Race Tech in a Wind Tunnel: Horsepower and Aerodynamics Story by Dave Salazar of A2 Wind Tunnel: Bonneville is the Mecca of speed and every year land speed race teams journey to the historic site to see if they can go faster than the year before. Top speed records can be so close that sometimes the difference from being a hero to being a zero can be 1 mph or less.
