A full-scale investigative wind tunnel test was performed on a dirt track race car in the Langley Full Scale Tunnel (LFST). Lift and drag forces were measured and flow visualization studies performed for the purpose of quantifying the aerodynamic characteristics in order to assist designers and drivers of this class of vehicle. Results from the downforce measurements showed a rear axle biased aerodynamic balance. Flow visualization studies revealed large areas of separated flow on the forward portion of the side pods as well as over a large portion of the rear deck and spoiler behind the driver.
