Right guys I'm really suffering from IAT issues and a big part of it is due to the location of my air filter. Behind the rad where its having hot air pumped straight through only to be heated up again by the supercharger. So to combat this, I'm looking at building a custom air box to house the air filter to deflect the heat away from the rad and force cold air from the front of the car in. This is the first time I've done something like this so have a few questions.
Firstly, Material? My two options are have it tigged up in ally. Will be expensive and may look a bit unsightly. Second is i mould it from fibreglass which is seeming more appealing right now. As far as I'm aware, fibreglass should resist the bay heat a bit better than metal and i can form that to any shape i want around everything in the way. Should also be cheaper. Any other benefits to any other materials?
Secondly, air flow. I was planning on using the original scoop off of the slam panel directly into the air box but will that flow enough air? I could always take a scoop from behind the lower grill for a second feed into the bottom of the air box but I'm always wary of this due to picking up water and Matt bushing my engine :p
Will also have the recirc valve feeding back into it as well but thats not an issue as that can feed straight into the bottom where the recirc is mounted anyway.
Cheers all
