Rebuilding 2005 car and Michigan Research Trip
We rebuilt the 2005 car as practice for our new car and so we knew what changes we needed to make in construction and parts.
Cleaning and Preping our F4i Engine
Working on the chassis
Body Work
Fixing wiring job and setting up the ECU
Good view of the Engine and Drive Train
Taking care of all the little details

Design Drawings+Michigan Research Trip+Chassis Mock-Up
Our initial Chassis Design
Drive Train Drawings
Organization Officers Volunteering at 2009 National Competition, Getting Sponsorship by GM, and Researching Designs

Tilt Test at Michigan
Our PVC Chassis Mock Up next to the 2005 car as a comparison
One of our main goals this year is to save weight, lower the center of gravity, and improve the aerodynamics

Pretty cool... Remind me if I'm ever in Lubbock to bring my F4i and a lot of beer. Maybe I can bribe y'all into some engine work 
Question on one of the photos: How were they tuning car? Is there a PCIII on there or did you guys build your own interface / software to the ECU?

We have a funny tuning set up. Our driver drives around with one laptop while running Zeitronix Data logger. Then they look at that data(Air Fuel Ratio, RPM, and Throttle Position) to tune a Performance Electronics ECU for how long the fuel sprays and the firing angles. Then rinse and repeat until its good enough.
Its a blast especially driving it

That was off the old car so I am not sure. It could be made a lot better, but we have to make custom intakes to fit our restrictor . The restrictor is what affects the fuel air ratio poorly. When we were designing this years intake we noticed that at high revs it really doesn't matter how much throttle you give it, the airflow has already reached its max flow and won't flow anymore.
