Progress peekaboo!


Actually, I'm done already but I'm gonna drag this out cause I'm a dick... Also I have a lot of other stuff going on.

I've been short on time for both the project and this thread because I got this thing:


But to rewind a few weeks, I purchased a 28"x9"x2.75" bar & plate intercooler from cxracing... It was backordered but showed up eventually. It seemed like the perfect size to fit with minimal valance cutting.

After arrival and a quick pressure test, I ended up cutting about 32"x4" out of the valance itself and then trimming the rear of the horizontals to fit the piping in underneath the headlight brackets.

I will be very specific about the plumbing in case someone wants to do the same:

Turbo side of intercooler is a 90* silcone 2" to 2.5", a 6" straight aluminum and then a 90* silicone into intercooler.

Cold side is another 90* silicone coupler, a large radius aluminum 90*, a 9" straight with BOV flange, a 45 degree silicone and a 12" aluminum with IAT bung, and lastly a 135* 3" to 2.5" reducer.

I used some holes under the hood hinge to mount the intercooler, along with the brackets they provided. While I was in there I installed a SPAL 30101517 2000CFM pusher fan.

Test fit out of the box:

With valance reinstalled:


The only outwardly visible clue there's anything in there:
