This is a post about sealing the gaps around your radiator, and ducting the air through the nose of your car so it has nowhere to go except your heat exchangers (radiator, intercooler, oil cooler, small clothesline for drying your gloves, etc).
I might be able to drive a little bit, but when it comes to mechanical skill, any handiwork really, I am, as one avid newspaper reader so eloquently wrote to my journalist friend, an absolutely dumb idiot.
So here goes. This is my attempt at ducting. It's not pretty, it's maybe even not functional (I am optimistic, but as an idiot, of course I am) but it's an attempt. It's an attempt!
Trackday tomorrow, will report back on effectiveness.
First attempt at the passenger side. Used a cardboard template to get a rough shape, then just kept trimming and test fitting. There are three parts: two side pieces, and a bottom piece. I used coroplast (election signboard stuff), adhesive backed foam, and aluminium cloth tape
Further progress
Driver's side. Ooohh yeah that's some real nice work there, so professional and pretty
Here you can see the bottom piece a bit better. It attaches to the radiator and there is no gap underneath. It effectively makes a sealed chute so that the air through the nose cannot go anywhere but through the intercooler and radiator. I have got any pics but there is also foam sealing the sides of the radiator.
Another view of the front. It looks a bit wonky, but that's just because my intercooler is a bit wonky, and also because it's a bit wonky.
Fin. I also sealed the top section under where the bonnet meets the chassis, but didn't take any pics. Can do later if anyone's interested.
