Pics of my Custom SMIC Duct
This is for the Greddy SMIC.
1. I used some heavy weight paper and cut it to shape to find the best fit.
2. Then I took it to a sheet metal shop and had them cut out alluminum pieces to match.
3. After that I had it powder coated with the epoxy based wrinkle black for that stock look and durability.
4. I bought Waterproof heavy-duty Velcro from Home Depot and applied them for the best fit. This included the side of the SMIC.
This set up is better than the sheet metal that was provided from Greddy for the top cover of the factory duct that gave about half of the surface area exposure.

I thought about that.
But decided that a more flexible and easier installation design is better since it's more often then not that one digs around in the engine bay to R&R something.
I like the idea of being able to open just the top and clean out debris that may have gotten in or perhaps for a future external mist device.
I'll have pics of the Duct in the car soon after I get my UIM with matching powder coat on the car to set that "stock" CA smog legal look

looks pretty cool, but all those gaps on the side will decrease the effectiveness of having the duct. you should either attach it so that there is no space there or have it welded.
the air being forced in while driving is going to take the path of least resistance. its easier to go through an opening leading to nowhere than for air to be forced through an intercooler. same concept related to all those threads about radiator ducting and stuff.
as far as debris, don't worry about it. there really isn't any room to get more than road dust up into there.

Well, so far it works and I have no problems.
The velcro is to keep it from coming apart.
The entire duct fits very tight in the engine bay and other structures and components have been the primary support in holding it in place.
This is not ur standard velcro. The standard velcro would not do the job.
This one is much more stiff and VERY sticky.
Even the adhesive is super sticky and hard to pull off once it touches the powder coat.
Also, it's water proof.
There really should be no issues in performance granted that I seal it properly.
I like the install since there was no tools involved and no bloody knuckles.

How much did all the supplies cost? How much time was involved? I might want to do this while I wait for my Pettit duct to be made & shipped....

Hey, it does work........
Well, since i had a buddy that owed me a favor.
So I have no idea on the cost.
but I heard that the sheet metal at Home Depot in the Heat Duct section is a few bucks.
Just be good at cutting and then have it powder coated so that the edges are rounded out a bit. This way u won't curse for cutting urself.

Nice work, but I just wish rx7store or rx7.com would sell an FRP molded duct for this smic, as they both do/can sell this IC. Mabe same shop making the M2 ducts could make them. I spent a lot of time mod'ing a pettit duct.
