Keep in mind my goals, the removing air by way of fans mainly is to optimize my rear wing efficiency and its height placement. The fans linked previously are in the 3.5A current range each, acceptable for me.
The NACA inlet duct suggestion raises another question, are they any useful benefit located in a low pressure area?

It's more about the local air velocity.The inlets decelerate the flow,while building static pressure,according to the (Daniel)Bernoulli Theorem.The are a ducted,diverging internal nozzle,fed by the kinetic energy of the oncoming flow just outside the inlet, designed specifically for this application.
Low pressure is associated with high velocity and visa versa,but they can't be in the 'shadow' of the body.Typically,they're in a portion of the body that is attacking the airstream regardless of their location on the body.Sloping nose or underbody,a bulging fender or quarter panel.The 2014 Corvette Sting Ray has a version of them atop the rear fender area exactly for brake cooling.
