I had some hub mounted nozzles like SmikeEvo uses but I sold them to someone. I’m using 3” cooling hose so I’m attempting to fabricate my own nozzles that accommodate the larger hose. In the end it all funnels down to the same rather small opening between the caliper and the hub so I’m not sure if it will make any difference.

 

love the idea... let us know if it gets enough air to the brakes.

You might be very surprised if you actually tested it. I'm not saying I have, but the whole front end sees pretty high pressure. It doesn't make as much difference as you would think between the front bumper and the undertray.

 

Like the idea, and especially the funnels, but I look at the front of the 9, and it's screaming for someone to design an integrated duct for the hose to mount to.I used to run dryer hose on my track car, and it worked, looked like crap, but it worked. The Evo's front facia looks like it'd be pretty easy to tap a duct into, and have it look like it belongs there. C'mon you engineer types

 

I like the fact that it may route some the the air under the front lip upward which could make for a little lower pressure under the car and leave more air on the front lip for downforce.

If this was developed a little it may have multiple strong aspects!

 

Your idea looks great curious how you would measure flow. I went with a kit...

 

[QUOTE=82NoMe;5171014]....how you would measure flow. ...QUOTE]

I have no plans to measure air flow nor do I have any idea how this would be accomplished. My plan is to run alternating track secessions with the ducts connected then disconnected/blocked and measure rotor temps see how much lower I can get them. I’ll also closely watch pad wear so see if I can get more life from my pads. But until they scrape the ice of the roads around here this will have to wait until spring.

 

bumping this back up from the dead, I think its a good idea but I'm wondering how it worked out for the OP or if anyone else has tried something like it.

 

WE need to do some comparison test using brake caliper temperature indicator strips.Check out HOERR Racing Products www.hrpworld.com Its a Porsche and GT racing product company. They state that caliper temperatures should not exceed 450 degrees.

 

not to bad

 

I have had the idea to this for a long time. The question was, would it be enough airflow and how can I measure it? I have a way now! Get a cheap MAF from a junkyard. Hook it up to both methods, front bumper duct and this, NACA scoop on tray. The voltage measured will tell you flow.

 

Has this been tested? I'm looking for a ducting solution and i like the looks of this.

 

Shop vac attachments worked for me, but I plan on moving them further back when I lower the car.








To find out if they are working or not, you can use a temperature indicating sticker on the caliper to see if the temperature is changing.

Shop vac budget ducting FTW!! Hope you don't have a marbling track....or dead animals on the roads, or the random tree limb, or or or....

 

Love it! Great idea.
