The 3-mile runway at Kennedy became a laboratory Friday for one of the fastest production cars in the world as Performance Power Racing and Hennessey Performance conducted aerodynamic testing with a Hennessy Venom GT. The Venom raced down the Shuttle Landing Facility's concrete surface several times far exceeding the space shuttle's touch down speed of about 225 mph. The team won't know it's exact speeds until the data is analyzed, but the information gathered during Friday's runs is expected to verify or refine computer design on the rare supercar.
