I looked at Hermann Schlichting's Boundary Later Theory.He addressed this issue,and from the tone of his writing,this is not a project you would attempt without a wind tunnel.
If the air jet is not perfectly sized,sited,and flow calibrated,it will increase drag due to induced vorticity.
If I had to rate the project on a "Buy or Bust" basis,I'd have to rate it a "bust."
