I was going down the interstate today and a pickup passed to my left and it had a contoured to the hood, bug screen. We know that when traveling some bugs hit the screen but the majority are swept up over the windshield. Would this not make the front of a pickup more aerodynamic by taking pressure off the cowl area and windshield, but it would add a small additional frontal area. I run in a production pickup class, would this be legal, I checked and a screen is available through both GM and Ford?

I believe that "frontal area" (when discussing aerodynamic drag force on a vehicle) refers to the overall cross-sectional area (as viewed from front or rear).

Not under SCTA rules. YMMV with ECTA and LTA. Texas - who knows, not many rules.

From what Ive read they hurt gas mileage so Id guess it would be a no on helping aero

99 percent sure that wouldn't fly with the ECTA either in production and I am doubtful it would allowed in any other class except the street legal T/O classes. I haven't had one on my vehicles in a long time as they usually interfered with the effectivenessmy wipers effectiveness but it was always fun driving with one in a snow squall and watching the flurries change path and float around in the dead zone a bit. I don't believe I ever got any measurable aero/mpg gains from one though.
