Brake Duct

[Kaido_RR]

Hey,

Im looking at making some brake ducts for my r33, i came across this on yahoo and through it looked like a good idea and was going to try and make some for an r33

is there a good idea?

Cheers Michael

too right it would be, :-) i take some if you do make them. searched for ages for something like it. would not ba as simple as those i think... well on a R32 anyway and being able to split them rather then removing the drive shaft

now that is a tasty mod...

[R32 GT-R]

it seems like it only cools the very centre of the disc... wouldn't it be better to have a duct cool the outer edge of the disc where the pads make contact or even ducting cool air into the the cooling vanes in the centre of the rotor? I reckon make somthing like a caliper that goes over both sides and the top of the rotor then duct cool air from the front bar into that... just my thoughts.

nah this is perfect, they cool by putting air into the centre of the rotor which runs out through the vanes. If you run cold air directly onto one face of the rotor you can crack it by cooling it unevenly

kn oath!!! il by 4

hrmmm. but thats not a gtr hub but.looks like a subaru one.

lol

i might get some 'super racing cool water but

[dontfeelcold]

would it allow enough airflow to get into the rotor?

[dontfeelcold]

or would you just have to try it?

[Eug]

would it allow enough airflow to get into the rotor?

compared to what? it's definately better than nothing

[T04GTR]

well if it works for formula 1 i rekon it would for our shitboxes

Hey I wonder if you could rig up a water spray like on an intercooler but onto some part of your brakes...

[tacker]

they do spray water onto the brakes of a DTM car but only when they are coming into pitlane as stopping with red hot brakes causes fade when they return to the track or so the article i found said. Also those truck they race pump water onto the brakes all the time.

I have also found some 3" 12 volt fans that are used in nascar to cool brakes down. They are place in the brake ducting and will move 145CFM i think that would help.

used to run water cooling in f1 as well as a way to beat minimum weights....they'd get weighed with 30kg of water on board then dump it on the brakes nice and early, then run around 30kg lighter I still think there is a god chance of cracking them though
