Anvil Mustang

[hotwheels]

OK, some of you have known about this build and some may have seen some magazine blurbs about it......now, it's finally time to track the build here! Anvil Auto is breaking into the Mustang world in a very huge way! It all started when I heard that Steve Strope of Pure Vision (purevisiondesign.com) (Hammer, Z Nova, 515 Charger, Petrol Charger, etc., etc.) had a '66 Mustang project for sale. I told Steve that the early Mustangs just weren't my cup of tea, but if it were a '69 (my favorite) I may just be interested. Steve did a little homework and realized that some of the components from the '66 project could work on a '69. So, Steve and I decided to look for a good, clean original '69 sports roof that would make a good candidate to go under the knife. After looking everywhere on the west coast, I found one on e-bay right in Steve's back yard in Simi Valley, CA. He went over to the owner's house one night and called me to tell me it looked like it could be the one. Upon Steve's approval, I made a deal with the guy and we went over to the his house to pick it up. It had very little rust and only some driver's side rear damage which isn't an issue (you will see why later).

Nice....

Here's a rendering that Tavis Highlander did early on showing the original concept Steve and I discussed late one evening. I also did a little work with some plastic model kits to try out some ideas before cutting apart our candidate. The final product should be pretty close to this rendering, but more agressive (despite the not so sinister off-white paint).

Steve had the Mustang stripped and had the suspension bits (JME front, Maier Racing rear) on it and a Kaase Boss Nine engine mocked up in it at the Pure Vision display at the Grand National Roadster Show this past January.

NICE!!!!!!!! Cant wait for more!!!

There are a lot of modifications on this car, but some are so subtle that you won't notice them right away. That's sort of Pure Vision's calling card, but I pushed for some things that probably make this a bit more outside of Steve's normal comfort zone. The hardest thing to do is to make changes that don't diverge too far from the factory sheet metal, or seem to anyway, but still enough to be worth the effort. There are Easter eggs all over this car, so I don't want to blatently just list them here as to spoil the fun of finding them. I will, however give some clues. Take a look at the tail panel. It's been modified in more ways than one.



Now, I know the screen is not that subtle, but there are some other things going on there. It will be more apparent when I post some more pics later.

I worked on some of the parts we will be producing in carbon fiber myself including the rear bumper. Originally Steve had the steel bumper de-chromed and I was going to have his guys weld and grind on it to make the mods I wanted, but we both agreed that there had to be a better way, so I went to town on some foam and fiberglass. Mick's guys from Mick's paint did the final touches on it as well as all the other panels that are being molded to make the carbon fiber parts.

[baggins]

just curious are you gonna be making any carbon fiber products for 65/66's?

[ProdigyCustoms]

That wooden bumper is going to be kinda heavy isn't it?

I am sure if Strope is doing it, it will be fantastic. You must be siked!

Here are some pictures of the evolution of our hood design which shows how much work that goes into making a custom part to reproduce in carbon fiber. I never liked the stock 69-70 Mustang hoods with that 'beak' or "ironing board" in the middle. I wanted to modernize it while giving it a functional aspect to boot. I really like the vents in the Aston Martin DBS hood, so we had that as our inspiration.


Here, we performed rinoplasty on the beak and started to build up the hump in foam

More foam, then bondo over the foam and lots of sanding and eyeballing with templates

You can see by the illustration below that the Aston hood's vents are too rounded at that corners for the more angular Mustang, so we tweaked them to be sharper. We also realized from these illustrations that the secondary vents off to the sides and further back on the Aston hood just made the Mustang hood too busy, so we decided to axe them.

Here's a screen shot of the computer model we did in Solidworks

Next we really needed to look at exactly where it made sense to position the vents on the hood. We looked at the underside and we didn't want to have to completely redo the underside bracing, and they needed to be functional, so we reallly only had one area where they made sense. The radiator sits so far back in the car that the more forward recess on the underside is actually where the core support is.

Here it is with one vent in place


Here's the finished hood pattern which we are making molds from

I figured I need to add some weight to the rear end for traction, ha, ha!
I want to run this car against your Project Unfair, Frank. I'm throwin' down the gauntlet!

[OLDFLM]

Lovin' everything about this project my friend!! That hood is sick!

Certainly subscribed...!

Nice, I love 69 Mustangs. I like the rendering

[LeighP]

Wow, thats nice work.....love the hood. And that rear bumper....great lines!

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.

thats gonna be sweet!

wasnt pure vision working on a mustang a little ago called ethos or pathos or somethin?
