We are also adding brake cooling ducts for the front disks and am looking for a source on high-temp 3" diameter hose.

We are also planning on running in-line marine blowers with these hoses to keep the brakes as cool as possible.
Chris - I've used the exact plan you have with the aluminum 3" hose and blowers and it worked great. The only caveat is that the aluminum hose is not very resilient when it comes to any sort of impact. It dents and then comes apart after a while. The high-temp silicone hose is the best but very pricey. You can get it from almost any racing supply house. Check with your local circle-track folks or check with Pegasus Racing online.
To Dan's point about the blowers.
If you check the nose of any Nextel Cup car that is setup to run at Martinsville You will find as many as 8 blowers for the front brakes alone. The blowers do help even when you're moving..
