Cool project
I would like to add from my experiance with aerodynamics without making it to technical is:
1) The more air over the top of the car creates lift. exp. airplane wing
2) As in the pics at the Elephant Racing hood vent ,in front of the car there is a high preasure area that builds greater with speed and the air forced through a cooler becomes less
3)Oil coolers have been installed in the front of racing Porsches forever
4) It is not a fair to compare a 917 to a 911 as far as the frontal area is concerned,as the boundary layers and frontal preasures are not the same
I know I have been kind of direct and with all in involved I show my respect to all answers before this post
I could go on and on about aerodynamics ,but what you are doing is good and dont be suprised if the fans do caome on at a high rate of speed
just my thoughts
