Audi RS6 Boost Gauge Install

I've completed a custom install of a VDO boost gauge in my 2003 Audi RS-6. There are no pre-fabricated pods for the RS-6 so I had to fabricate and customize one of the dash vents to hold the gauge. The install was time consuming, but it came out well and gives me a real time view of boost levels.

I tapped the boost line into the vacuum hose between the fuel pressure regulator and the intake. I had to get a bit creative on how to route the hoses to keep them from kinking. I also replaced all of the other vacuum lines since most looked pretty old and had visible cracks.

Vacuum Hoses and Boost Line

To install the VDO boost gauge in the vent, it took quite a bit of fabrication to use the factory directional vent vanes. They looked pretty rough during the fabrication, but it turned out fine.

2003 Audi RS6 - new purchase

First let me say that the Audi brand and vehicles can be so addictive. First an A4 then a S4 and now the RS6. I wasn't even looking for a new (to me) car until Brandon happen to mention there was an R8 at the import dealership in town. Loretta looked at their Web site and saw they had an 2003 Audi RS6. At first wasn't interested  because I had no reason to get sell the Audi S4. When I drove the RS6, that all changed.....

I wasn't sure I would even like the RS6 because it is automatic and a bigger chassis. After learning from the dealer that the owner had a chip and exhaust installed, I was more interested. The stock HP figures were 450hp and he said this one had over 500hp. At that time all I knew it had was a computer chip and a cat-back exhaust. I drove it and the power was amazing and spool up time for the turbos were really quick. The transmission had normal automatic mode (drive), sport mode (automatic downshifts and quicker shifts), and full manual mode with paddle shifters.

After working with the dealership for a while, we came to an acceptable price for purchase. So I bought the car and traded in our 2004 Dodge Durango because we were no longer going to need it to haul the trailer and Formula Ford. I drove it home and every time I stepped on the gas it made me smile. What I love about turbos is if you drive the car normal you don't realize you have more power. Plus when I was easy on the accelerator I was getting 25mpg on the highway.

Here is the list of modifications at the time of purchase:
  • O.CT engine chip (increased boost and top speed limiter removed)
  • O.CT transmission chip option (quicker shifts)
  • PSS9 Coil over and 9-way adjustable dampers and springs (ride height and dampening adjustable)
  • Hotchkis sport front and rear sway bars
  • 18"x9" wheels with 12mm spacers

    Data Fusion in the Fast Lane - presentation

    On November 13th, 2008 I presented to a class at Penn State's Information Sciences and Technology college. The IST class is about Data Fusion taught by Dr. David Hall, and my presentation explained how data fusion and analysis happens in racing.
    Data acquisition topics Covered:
    • Race car dynamics
    • Sensors / Calibration / Storage
    • Acquisition / Analysis
    View recorded video

    Note: 23 minutes into the presentation I show a YouTube video to the students for additional background information. The audio and video did not come over well to the recorded video. You can view the video using the link below.
