Good looking project. Look forward to following along.

It has been awhile since we posted an update on the ground Zero Fastback. We have been slammed with customer cars for the past 2 months so I will try to cover most of what's going on in these next coupe posts to catch everyone up. We have finally started back to work on the Mustang and things are coming along. The back end has began to under go so transformation. The new Raxiom LED sequential tail light buckets have been fabricated up and fit, the original gas cap location has been filled and we are currently working on getting the Custom gas cap in it's new location under the rear window. Here is a pic of the buckets roughed in.

Another area we have been working on is the 69 side scoops. I am one of the guys who thinks that if a car has scoops they should be functional, or what's the point. So when it came to the 69 (one of my favorite years) I knew from the get go I wanted these things to do something other than look cool. So we set out to figure out what to do with them. The first thought was to use them to cool the rear brakes...but then that was not really practical or needed. So after much consideration we decided to use them to cool the trans and oil coolers for the supercharger Coyote. To do this we decided to mount one cooler on each side of the inner quarter panel and vent them out to top of the panel. That meant we needed to have 2 of the same size cooler, sealed and modified to mount on inside of the rear Quarters. It also meant we needed to modify the existing side scoops to be functional.
It was not possible to use the original scoops however because you could not weld to the pot metal. So that mean we had to make our own scoops that would fit in the original spot and supply air to the coolers. It also meant we could blend the scoops into the body so they are integrated into the quarter instead of just bolted in. It was important to us to leave the basic shape and position to look like the classic 69,but with a modern flare. To simplify things we used 3" tube that had been slightly elongated which would fit in the space and still supply plenty of air to the stack type coolers. We also had to consider drainage of water and not allow water into the trunk area. Each unit is sealed water tight and the entire set up is angled to allow water to easily drain out, all tubing is smooth bore silicone with stainless Clamps. Here are some pics of the new gas cap location and the side scoops

In my spare time I have been working on getting the Coyote motor ready in my home shop. Little by little it's coming together. The motor is running the stock rotating assembly with only 6k miles on it, and a few additions to support the 650 RWHP that we are shooting for with the Pro-charger P1X that going on it. With the addition of the Stainless 1-7/8 ceramic coated headers the motor should easily meet our goals. We also finished the custom made fuel cell going into the Mustang and installed the Dual 340 Fi-tech fuel pumps to ensure we never run out of fuel.

Sweet Motor! I love the project.

Thanks, We are really enjoying building this car.

So we finally had the chance to mount the new ProCharger P1X on the 550S coyote motor. Everything fit perfectly, although we did have to run the 2011 mustang mounting plate to clear our MMR sheet metal valve covers. We will be working more on the body of the Ground Zero Mustang tomorrow.

O.K So it's been awhile since we posted an update, we have been swapped with work after we started posting on a few forums. But we have been getting a few hours here and there to work on the Mustang. Over the past couple months we have really been concentrating on the tail section trying to get everything the way we want it. We are just about done. The tail light buckets are done, the bumper has been welded to the body and molded in, and the custom exhaust has been installed so I thought I would post a few pics of the before and after. The change is pretty dramtic when you see it like this. I will try to stay on top of posting. Thanks for sticking with us.

When we moved the gas fill from the tail panel to under the rear window we had to also modify the trunk lid, and the weather strip channel to make sure it fit and sealed properly. This is what it looks like from the top, a little more work and this will be done. Today we are working on installing the Martz Aluminum inner panel kit and cage extensions. The we can fit the doors, and fenders in preperation for the hood which will need some modification to due to the coyote configuration we have chosen. More pics to follow as time allows.
