Well.......  Having BTDT, Your looking to high.....  You also need to 
have a open wheel design (MSW Type 55's for me...) To get the air OUT.  
You also want to minimize the run and the amount of cuves required to get 
the air to the brakes..... Then there's the problem of getting more air 
to one side of the rotor then the other and warping the rotor anyway 
because of differential cooling.......  You can get some factory ducts 
from a 200TQ that do help some.... The solution though is to increase the 
cooling AND thermal capacity.... I should have that done soon.....

Later!
