Turbulators are a proven engineering method that reduces drag. The key to successfully implementing turbulators is to
engineer it. This requires models and calculations, not simply covering an entire surface with dimples.
A golf ball has dimples around the entire surface because it spins and a new face is constantly presented to the wind. If a golf ball were somehow able to fly straight through the air without turning at all, the dimples would be strategically placed in certain locations, and omitted from others. They probably wouldn't be dimples either.

The dimples on a golf ball are to increase distance by promoting laminar air flow around the ball.
The spin provides the stability (and stops the ball rolling forward after it touches down).
