I believe the car will be stopping by GST tomorrow, and heading up to the Mt. Hamilton event as well.

Update:
I had brought the car to the dyno to receive a return for 100oct gas. The car gets setup and starts the initial pulls. We put in some 100oct gas and start the new pulls. Shortly their after Mike Warfield comes out with this stern look on his face, "Turbo is blown"
However it wasn't as bad as I had initially thought. While "blown" the turbo wasn't dead. It was not able to hold more than 19psi and it would drop to 13psi at redline. According to Mike the VF39 has a casting design flaw which sometimes will cause cracks at the waste-gate and prevent the turbo from holding boost pressure. The car still runs very strong but doesn't pull hard at all up in the RPM range. With this info in mind I am going to complete the setup of the car and then this winter try and remove the turbo to fix it or just outright replace it.

Calculated Risk did all of the cage work. You can contact them at 530-677-2381, and they are located in Cameron Park, just outside of Sacramento. Give them a call and they will take care of you.

Update: Flatbottom Completed
After the last track, event we decided that the car really needed to have the flat bottom completed and we had to do something about the gold wheels that now looked totally out of place on the car.
Calculated Risk has been extremely busy, but the day before the event they were able to complete the full flatbottom on the car. Having never driven a car with a flatbottom I was not sure what to expect, though after the first high speed corner I knew it was entirely worth it. We decided to leave a small gap in the under tray to make sure we were able to vent the engine bay properly. In the future we may decide to find another way to vent the engine bay and seal up the entire under tray. Really the flatbottom in 90% complete. We are going to be adding naca ducts to the rear diff, and come rear brake rotor/hub coolers. We will mostly likely be adding a transmission cooler with its own naca duct as well.
In slow speed corners you would be hard pressed to tell a difference, but in medium to high speed corners you can feel the difference on the car. The faster I went the more of a difference the flatbottom made. You could feel the car becoming more planted as you increased speed, it was fantastic.
Here are some pictures of the belly:
Rota was also kind enough to send of two sets of Torque wheels in a 17"x9" rim with a 30 offset. Unfortunately I don't have any pictures of them at the moment as we are trying to work out fender clearance, but I will get them up shortly. The wheels give the car a much more aggressive stance, and the dark silver color works with the cars scheme.

Oh and does it say "Tommy is gay" anywhere on the fabrication work? if not you might need to ask the CR guys to hook you up with that.

Pro VS Amature
Here is a video of my last event at Thunderhill. What is shown is one lap by two different drivers side by side.
Thunderhill Raceway, Clockwise

The audio is from the video on the left, driven by Brian Lock. It cuts out at the end as I could not get the two different audio streams to overlay properly.
Have fun!
