The idea here is to incorporate a small air-scoop in the rear trunk lid which feeds air to a duct connected to the 917 oil cooler.

The air-scoop is only a rough drawing, I hope to review other Porsche race cars and find a suitable air-scoop design that will blend well with the GT rear trunk lid.
Feel free to email me any photos ajserrano@msn.com that you feel will be a good sample Thx!

There is a lot of turbulant air over the rear trunk lid in a 914.
