Late Model Downforce....

I noticed that also, not sure what they are after but did notice it.

Could be to let the air over the left front to flow through. Could be to take air off the left front. Could be fake holes with black plastic behind em to see how many people copy not knowing why. ...

Downforce.

Just a quick follow up. I cut out the "Grill" area of my nose piece and installed some heavy duty 3/8" x 3/8" square wire. I went behind my nose piece and built an air box back to the shaker screen and no further. Car never ran over 220 degrees and had no effect to the handling of the car. Actually drove better this week than it has all year. I appreciate all of the hints and tips and the aero conversation was educational as well. Thanks guys.

Not fakes i seen them personally from about 1ft away

I would assume that they figured out a reason for lifting some air off the LF for some reason. When you are able to test that much you find little things that shave off just a little bit here and there. if it is worth anything I don't see it being beneficial to us weekend guys

Anybody have a picture of his car

[FlatTire]

Do they have any air ducts attached to these holes on the #1 car?

[DEKconsulting]

No ducts at all

[zeroracing]

I am struggling to come up with the reason DEK, I can see holes in other parts of the body but not there.

Their is a Go PRO in there filming everyone looking at them! They sit back at the shop and laugh it off. ..............Actually top secret stuff,info it will get around.... eventually.

Could be as the car yaws the air flow changes directions.That area is curved and could be speeding up air velocity thus creating lower pressure.Drilling holes helps eliminate this.
Theory #2 I have seen cars that put air under the car to create low pressure.These cars had ducting and belly pans tho

Probably better terms to describe it, but it eliminates the air coming around the nose and creating a vacuum effect in the left front wheel well area.

Next time you're running a test day at a 1/4 mile track, take the nose, the spoiler, and the right rear quarter panel off and see how she handles. But take it easy if the track has a wall. The good news is that when you hit it, you'll have less body damage to repair.
..

I dunno, Bobby Pierce runs without a RR quarter panel every week and runs pretty good. Not sure why he bothers putting new ones on anymore... His nose isn't much better. LOL
