Steve, a couple years ago I swear there was an aerodynamics sticky on pt.com in advanced tech I believe. I read everything that was linked and found it very straight forward and easy to understand. It even talked about string testing and using two different gauges to monitor pressure differentials across say the radiator to help cooling capacity. Given that the car has no aero mods, you may want to look into adding some. I'm sure a belly pan of sorts would help and not change the way the car looks. It may even help with air flow through the radiator. The author of the links I read used a belly pan to lower his intercooler temps. It was just a matter of monitoring pressure differentials to ensure air was flowing through the engine bay.
