Engine Bay Cooling

[Bob_n_Cincy]

I'm doing fans at the rear to pull air out. My whole rear end is going to be open though with perforated grills though so I will have a bunch of open surface area.

Fireblade,
I attempted this with my rear radiator. It did not work out as there is a high pressure eddy up against the back of the car.
I think this is what is happening to some that are getting exhaust fumes coming back into the car.
