My brain was interpreting the image with airflow from the left to right.
tru tried to set me right and it went right over my head.
Is this the Camaro with the aluminum nose which extends to almost ground level?
I need to know exactly which car this is.I apologize for the mix-up.( you guys need to keep a close eye on me!).

That's the one !

Yup ! It took me by complete surprise,
Not only does the car have the barn door flat front end, but it has the original misaligned moulding around the windshield, stock unshaved door handles, huge gaps everywhere ( look at the wheel wells ! ), no belly or skirts, etc !
It blew my mind, but it was tested in a wind tunnel by a guy that did the aerodynamics on the EV-1

( How ironic that the car has almost exactly the same Cd as the .19 of the EV-1 )

Ummm... this really needs expert explanation. If that Camaro can accomplish nearly the same Cd as the EV-1 looking like that, and a better number than a 2001 Insight, then... what the hell!

Here is the article : Car Aerodynamics - Hot Rod Magazine

I really think it would be great to invite the fellow that runs the tunnel there to join us for a few questions sometime !

I wonder if that tunnel would say my Coupe has .19 too?

Thanks

Still applies guys!

I posted a picture of the actual car in question and ask for any other ideas. I think a chin spoiler california civic's will be the first step, along with ditching the front plate bracket. Tire spats for front and rear tires will also be looked at. My question with the spoiler is, how low should I go. I dont wanna make it rediculously low and scrape it on everything, so would makin it just low enough to cover up the "ugly" under the bumper work?

The Camaro does apply, in principle.
If you take the chin spoiler alone, then generally lower is better. (See pic of Camaro above) Mine is 2" off the pavement and rubs everywhere. It is wide enough that it does the job of front tire spats as well. It made a large difference for me. I used the lawn edging as shown previously. It lasts about one year if you are rubbing constantly and is much more durable (because it will spring back when bent) than the Aluminum Sandwich.
Get the lawn edging and screw it in and see what happens, cut it down a bit and see how your mpg or coast distance changes, don't overthink this and don't worry about what people think as you expierement. Once you have a result you like, you will be able to live with the look. Everyone that asks me about my rear wheel skirts, I tell them that I think it looks goofy and I don't like the look, they then have a puzzled look, then I tell them it adds 3mpg and they begin to understand...

LOL, very true about the looks deal, but I made a challenge to try and keep it looking OEM, as if it was an option off the showroom floor, or perhaps a tasteful aftermarket mod. I love to test and tweak and test some more so Im all over that...altho I must say, this car already coasta like a mofo...I can even imagine what Ide do if it would go further with less effort LOL. I might try out a couple different setups as well, front underbody pan, front air dam, both etc.

Thanks for the photo Cd.Going by the photo,the nose may be 'attacking' the airstream as late as the end of the wrap around airdam.
Even though it has an abrupt corner it's embedded within a favorable pressure regime,forcing attached flow.
Once past the rear edge of the front wheels there should be nothing but turbulence all the way down the rocker panel area,rendering the leading spat inoperative.
Also,since the rear of the Camaro is 'open',air cannot pool within the rear wheel wells as would happen more in the 'production' car,and will dive into the void immediately.
The MOONs do offer a solid surface for the air to flow over.On the Trans AM Firebird I think they were good for a 0.024 drag reduction compared to a stamped steel aspirated wheel.
