Ducting and paneling thoughts.

Ducting and paneling thoughts.
So on the new car i got it has the FM cross flow radiator but has this ford torus fan on it. YIKEs!!!! So i have ordered 2 small fans to go on the front of the radiator as pusher fans to help clean up the engine bay. I also wanted to panel the whole under side with some 5052 aluminum seeing as we have tons of it at my school and teacher said take what i need. Only thing that sucks is i wont be back at school till the fall. The other thing i wanted to do was duct air into my rad and then have it duct the heated air back under the car to help keep engine bay and intake temps down. I want to do it in a way that i could force cool fresh air into the engine bay and the same for the radiator so this is what i have come up with.
With the way i want to do it it should make the engine bay and radiator inlet area high pressure air flow so there will be little chance for the heated air to come back in the engine bay. The outlet of the radiator should be low pressure but not lower then the air moving under the car.
So any thoughts on what i have come up with so far??

Im not running a turbo setup on this car but i might later on. If i do end up doing turbo im going to water to air cooler it. I have found a heat exchanger that will fit in the ducting before the radiator.

imho.
1. you are assuming the bottom of the engine is a low pressure area. that is likely to be a high pressure area (bottom is not exactly flat, even if you plan to flat bottom it, there still are suspensions, tires and exhaust that's not covered), air exit happens to be where the suspension/tire is, which is probably the most turbulent area. then you won't have pressure delta for effective cooling of radiator.
2. pusher fan is not as effective as puller fan. it loses about 20% efficiency.
3. like other said. that opening is tad a bit too small.
4. cool fresh air to cool off the engine ? that's what radiator do.
5. shroud around the rear of radiator is un-aerodynamic (due to curvature). that will create high pressure, making radiator ineffective.
6. you said the radiator intake is the width of the car. but the radiator exhaust is 1/2 that (you have suspension and tires in the way), that creates high pressure at exit.
in stock config. most air in the engine bay exit through transmission tunnel area anyway, which is to the bottom. so you are designing a complicated system that does the same thing as stock, you are just moving air exit from rear to front. why bother ?
