Feb 07 R&T -The Technology of Drag Racing- in a comment about 
attempting wind tunnel testing on drag race cars "...the output from the 
exhaust pipes is another factor that can't be measured in the wind 
tunnel...the exhaust plume creates a lot of down force..."  "We also have no 
way of knowing what the exhaust plumes do to the aero along the length of 
the body."
