Just a tid bit of advice. While first thought would be that the funnelling of all that surface area into a relatively small diameter hole will give you lots of airflow to the brakes/rotors. it probably wont. Most likley you will get a lots of turblulence and reduced airflow. (also increases sc)

Be interesting to see how it goesss. but i would think you are better with a flush panel, whereby helping the cd of the car...and having an opening essentialy the same diam as the duct you are going to run. Its normally the best compromise.

Roy,

All fair points mate and i do tend to agree with you. The reason for them being so big is that i am going to run another duct from each fibreglass panel to the other side of the rotor, the ones you see are for the caliper. I thought that 2 would be better than 1, just waiting on more ducting to arrive.

The inlet you see is 75mm so not small but not huge either. I also do test how much air i get through these with my big f#$& off fan that we use to cool the car down after each run as the pit garages are air conditioned it helps cooling everything down under the car, pic below

The reason is that we do run in temps over 40, yesterday was 46 while i was doing this mod near killed me.

was a problem point and still not where i would like it.

Last time out i ran with the alloy radiator, standard fan, no shroud and a N1 water pump, ambient was 40 degree and i was a little hot with both the after market temp gauge in the engine out let and the Power FC both showing 96 max. Still a bit hotter than i would like but its really too hot to run these cars at that temp, intake temps and knock are the pits mate.

need to update my other thread on this topic too

Yer thanks but i still have top put put the second inlet in the duct and it was easier to do with the front bar back on the car. not to mention quite a bit of filler to put in and sanding to do as you can see

Edited by tacker

nearly finished still have to run two more ducts back to the fronts but made a real difference to the rotor temps and brake pads. No more white edges on the pads any more. and then some better rear ones and thats it

  • 2 weeks later...

Got my act together last night and finished the running of the brake ducts to the font brakes last night.

Also as an after though i put in some CAI which i hope will work, i guess it got to help.

Interesting setup.. I'd be interested in whether channeling the air into such a small defined space is any better than the general flow effect over the wider area.. e.g. just removing the splash guards and allowing the air to pass through.

If you enjoy a more traditional manual, its the choice no question.
