I don't know if this has be said already, but the difference in angle between the hood and the windshield is not as much on our cars as it was on old muscle cars. I think that this smaller difference in angle would make for less of a high pressure area when compaired to muscle cars of old.

Paul, is the area which is behind the firewall and below the wiper cowl area empty? If so, this would be perfect. My plan is cut an ovular shaped hole in the firewall area, attach a duct there, then connect via tubing to the air induction box. If that space is indeed empty, then there would be no issues with snow or rain water or any water being sucked into the intake.
As for the angle of the windshield, we have discussed this at length in other posts in the thread. My contention is that in NASCAR for example, they have steeply raked windshield, yet they all use cowl induction to feed rammed air into the carb. Many cars in road racing use a similar setup as well, especially when hood scoops are banned and the teams want to keep aero numbers good.
Car makers know that this particular area is a high pressure zone, hence the intake for the ventilation system there, not only on 8th Gen Civics, but all other cars as well. Unfortunately, I don't have any aero readings or pressure readings on an 8th Gen Civic. If anyone out there has aero/pressure info on our cars, feel free to chime in.
