Default DIY short ram intake insulation box

So I wanted to try this project just because.

I have a cobb short ram intake and a ssac fmic. Cobb's cooler box won't work with the fmic, so here's how I'm going about making my own.



first I removed the intake and loosed all wires and harnesess.

Then I cut the first and most important piece. The one what will seperate the intake from the turbo area. (I didn't take pics up to this point because I didn't know if i'd work)


Then the next piece will block off the area under the IC pipes between the power steering resovoir and the other piece I just made


This is how it will look with the intake


Then I'm going to add the stock funnel part back and cutt it a bit to push air into the area:


Then I'll cove the whole peice from the top

(yes that's the remains of a delicious pizza)


More to come tomorrow

You'll have better results ducting from the fog light area and completely sealing off the air box in the engine bay than you will ducting air through the factory scoop. I did MANY trials for ducting air to boxes back in the day on my 04 wrx. I found the two best to be a 3" duct into the stock airbox and a CAI. The airboxes with short ram intakes just never worked as well. Although IAT was definitely lower when ducting from the fog light area.

At one point I even had a barrel fan that would kick to force cool air into the box from the fender well when the IAT reached above 100*F.

^ that's interesting

I wondering why the scoop doesn't work. Meaning the 3" duct from the airbox is a smaller opening then the 4" scoop end.

My goal was to keep the fogs, which is why I wanted to do the scoop. What if I ran the duct from the front grille rather then fog light cover?

I'll never be able to seal it of completely since there are too many wires and pipes in the way, I'm just going for a best possible effort in keeping the heat away

the way you have it set-up wont do s*** dont want to be blunt,but its not going to do s*** mabey 1-5 degrees cooler which won't make a difference! what turbo you running? if its bigger than vf-34 -18g go with fmic you'll get better results!!! you have to remember the intercooler is going to charge the air going back into the motor.

a) he has a FMIC
b) IAT is figured in when tuning, the car adjusts timing i think depending on the temp..

Today was a long day of trial and error.

The hardest part was getting everything to work smoothly, meaning no hoses getting pinched, no wires getting rubbed. Mounting was a paint too, but I finally got somewhere




Here's the piece that will block the heat coming of the turbo.



Here's the piece installed. The wire harnesses mounted to it.




Only 3 more pieces to go


yes I know it's not too pretty right now. I'm leaving everything clear for now to see how it deals with the heat. If everything is good after a couple drives, I'll paint everything nicely

You inspired me to get off my ass and make a heatshield also


I made my original template out of the side of a cardboard box, then traced it onto some aluminum sheet. I don't have the machine shop required to bend and cut large aluminum sheet, so I cut it with a jig saw into 3 pieces. Once I have cleaned up the edges I will rivet the pieces together to make the 3-sided box

When I get home from work I'll post a couple of photos of my progress.

Well I put everything back the way I had it to grab some initial data

Outside temp was 82

So letting the car idle for 5 min the IAT went form 96 -> 145
Then cruising at 25mph around town temps were at 100
During a wot pull, the temps were at 108
Stopping at light temps went from 100 -> 143 really quick then dropped to 100 once I started driving again.

So temps tend to be a steady 100 unless I'm sitting in traffic.

Time for some results.

The temps outside increased to 85 degrees.

Generally speaking, everything was about 6 degrees hotter with the box on. Max recorded temp was 167, while previously it was 158.

While cursing, temps hovered around 109 and were happy to jump higher and slower to come back down.

So overall, this is a big failure.

But it does show that the stock scoop with a fmic does a great job at cooling the engine bay

You sir, are 100% correct. I did the fog light ram air mod and IATs were 4 degrees above ambient while cruising, compared to 20 without, and 30 with the box
