So my cooling system seems to do just fine when heading into the wind, and I do see some improvement in fuel consumption into the wind with the grill blocked off. However, with a 20-30 mph tailwind and 90*F, I don't think I am getting adequate flow through my radiator as I consistently see my coolant temps over 200*F which I am not comfortable with. I haven't had a problem per-se but it has gone as high as 212*, which I then rolled down a window and blasted the heater, I am NOT GOING TO DO THAT ALL SUMMER!
The grill block is coming off for afternoon drive home, though I think my partial belly pan/radiator scoop does help some and I will be pursuing a more appropriately engineered and permanent solution with ABS or fiberglass.

*What do ya'll think of a Detachable Nose Cone that would cover the upper grill, and hopefully channel high pressure air directly into the flux-capacitor? The top portion of this scoop/nose would continue the line of the hood to about 10-12" out front and be only as wide as the top of the lower grill opening. Could be made of High Density Foam and fiberglass over?
I couldn't look any worse than the 'Cuda RoadRunner....right.

I'm also dreaming of a Plexi or PolyC rear glass cover starting from the roof glass transition down to the edge of my low rise spoiler. Like a hatch for a coupe.

@Aerohead: That Aerotech I is the most beautiful shape I have ever seen on wheels, why in hell didn't they just do that in Aluminum and sell it? I'd have bought one.
