Tf cooling

[1project2many]

I have wondered about a vent into the cowl area. there are lots of trucks driving around that have disabled the cowl vents inside the truck so you wouldn't have to worry about engine bay fumes inside.

Years ago I spaced the back of a hood up 1" on a TF to help cool a 350. The result was slightly improved cooling at idle but no noticeable improvement when travelling. Parts at the rear of the engine compartment seemed cooler than parts at the front after stopping which was odd. I decided maybe I was imagining the temp difference but once I learned that the base of the windshield tended to be a high pressure area I realized maybe the air from the cowl was moving down through the engine compartment and out, and this may even have prevented some air from moving through the radiator.

Putting some type of vents or louvers into the fenderwell opening into the wheel area could help. I'd have to sit and think to try and picture airflow in that area with a fairly stock bodyline. My hunch is that the movement of the tire will create pressure behind the headlamp openings so any vent would work better low and behind the tire.
