above chart are based on very small side scoops and not the typical elephant ear scoops that are more common. The elephant ear scoops have at least twice the surface area that mine have. My car will be used for the testing on a private local race track. My side window scoops are being fed into a sealed air box. The FAST XFI 2.0 fuel injection system shows 40 degree cooler air when the scoops are attached to the sealed air box vs when the scoops are not attached. When I built this system five years ago my goal was just cold air induction, although when it becomes a ram air system at some point, I won't complain about that. I certainly agree that driving wide open in 4th or 5th gear isn't something that I will be doing very often on public roads.
