I've been making some 3d printed inner ducts to replace the flimsy and unobtainuum VD pieces, with a hope of greatly increasing the airflow through the rad.
Designing them for the right side, but adapting them for the left will be impossible because of the oil cooler and associated plumbing.
This car has been converted to series flow - water enters the top of the left rad, crossed behind the fuel cell, enters the bottom of the right rad, and then returns via the water pump inlet slightly above. This setup greatly improved cooling when I first put it together in '09.
Oil cooler has always been in front of the left radiator. What might I expect if I move it on the other side? might have to make it taller and shorter in length to fit the available outside space.
