And yep! Plan is to pull air out through the calipers. I was hoping I'd be able to duct to a low pressure area or build a passive venturi vacuum generator to get the air out. But the more I think about it, the more it seems like I should just make these things active. Stick a fan on the flange and build a small duct to guide the air out of the wheel well nicely. If it's going to be active, then might as well do it properly and add temp sensors and a microcontroller to control fan speed.
This whole idea came to life because the design of the CSL rotors doesn't promote the most airflow from hub to rotor veins. Will likely still install some Bry5on style scoops (will need to adapt his design to my modified dust shield, but that should be simple) to get some extra air to the hub, but this duct I'm designing should help with pad and dust boot temps/life even without those.
