Probably not much, other than to create a disproportionately large
amount of drag. There must be a huge plume of air coming out of these
gills that destroys the airflow down the sides of the fuselage.
I had a nice photo of an oil streak on Williams Europa, showing flow
reversal just aft of the gills. Conversion of the gills to a rear-facing
exit may prove beneficial (to reducing cooling drag), although care
needed to ensure fuselage composite not overheated. I have the moulds
for such a mod., but never tried it out.
The detailing on Daryl Greenermeyer's Reno Legacy shows the way to go.

What purpose do the Europa "Gills" serve?
