I think I will get better results by reversing the fans to take heat out of the engine compartment. The fans are defiantly pushing some air and I can feel plenty of heat being drawn thru the radiator.

Hey Todd...I may be wrong about this, but I don't think wiring the fans to blow out is a good idea. The Turbo Porsche is designed to draw air into the engine compartment at speed. Remember, it was originally designed for an air-cooled engine w/intercooler.
Also, there's possibly a low pressure area beneath the car, so blowing air "OUT" might not even be possible...especially at speed. This would only exacerbate the situation and cause the water temps to rise since no air will be traveling over the radiator fins.
I may be off-base about this...someone chime in and give their opinion.
