I took Eddie's inspiration and put my camcorder mount to work. After I got everything set up it turned out the battery for the camcorder is totally shot. It had charged all day and had no power at all. This was not to stop me so I got out the inverter and plugged it into the 12v outlet. Here are pics of the set up:

taping the power supply to the car:

Here's the video:

Great job! Thanks!

now ya done it

 

[Sanford]

Hmmmm, now I'm thinking turky pan!

 

[NiceGuyEddie]

yaaaaaaaaahooooooooo!

for the first time in my life, i'm GLAD i got one-upped!

here is my first thread in case someone stumbles on this one first:

Great Video! Looks like a turkey pan might be in my future as well. Thanks for your effort.

Also, You're very trusting of that camera mount. Especially at 80mph! Is that mounted with just a suction cup?

I appreciate the feedback. The mount is pretty steady. I've had it over a 100 before and thought what would be the difference on the body behind me or the hood. Either way I loose the camera and mount. That's why I bought a cheap camera. The mount was pretty inexpensive. It came from Amazon for under $20.

Oh sure air goes into the scoop at 80 mph, but what about at 130 mph. I want to see that, before I am satisfied...:evil:

 

[2FAST4U]

WOW!! I'm truly impressed!!!

 

[Blackfish]

OK, I'm confused. What difference would a turkey pan make?

Go buy your own camera, mount, sign up for a track day and make sure to post the video. :stirthepot:

If I get the chance I'm definitely not shooting the hood scoop.

Got the image from Finish line:

It keeps the hot engine air out of the carb. You can get one from them.

How much air could flow through the hood scoop opening? C'mon math guru's.

 

[trevor]

the turkey pan isolates the cold air into the filter. The engine compartment air is hot.

Good job!!!!

I am wondering why at ~120 MPH the hood popped up on my Challenge car and settled back down below 100 MPH on the track - but I'm certainly not going to argue a test like this...

It must be what was posted in the other thread, lift like on an airplane wing or enough air went into the scoop and built up enough pressure @120 to lift the hood and lost the lift @ 100

Maybe we need to recreate your condition using a camera:wacko:

 

[George H]

Okay... maybe I'm being slow here, but was there some theory (for some reason) that an opening straight in the airflow over the body at 80mph wouldn't let air in?

Whats the reasoning behind that?

 

[Joe Camire]

Great work looked like air going in not out. Um kinda like it was designed to do. No low pressure there. Good job.

Ahh, that make sense. I knew what a turkey pan was, not why it was used. Thanks

The duct has nothing to do (effectively) with the lift generated by the shape of the body.

The hood was pulled up by lack of pressure above the hood, not by overpressure under the hood. The airflow into the scoop would be way higher than either, though. That's the difference between direct air pressure and the indirect reduction in pressure according to the Bernoulli principle over the surface of the hood.

George - Good point (re: Bernoulli) but if the negative pressure above the airfoil (body in this case) would hold true, are you then saying that the negative pressure stops somewhere just to the rear of the hood scoop opening and anything from that point forward would be a positive pressure?

The dead bugs on the fire wall of my car know the scoop works too.
