So here is my childish drawring. I saw Andrew Brilliants idea of tilting the intercooler back a bit and adding this ramp fin across. I won't be able to tilt it back but adding the fin will cause the air at the top to not clip the top of FMIC and become too turbulent. As well will force all air below through the FMIC. I don;t see a way to efficiently scoop air from below FMIC to rad.



Going to buy some aluminum sheet and this



Once I duct, I should be ok

I will try and leave that sheet in place as I suspect during idle, fan will kick on and simply suck in hot air from engine and not from the front of the rad if I leave it open. Adding a second fan that also comes on would be the only way.
