Cheap & easy brake cooling mod

Philipp

Group,

Since last year, i was looking for a simple solution for keeping the brakes at a lower temperature during lapping sessions (to avoid ice mode...). I think that some sponsors are "working" on it but no finished product has come to the market so far.

Member “ResIpsa” did something very similar (ref: DIY - Brake Cooling Ducts) but having mount points close to the rotors was too complicated for me i.e. didn’t know if it would keep up with sustained heat & chassis movement during events.

So, what i did is based on ModShack "Fag vent DYI", I redirected the vents directly through the wheel well without any other changes.

I thought that speed would bring enough fresh air to the rotors to warn them off between each turns without having to be directly on the rotors. This set-up is actually used by Porsche on GT-2&3’s without any mounting points…
My first event is mid-May, so I will report on rotor temps and overall changes feedback.

Any thoughts / comments are welcomed!

Cheers,


Philipp
p.s. For those wondering the effects of water and road debris on the brakes & rotors; no visible signs or noticeable issues so far.

cool. but is that enough porting to the brakes? would it be better to have the port longer and directed at the calipers?

looks interesting. I'd like to see how it performs when you get some numbers in.

I saw this in person actually a week ago, very clean modification. I'm thinking it will provide what you're looking for

Philipp, I'll have to get back to you on that garage on St. Jacques for exhaust install

I have some doubt on this setup about how much it would sucessfully cold down the rotor. it could for sure but not much..
with all of that turbulence created by the tire/wheel ,, i wonder how much of the fresh air would find his way to the rotor.

would be nice to datalog the temp around the rotor with and without that mod.

C6 corvette uses a very similar setup, except they have a cap on it that draws it down from around a 5" duct to a 1" opening. The Z06 has a flat duct with a 90 degree bend in it that hugs the fenderwell.

Looks good, but it doesnt look too effective.

To be frank with you, i have no hard proof that this mod will prevent brake "ice mode" i have been experiencing during sessions. I am looking for enough fresh air to keep the rotors from reaching the temp level (whatever it is) when they do not work as they should... Usually, on a 30 minutes session, i wouldn’t have any issues before the last 10 to 5 minutes.

I just hope the extra fresh air will keep the rotors temperature below that threshold.

Will try to get some rotor temp readings during initial lapping day in May.

Raoul,
As mentioned before, it is an initial try... I'm aiming to keep the rotors temp just below ice mode zone... maybe this will allow enough fresh air between corners to keep good braking capacity. I will report back.

Nicely cut hole in the fender liner, BTW.

Yeah, that hole didn't look like it was too easy to do.

Check this out. Scroll about half way down. Just a simple plate to bolt up to. I say simple. But could cost more than you would want to pay being there would be some welding involved. Also scroll all the way to the bottum and check out the black end piece attachment that could be had.

I'm really going to see what I can make for myself. Intake ducts for the front are dime a dozen from what I've seen. But the one to the rotor are something else. I feel it could be easily be done though. More or less a flat solid piece (but pretty) with a hole where a ring can be welded to to connect the piping. I'm going to check out are cars this weekend to see if the exsiting dust shield can be transformed somehow. Glad I have several friends who can tig.

looks good philipp, hopefully it works well, have you ever had ice mode at icar? sessions are twenty minutes there and I only get it on my last two laps there

kenchan

really? he probably just used a hole saw like this...
