I need a science project idea based on NASCAR racecar aerodynamics.?

May be...

Check out how they would run backwards.

show how roof flaps keep a car that is spun backwards from leaving the ground.

Show Restricter plates got faster then COT becuz Restricter went like 200mph+ and cot goes up to 180mph

ffff

Yeah start with the scale models in the wind tunnel than take it to the track and research drafting as opposed to clean air in the front then do some adjustments to the car lift it up a bit then take it lower to the ground each track you have to make different adjustments for. Its in the track bar adjustments.

Anything having to do with Cup or Nationwide NASCAR car body styles, something about the body style dimensions that could be compared on a scale size in a wind tunnel.
Any ideas on what I could do for a project?

demonstrate drafting

Do whether it would be possible to win a race in reverse (like Ricky Bobby did at his race).

Hope to help,
CP

Just show the difference between a "regular" passenger car and the COT.

Or use a model of the COT and a block of wood.shook on3 videos
