That is what I want to find out as this will be a
trial and error type of experiment. I am religiously following Mitsubishi's take on VGs.

However, the VGs that are installed for generating
streamwise vortices bring drag by itself. The actual
effectiveness of installing VGs is therefore deduced by
subtracting the amount of drag by itself from the
amount of drag reduction that is yielded by shifting the
separation point downstream.

Given that Mitsubishi and Renault have undertaken that strategy, I am certain it has merit, if
properly applied. That is where the challenge resides imo.
