Thats a lot of change in the nose area. I wonder if it's really that bad. I would hope not.

I've seen this airflow sheet in Jack Yamaguchis FC book. So it's been around since the prototype days of the FC. I know aerodynamics haven't changed since then.

Oh well, I'm rambling on.

actually, I think the longer the lines are, the more pressure there is i.e. long lines = lots of air pushing against that spot.

I was thinking, just put a large NACA duct in the front of the hood between the headlights.

guys......no ****...aero works good at 120+mph dont **** with it..this is from personal experience in the racing industry



a naca duct in between the headlight would cause a low pressure surge in the front or the car..that is why you will never see one set up like that on a production racing car..



just watch speedvision/espn2 and observe how the vents are setup/ mounted..and please dont look at nascar for aero advice
