Paul,

At this time we are doing our research on the drag strip but this does
not mean that they wont work. We did not want to invest to much time or
money on long term abuse as the initial test. Our goal was to get them
to work and they did. We will be testing very shortly on a street car on
pump gas. This test will be on turbo application at 20 psi of boost. The
car will be driven daily for at least 30 days. The final test will be
Homestead speed way, 10 laps at full throttle.

We dont know of any one that has gotten as far as us with this aluminum
rotors. We have done what we were told that would not work. At this time
this rotors are not tested for your application but we should be there
very soon.  Our data show that it is possible.

thank you for your time.

Edgar Perez

Thats a great start Edgar. Here is the way Curtiss Wright cooled aluminum rotors
way back when. They used a stack of slitting saws to machine the cooling
fins.
