There is a fan already attached to your engine that pumps about 2800 CFM. Be sure the only path into your engine bay is through the intercooler and you're set. That's the advantage Porsche has with intercooling, it's forced air. Check your rubber seal between the sheet metal and body. Also there is a gap between the shock tower and bulkhead that about as thick as your fingertips that runs the width of the bay. Stuff some foam in there to stop the hot air from entering from the ground. This keeps the dirt out of the bay too. As previously mentioned, be sure there is good seal between the top of the intercooler and the wing. Put a light under the car at night and look for paths for hot air to migtrate up from under the car. This is especially important in stop & go traffic. Air is lazy, force it to go through the intercooler by giving it no other choice.
