What If Build Ideas...for Land Speed Racing

nacca ducts on the front fenders behind the tire plumbed to the engine compartment. Plumbing the engine compartment through the cowl and into the doors would be cool but too complicated imo.

NACCA ducts could work, installed backwards for natural suction. With no inner fenders and the firewall moved back as I have it, ducting to font edge of the door (vertical point between the hinges) and capped to make the vents functional shouldn't be too bad. The firewall is about level with the door hinge pillar. Or cut the whole bottom of the fender off level with the top of the tire like 80-90's IMSA cars. The header exit will likely be there also.
