Rear Brake Ducts

[DanO]

Here's my first attempt to lower rear brake temps by 200 degrees F. I'll test it out at my regular track tomorrow (Monday) and let you know how it goes.

Cool DanO!

You da man - please let us know how it goes and be prepared to give us a full run down of parts, etc.

Cheap, effective, easy, and cheap! Nicky likes it!

Well, the ducts seemed to work well today!

Driver's side rear was 250-300 degrees cooler. Passenger's side was about 150 degrees cooler. I think the passenger's side inlet is too close to the oil pan deflector and therefore does not get as much air...I will inspect further...

The ducts/parts are two 20" sections of 3" 350F neoprene aircraft hose and a bunch of nylon ties. I’m a bit concerned about the durability of the nylon ties so I’ll be inspecting these over the course of the next several track events until I (or someone else) comes up with a better alternative. A 10’ section of hose is about $75.00 shipped from Porterfield, but I bet there are cheaper places to buy the hose, especially since 40” is all that’s needed.

You can get a six foot length for $36 here (click on page 110). Or, if you happen to be going to Acura of Brookfield, you can stop by there as well; it's very close by!

Thanks Dan and Ken - looks very promising!!! I am trying to think of a better way to mount and secure them but nothing comes to mind after looking at your pictures. If someone has any suggestions or I figure something out I will let you know...
