Graeme, on the previous page there is a picture of a radiator fan in the doghouse.  What is this for?  If I remember, your cooling mod added a cooling fan to the bottom of the radiator.  I am probably going to bite the bullet and do your cooling mod this fall I already purchased the EMP pump, so since I am going to have most of the cooling system removed anyway, I am going to remove the stock radiator fan and add your cooling ducting on the inside.  I am going to try it without the scoops on the outside and see how she does.

Hi @Tim Morris the reason for the fan in the dog box is to evacuate the engine bay heat. The stock RW system draws all the hot engine air and pushes it through the radiator, hence the RW system is trying to cool the engine with hot air.
I initially tried no scoops but found that you do need to capture the air with some sort of scoop if it is just an opening, the outside air flow will pass it by, as the air once past the vertical join in the lower panel to the front panel causes the air to be turbulent an it just passes by the opening
