Lookee here what I done found!


Racing products design company Hancha did a CFD analysis on 5 different air dam/splitter combinations on a 1st gen Miata.

1) Cd 0.36 = "stock" model: (actual car is 0.38, but CFD model has smooth floor & wheels); 38 hp @ 100 mph

6) Cd 0.29 = model #6 with large air dam & splitter, reduced ride height; 31 hp @ 100 mph.


(Although it does seem to be missing cooling inlets.)
