Heat exchangers ducting + forced brake cooling/ducting
 

I needed to redo my radiator/IC/oil cooler ducting and thought I'd post some pics about it.

I have the big ass raditator from TSE
the BEGI #3 intercooler
and a smallish oil cooler (Setrab, wide but only 11 rows or something).

Ducting material is 2mm black plastic (not PVC) and lots of weatherproof ducttape of course.

I extended the 'mouth' of the bumper a little and the ducting from the intercooler side so the two meet and gives a fully sealed chamber.

95% of the air passes the intercooler, all of it the radiator.

This is a sample video with the bumper loosely attached. I run a single 12" fan from chinaland:

I hope your duct tape holds up better than mine did. I had a similar setup and 1 track day in 90 degree heat with 120+mph straights and it all fell apart. I'm in the process of re-designing it using weather stripping and some sort of removable fasteners. It sucks having to re-tape everything whenever you work on the front end of the car.

Ohh, and wheres your oil cooler?

Should hold up. I've done roughly the same before. The tape is just holding the plastic sheet structure together, but we'll see.
Keep us posted. I now have at least the bumper removable without retaping. Making the heat exchangers removable without re-doing it seems impossible.In between the rad en IC:

I'm kinda in the opposite scenario. Mine is riveted to the bumper, but mostly sealed with weather stripping to the radiator. Where my bottom horizontal piece of ducting meets the radiator I've riveted it to thin aluminum angle iron and put a strip of weather stripping on it, then I zip tie it tight against the radiator using the fan mounting tabs on the radiator. Pretty easy to R&R with just cutting and re zip tying, which is much easier than taping.

The hard part is the vertical pieces on the sides... They need to seal against the curving body on top, get around the IC and oil cooler pipes somehow, and seal against the horizontal bottom piece. I think I will split each into two pieces, one riveted to the horizontal bottom piece and the bumper and the other riveted to the body. Have them split around the IC and oil cooler lines so that the bottom of the ducting can come off with the bumper and allow removal of the heat exchangers and their lines, leaving the upper part of the ducting in place... I still need to figure out how I'm going to seal and attach the two halves to one another.

Nice; I always appreciate detailed pics of ducting ideas.

My sheet of paper gets sucked in flat with 8 quarters weighing it down.
2 x 12" thick hi flow spal fans with built in shroud, and tdr i/c.
With my old i/c, the paper was flaccid.

I have just one china 12" fan, no shroud. I think the ducting is fine, but I'll find out tomorrow on the track :)

Your brake duct hose routing is superior to mine. I have discovered that fastening it in place so that it is horizontally parallel with the sway bar is fail, and gets rubbed and crunched in interesting ways. I shall be replicating yours.

I can report that it works very well too! I now run Hawk DTC-60 on all corners and with the ducting and cooling in place I have solid pedal throughout the day. Pit in, the brakes no longer overheat which is a big plus!

The radiator/intercooler ducting works well too. I see temps < 205F for water and < 90F for air.

Spooky can we see a picture of the front of the car with the front end on, I am interested to see how your brake duct inlets sit with the front bumper/spoiler...

GREAT pictures of the ducting, I think i would have installed mine in a way that wouldn't have lasted and this just shows the right way to do it (or one right way perhaps).

My TSE brake ducts are coming from Flyin Miata in the next week or so hopefully.

Actually, I had to redo part of the ducting. Just waterproof duct tape is not enough. So I used high adhesive tape that is good to 266F for attaching the ducting to the head exchangers and filled the space between the top of the splitter and the bottom of the radiator/ducting so it cannot droop. I used styrofoam-like material.

I've used some of your ideas as inspiration for my own radiator ducting project:

built a shroud to duct in the nose
https://www.miataturbo.net/picture.p...379000&thumb=1
sealed it around the intercooler piping at the sides, making it continuous with the OEM plastic tray

bedded in the radiator bottom with spray foam. spray it on and then set the radiator into it.

taped up the radiator top and used a tray from BEIG to finish off the top.

used a small splitter to help encourage air to flow up into the radiator and brake ducting

thx for the inspiration!

Ok, tiny pics sukk. Those look like I would be interested if them, if they were large enough to see.

fair enough. here's a link to the gallery pics: https://www.miataturbo.net/album.php?albumid=463

Very Cool Cold air intake!!

Hey Spooky what kind of headlights are those?
