Ok hopefully one of you can help me out. I have a 68' bug that I recently converted to watercooled with a 2.0 vw engine with a turbo. I have been trying to figure out a way of effectively cooling the motor. I have a single row radiator approx 26'' X 20". I have mounted it in the back of the car directly behind the motor and I am having problems with it overheating. My reasoning behind this placement was that the basic shape of the car more or less is an airfoil (like an airplane wing) so by placing the radiator at the trailing edge of the airfoil I would be putting it in an area of high velocity airflow. Is my reasoning correct?
