Has any ducted the radiator from underneath the car? This way all of the air from grill can be ducted through fmic and then radiator plus a feed from the bottom. A Vmount would probably work better but if I can make something out of sheet plastic I'd rather do that. The sketch I attached would need some work to actually make and the radiator is closer to the fmic but is just a general idea.

Thoughts?

 

What problem are you trying to address?

 

Nothing in particular. Just an idea I had. Seems good in theory to me but no clue on practice/feasibility
Could be a way to get around a Vmount setup for track use

 

Idk, it seems like to get any decent amount of air flow you'd have to build the scoop fairly large which would make your ground clearance pretty poor. Plus I believe (could be wrong) but the airflow under the bumper is a low pressure zone (i.e. minimal flow gain to the radiator). One option I had considered was using the side ducts that people normally use for brake ducts to get more air on the radiator, but space restrictions can make that tricky/impossible.

If you're having cooling issues, a better dual pass and fan setup would be a better choice. I got better fans and noticed a significant difference in temps. Then if you still have problems you pretty much have to go vmount.
