Don't worry the intercooler will be sealed. Anyone know of a place where I can find rubberized weather stripping or something along those lines? I have a way I wanna do it but it's not as good lol

I think you'd be better of just making that last one, the "biggest intake possible" that way you are getting maximum air flow over the bigger TMICs. The heat coming off the turbo can still just trickle up throguh the giant hole there anyways, no need for a chimney.

An extra heat shield would better, as already mentioned.

PM me if you want some help, I run a bigger TMIc.

I have a good size intercooler and I'm using a stock STI splitter that I had to cut the bottom off so it fits on top of the intercooler without rubbing. If you come up with one that fit and would seal and cause more air flow I'd buy it. Let me know when you have one ready to try and I'll buy one.

I'm loving the interest already! I have a prototype in the works right now. It's gonna take a bit so be patient guys. ( I'm going to test it on my car for a bit before I even tell anyone about it). For now, keep the ideas coming! I'm loving the input!

What tmic do you have?The biggest one possible still leaves room on the side for air to rise off the turbo. It will also be sealed as all the other ones are since that is the most efficient way to do this.

The way the seal is going to be makes it a 2 piece splitter. The main part ( the 4 different pics I have shown as just the scoop) plus there will be another piece that adds to the scoop part (for the seal). Now, if you didn't want both the sealed portion and the scooped portion, you would just be able to get the scooped portion until you wanted the seal.

I still want to find a better functional way to do the seal so it works on all intercoolers, so I'm still working on that.

Keep the knowledge flowing!

If you get around to the bugeye models, keep in mind the various scoops out there too... If one had a JDM STi scoop (which many do), the radius of the scoop is different from a replica STi scoop, thus some margin of error could/should be introduced into your design to account for minor differences such as scoop types, manufacturing tolerances, etc..

I was a test fitter for subtle and their splitter to make sure it fit the FXT with either real or replica scoops. (I have a replica)

Here's a couple more photos that I have on my PC but when I get home I can shoot better ones since I have new piping. I purchased the IC two years ago and I think it was a ECS or something with letters like that. I'm sure there's a lot of them out there cause they sold for 300 or so.

I have 2 or 3 friends with bugeyes out there so I def. will make them all fit. The scoops are angled back about 30 degrees to account for air that may try to go over top of the splitter still (I may mess with that angle more when I try fitment on the 04-05 hood scoop. I may also have to drop the height down slightly for other years. As its looking now, I may be able to get away with 02-07 splitters being all the same, 97-01 splitters being the same and then tackling the 08-up.

Well... Snow day today. Im working on a brake duct design in the midst of this intercooler cooling. I ordered an eBay intercooler 20x8 core size 20x14 overall... We will see how that goes

Here is my (basically final) design: It’s a 3 piece design Main splitter, rib insert for front intercooler air, and bottom seal that will have flexible rubber (much like the oem sti one).

Be aware of the size of intercooler. My process west splitter is big, but my AMR TMIC is bigger. It knocks the hood scoop up just a smidge on the left. Normal people don't notice it, but I can tell if something is 1/32 off (graphic design eyes unamused by peoples kerning/tracking type choice.)

just something to consider.

LOOKS AWESOME!!!!!!!!!!!!!

I use a Perrin TMIC right now. I am currently using the stock STi splitter and it comes nowhere near covering it enough.

PM me if you'd like to collaborate on some stuff with this.

I may take you up on that offer. I need to get the ball rolling before anything tho. Were making the splitters for 06-07 wrx's and 97-01 2.5rs's since those are the cars readily available

I have an update... A big one

Made a completly new design.
I'll be making carbon fiber splitters AND PC/ABS plastic splitters.
I have molds made and am about to set up a process for manufacturing these babies!

Expect a final prototype in a few months. It's taken a little longer than I expected to get the right mold materials and design worked up but you guys will be impressed.

This first complete prototype will be for use in a 06-07 wrx/ sti with an sti intercooler and stock hood scoop. I believe it will work for the 02-05 wrx and 04-05 sti with a stock sti intercooler BUT I am not 100% sure yet. I also have a seal in the works for the BIG intercoolers out there but that will come after my first one is made.

Materials are slightly more than expected because of the plastic that must be used for under the hood temps but the cost will still be less expensive than the other aftermarket options out there.

Muahahaha

I "simply" modified my WRX splitter...

Take the WRX splitter off and drill out a few spot welds to remove the deflector pieces from the base of the splitter, on the WRX the deflector blocks out the rear of the opening in the base which is there to accomodate an STI IC. I'm pretty sure the STI splitter uses the same base only different deflectors are spot welded to the top to create a WRX splitter.
Order a seal/bellows for an STI IC for about 30 bucks online. You'll notice the mounting holes for the bellows conveniently line up to the few spot welds that you drilled out.
You just need to fab up a new deflector from some sheet metal, then rivet it to the base. See the photo below, the deflector I fabbed up is on the right, kind of a crappy wide angle shot, sorry.

I did that too... But you aren't using the whole intercooler still. The main hole in the wrx splitter isn't big enough for the other aftermarket intercoolers out there. I also made a completely new splitter out of sheet metal (for fitment mainly) that has a better flow shape. Either way, looks good man!
