The oil coolers are ahead of the front wheels, as in your Porsche image, as shown in the atttached images. The slots in the fender splash guard have a lower area than the ideal for maximum cooling and people who open them up report improved cooling; the increased drag this creates is unknown and, as expected, the coolers get far more dirt sprayed on them.
The transmission oil cooler I'm looking to fit is a new item. Automatic transmission RX8s have their transmission oil cooler in front of the bottom of the radiator; I want to avoid this if possible as I'm looking at twice the power (400-450 bhp vs 189/212 bhp) with the same radiator area.
My intercooler will be ducted through the bonnet. 1/3 to 1/2 of the rad cooling air will be ducted through the bonnet, with the remainder free to vent either over the turbo & exhaust manifolds then out of a bonnet vent or over the engine then out under the car.
