As per the thread where it derailed from Kiwi's great splitters for EG. Let me open up the fog light brake ducts here. - I am running low but do have them for EG coupe and hatch, (no 4 door) with a new batch being popped out in the next few weeks, and I can make them for more types of chassis if I get a bumper and enough requests to make a mold for it. It's not worth it doing 2 or 3 cars that's why I made them for EG and EJ1 since it is so popular and the demand is there.

I can make steel spindle side ducts/boxes custom per order depending on the car, brake calipers and rotor size, so PM me for more details, and we can also discuss on here about any ideas some of you may have for designs or brake cooling setups.

Some may say cooling the rotor is not as important as cooling the caliper, some say the opposite. Many cars like DP and Nascar cool both. I personally cool the caliper since that is where the fluid is and I write the rotors off as expendable since I go through them so fast. The calipers and pistons expand with heat and I have seen binds in the pistons when one didn't cool the caliper(mostly on wilwoods I have seen this issue).

Do you have any pictures of the actual ducts/boxes that you have mounted on or near the brake caliper?

I'd love to see what it looks like

Let me get one uploaded. My car doesn't have the spindle boxes since I mount the tube outlet on my splitter aimed at the caliper, but I will get a pic of a customers for you.

is this a for sale thread or a tech thread?

tech............... in as much as he isnt advertising a price.... ?
Its a fine line. I dont see any foul.

in for pics of the mounting

what about dc's? Has there bee any requests for 94-97 dc front bumpers?
A proper rotor should cool itself, they even have blank rotors that have special viens in the rear to draw air toward the rotor, much like mugen rotor. Brembo makes them. So I'd cool the caliper.

I don't wanna cross "the line" so let's keep it technical as possible with just ideas and suggestions to improve what I made. I have had quite a few DC2 USDM requests actually and have a mold underway that will mount in the lower corners of the grille opening like the OE projector foglights, a prototype will be ready soon hopefully. I do need a DC2 grille foglight housing/plastic trim to perfect the fitment, if anyone has a donation or a set I can borrow let me know.

This is how I mounted my ducts, it holds up during track days just fine, not the best looking installation but I have yet to find a better way. Any ideas out there?

Now that's fabrication/installation quality that hits close to home

considering I just built a few brake ducts for my S2000... I just riveted it to the bumper. Although the duct tape, what appears to be glue, and some random bolts will work... I'd prefer a much more secure method.


and since there's more space behind the bumper cover in the s2000s, I made mine extend to the fender liner, so it was easier to connect and using hose clamps:



Mine go OVER the bumper opening, vs. sit inside it. This allowed a more "stealth" look, even if I had to rivet it with silver rivets on a black bumper. I could always just paint the rivets and call it a day.


mine look like hell, but work. This guy made some that look absolutely amazing:

I'm horrible at working with fiberglass cause I'm impatient.


and looks like someone has a set of EG specific brake ducts already, which admittedly look quite good http://hondamarketplace.com/showthread.php?t=1503747

awesome, I used duct tape on mine too I got from the other guy. I can see how much beefier yours are even though mine have done ok so far.

I would be interested in seeing you fab a quick disconnect for where the duct/hose meets so when removing the bumper you didnt have to re attach hosing.

That would take some engineering into the duct and the hose...
But not insurmountable.. I have a few ideas rolling around in my head.

This could work...I would say plastic would be cheaper and better but this design is easy enough.

This is how I did mine. I used some ducts that I bought from Racer Parts Wholesale. They were $10-15 a piece and gave me two ducts per side. One feeds the brake ducts and the other one is used to feed my turbo with cool air, and the other one is used for some extra ducting to the radiator. So far the setup has worked perfectly, I love that the ducts are not mounted to the bumper so we can quickly remove the bumper without having to disconnect anything.

Ducts mount flush to the bumper


Hose is mounted to the duct with a clamp


Then the hose is routed close to the caliper/rotor. We mounted some PVC pipe inside the hose and used a clamp to mount the duct to the control arm. The duct is tucked up level with the lower control arm and we haven't had any issues yet:

Awesome stuff guys, so many designs and ways to DIY ducting.

HAHA Gotta love it! A saturday afternoon and a cold beer, sometimes the Red Stripe lager overcomes the engineering process and it becomes shortened!

those would work, but starting prices at 42.00 ea??? yikes.
I wonder if they are made in plastic?

known

iTrader: (1)

Yeah or......do they make a plastic v band?

orrrrr

JW puts a regular cheap *** aluminum vband into the resin? Ive seen some of those v band kits for like 15 a piece so an additional ~$30 in materials added into the really nice ducts above.

Sorry if Im ignorant, I have not worked with fiberglass, resin, carbon fiber fabrication so i dont know if metal would work but in theory it sounds good.

The connecting of the ducts to ducting is my one gripe about these very nice ducts.

All that can be done.. but i think if you get those expensive porsche things and make them out of plastic.. and just use an O ring on it that it should stay put.. a press on fit, vs something you have to use a wrench to take off?

known

iTrader: (1)

yeah or the pool store might have some slip fit pieces

JW racing

The duct tape pic was a very old photo that was a mock up actually for the instructions I include in the kit.
Now a days I use regular screw type radiator hose clamps instead of duct tape. I staple the clamps onto the hose that I use so they are always there, just slip the hose over the duct outlet, tighten snug with a number 8mm(not gorilla torque) and voila. It seems to work fast and easy.

my ducts are too flimsy for that hence the duct tape and zip tie method...they were not your design of course

liam821

I really like the way your ducts worked out. Looks great! However it looks like you have more space behind your bumper (ek right?) than my eg. The bumper support/radiator front frame thingy overlaps half of the eg's fog lights so it makes using a duct like yours a bit hard. You can get an idea with the pictures that JW racing posted, noticed the duct outlet is far on one side so it clears the front frame of the civic.

still...with some duct tape and a saw...just about anything is possible!

JW racing

Good observation about the radiator core support. It is tough fitting a package in the limited space of the EG.

why not use these?
