have a look around carmate narh i meant for us, if we use a hole in the bonnet as the intake path, hydrolock for sure when it rains you can try a slit just above the intercooler and something that feeds air in front of it, then air would pass through the cooler better only thing that kinda scares me is that you remove the heat shielding, in my last car, i removed it cause it was cooking on the manifold, ended up fading the paint directly above the it, even when it poured, that spot on the bonnet would stay dry...
