I like the screen rear.



One thing though, to optimize flow out of those hood vents, a 1/8" lip should be added to the leading edge, that will help create a small pressure drop inside the vent that will help evacuate air.

You're absolutely right. I've done some research on this subject, and that's why we designed our 1st gen Camaro hood vents that way as well as the vents for 2nd gen Camaros that we will be making. However, aesthetics won out on making these vents have more of a clean look and closer to the Aston vents that the hood was inspired by. I figure if it's good enough for a car like the Aston Martin, it should be good enough for our Mustang hood. I suspect the Aston vents may be more about letting out heat than extracting under hood pressure and that's what we're trying to do. With a composite hood, you want to let the heat out as much as you can. Just ask Larry Callahan! Without doing some wind tunnel testing, it would be hard to tell how effective they are in relieving pressure. Maybe we can do some high speed testing on the track with some small air dams stuck onto the hood in strategic places to see if it seems to help. The tail panel screen is another thing I would like to test on the track with it opened and closed. Since you would normally have the side windows open on the track, the idea is that the air would flow through the car and exit out the back where there is usually a vacuum sucking the car backwards.

The effect of the screen is going to be really hard to test and is going to vary A LOT based on speed. I always chuckle a little when I see guys blasting down the track at 100mph with the windows down. That creates so much drag most would be apalled. You might be better off ducting air from under the car, as far forward as possible, out that rear screen. The effect of the tumbling air behind the car and it's low pressure will help relieve some of the lift from the aerodynamics of the body without the drag enduced by front lips. If you have rear brake cooling ducts that would be a good place for those to vent as well. A brake duct that relies on the wheelwell to vent is going to be significantly less effective than one with a dedicated vent, let alone one in a low pressure area.

The final option for that rear screen would be to use it with air either ducted from under the car or from the quarter windows for a radiator, oil or transmission cooler, even a diff cooler. Check out the Pikes Peak Sonoma GT to see what I mean.

Those are all good ideas and we plan on making use of that rear screen to serve double or even triple duty. Some tracks (I'm talking road race, not drag) require that you run with the windows down, so you don't have a choice. It definitely introduces a lot of drag. We are making the quarter scoops functional to cool the rear brakes. I hadn't thought about having that air then go through the back screen. Mmmmmmmmm, interesting. We didn't plan on making a rear diffuser for the first time out, but it may be in the cards later if we decide it could use it. With the fuel tank there, it may be hard to make the air go from beneath the car through that vent. Worth taking a look at though.

Here's the inspiration for the wheels. Some of you may recall seeing these wheels on some Indy cars from the early 60s. A girl I went to grade school with used to bring in 8X10 glossies of Indy cars her father took who was a pro photog. A lot of the cars wore these wheels. Bitchin'!




Here's the computer model from Evod Industries who will be makng the wheels. They will be available for sale through Anvil Auto early next year.

Matt,
The Mustang looks Fantastic!! I really like the cool hood and bumper work your doing. Sweeeeet!! 69'-70' Mustangs are my Favorite!! The suspension you put on looks Killer and should be a bad *ss pro-touring car!! I can't wait to see this done!! O' by the way, cool Hot Rod TV episode this weekend too!!

I love the style,I love the color...I just love 'em!

Oh, did you catch that episode I was on with Strope and the other sponsors of the Keith Stone (Keystone Lite) 2010 Camaro? That was kinda fun. We're finally shipping the billet side gills and SS badges that we put on that car. It took us a while to get them into production because we of how long it takes to polish and paint them. The gill trim isn't easy to machine as they get pretty thin, but they turned out nice.
