//Two years in development. Significant time was spent in the wind tunnel and in CAD programs to design the 2005 vehicle. There was great pain taken to balance the features between smooth transitioning curves and reducing frontal area. The introduction of curved underbody features also helped to improve aerodynamics significantly over the 2003/2004 body.

The chassis was redesigned to fit the new underbody fairing as well as improve durability and increase stiffness.

The reduced displacement engine posed many challenges both in development and integration into the vehicle.//

One notable snippet:

//As mentioned by previous posters, Briggs is a sponsor so teams are requires to use a Briggs&Stratton engine. Most teams only use the case (required), replace the shell bearings with balls, de stroke it and sleeve it to a smaller displacement (we used a Honda piston & rod), make a new head with overhead valves (the Briggs is an L head). During are first years we used a modified stock ignition and aftermarket carb but by my senior year we had a pretty sweet ECU with fuel injection (we re-calibrated a GM ECU). Most drive trains at the time were chains to a pillow block with a centrifugal clutch. The total engine/chassis weighed like 80lbs.//
