I've had good results on my conversion by concentrating on ducting the air to the bottom part of the radiator below the apron. I'm only using a standard factory radiator but the engine is mildly tuned. Basically I've built an aluminium duct panel behind the valance sloping back up to the radiator - this also helps to keep the underslung oil cooler in the airflow. The picture shows the aluminium lower radiator duct panel and the method of supporting the oil cooler on rubber bobbin type mounts. I extensively used 4 and 6mm dia nutserts during the assembly of the aluminium panel work.
