So I was thinking, all that air is being vented, probably 40%~60% of the time, while the throttle plate is closed on a supercharger system.

This is perfectly good, intercooled air.

Why not split it in 2 and run large hoses to each brake dust shield....

What do you guys think?

 

hate to burst your idea, but....

1. what you gonna do when you go full throttle, dump all the air to your brakes?
complex butterfly mechanics aside, the things to consider that make it non-practical are:

2. the pressure level at part throttle is what, 1-2 psi, max, and at a very low cfm. much more air (cfm) will be provided to the brakes from well designed brake ducting using the 'ram air' effect.

3. intake air is NEVER cooler than ambient temperature,even intercooled/aftercooled because the intercooler will never be cooler than outside temp(baring ice or something), and intake air is typically warmer due to heat soak and the fact that the air was compressed pv=nrt, so its not like your gaining anything in that department

4. also, brakes need to be cooled when in use, and shortly there after...coming out of the turn, you're not going to be part throttle then, back to point 1

but good for thinking

 

Another dream crushed by science....

 

you're going the wrong way, make the heat do work for you, instead of getting rid of it faster

you need to recover the energy lost during braking to use when back on the throttle.

if you figure that one out, for cheap, all the manufactures would be interested, and also some physicist.

think on...

after re-reading your post, do you just want to keep the wheels free from brake dust while driving? you guys with your form > function...haha

 

Eureka! Heat regenerative braking. Enclose your brakes in a tank of water that cools them, converts the water to steam, and use the steam to drive a small turbine at each corner that provides power to run an electric turbo. Cooler brakes, more power=WINNING!

 

More like BIWINNING!

 

Thanks Joe for the schooling! Don't you think even if the air was used for circulation rather than temperature reduction, you would gain > 0º cooling on the rotors? I understand there could be issues with the uneven pressure being pumped in at random intervals.

You would not be braking at full throttle. Yes, it would be nice to keep cooling while on it but the idea was to blast air at the brakes when they are glowing which is right after coming off a high rpm run.

Wouldn't PSI come off an 8k rpm acceleration into max-breaking zone be more in the ~10psi range?

I understand but it would not be hotter than the brake temp.

Yes but compare this to having nothing.

 

Cool Idea, but I think what Joe is getting at is:

If you had properly routed brake ducts from the front of the car it would be more beneficial....

 

Might be fun to fiberglass some "chutes" from the front bumper....

 

Didnt some hybrid mfgr already do that idea? Correct me if im wrong but is this what you are hinting at

http://en.wikipedia.org/wiki/Regenerative_brake

but it does say kinetic instead of heat, so not sure.
