Wierd aero stuff

[MrQuick]

See what I mean about the grille opening? Do we need all of that?

Back when these cars were designed they did. Remember air was moved via engine driven fans that slowed down when the car was in traffic which would require more surface area and open air paths to cool.
Now we have cooling systems that are more efficient,fans that push more air and are electiclly modulated for different cooling needs.
This open area could now hinder aerodynamics. But here is the thing, is the car worthy of the effort? If your building an open road racer where the difference between 160 and 165mph is a 12" of frontal surface area,than a design change is warrented. I might look twice if this was a local raod coarse track car and speeds were lower.
Also the same efect can be made by moving weight around or increasing traction ratios.
